How it was made

Composed note by note in Moziko by Claude, starting from the prompt “a swashbuckling pirate-adventure theme: galloping 6/8 strings in D minor, heroic horns, brass stabs and timpani, building to a full-orchestra climax”.

  1. New song at 100 BPM in D minor, each beat a dotted quarter so everything gallops in triplet eighths; sections Intro 4 · Theme 8 · Theme 2 · 8 · Storm 8 · Climax 8 · Ending 2
  2. Cello Section Staccato and Double Bass Staccato: a non-stop galloping ostinato on the chord roots (Dm – Bb – F – C – Dm – Gm – A – Dm), the cellos alone in the Intro and crescendoing in
  3. French Horn: an original heroic theme over the gallop; Trombone doubles it an octave down from Theme 2, Violin Section takes it an octave up, and the Climax puts all three together
  4. Viola Section Staccato and Trumpet Staccato: chord stabs on the off dotted-quarters; Violin Section Tremolo shimmering under the first Theme and the Climax
  5. Storm: Trombone and Tuba Staccato growl a call on Gm and Dm, String Ensemble Staccato answers with rising arpeggios, a snare roll and a Timpani Roll on A pull into the Climax
  6. Timpani on the chord roots with pickups, Orchestral Percussion bass drum, galloping snare, crashes, a cymbal swell into the Climax and a gong on the last chord
  7. Ending: two A7 hits and a final D minor chord for the whole orchestra, no fade; mastered with Punchy to −12 LUFS

Listening: The gallop never stops: cellos and basses hammer triplet eighths under every section, so the theme, the brass stabs and the timpani pickups all ride the same 6/8 swing, and the orchestra keeps adding layers until the two A7 hits and the final D minor chord.

How it was made

Made by Claude over MCP.

  1. new_project “Monsoon Circuit”, 174 BPM, F minor; set_sections Intro 16 · Build 8 · Drop 16 · Breakdown 8 · Drop 2 16 · Outro 4
  2. add_track: a 909 “Beat” bus, an Acoustic Kit “Break” layer, Reese Bass + Sub Bass, Dark Pad, FM Bell motif, Pluck stabs, noise riser
  3. set_instrument: Reese with 22-cent detune, 3-voice unison and a slow filter LFO; add_effect saturator + chorus on it, 6 s reverb on the pad
  4. create_clip: two-step beat (kick 1 & the and-of-3, snare 2 & 4, ghost snares, tom fills) under an Amen-style break layer high-passed at 320 Hz
  5. create_clip: atmospheric intro — Fm9 – Dbmaj7 – Bbm9 – Cm7 pad with the break fading in at bar 9 and a dotted-8th-delayed bell motif
  6. create_clip: two-bar reese phrases with octave flicks and fifth/third pickups, doubled by the sub; a variation in Drop 2
  7. create_clip: off-beat pluck stabs answering the snare, snare rolls and risers into each drop
  8. analyze_audio found the drum bus 14 dB over the reese and the pad bed louder than the motif → beat −3 dB, reese +9 dB, pad −3 dB, break/stabs/motif up
  9. analyze_audio: breakdown dominated by the snare roll → softer roll velocities
  10. master punchy, export −14 LUFS

Listening: The first drop render measured −11.1 LUFS with the drum bus at −20 LUFS and the reese at −34.5 LUFS (no band of its own); after rebalancing the drums and reese sat within 2 dB of each other and analyze_audio reported no problems. In the breakdown the snare roll read 9 dB over the motif and was softened.

  1. new_project “Paper Satellites”, 150 BPM, Eb major; set_sections Intro · Verse · Build · Drop 16 · Breakdown · Build 2 · Drop 2 · Outro (64 bars)
  2. add_track: Trap Kit (kick on its own track), Sub Bass, Supersaw chords, Grand Piano, Supersaw lead, FM Bell, Glass Pad, noise riser
  3. set_instrument: 7-voice supersaw with an 85 ms attack so every chord hit re-swells after the kick (sidechain-style pump)
  4. create_clip: Abmaj9 – Bbadd9 – Cm9 – Eb/G | Abmaj9 – Bbadd9 – Cm9 – Fm9 Bbsus4 as syncopated supersaw chops
  5. create_clip: an 8-bar lead hook, doubled two octaves up on the bell and an octave down on the Grand Piano in Drop 2
  6. create_clip: half-time drums (kick 1 + the and-of-3, clap+snare on 3, triplet hat rolls), a doubling snare roll into each drop
  7. duplicate_track: split the chords into Saws L / Saws R panned ±0.75 with different detune after analyze_audio reported a nearly mono drop (corr 1.0)
  8. analyze_audio: chords buried (−35.8 LUFS) and sub-heavy → chords +5 dB per side, sub −2 dB, kick +3 dB, lead +6 dB
  9. analyze_audio: build louder than the drop and a 500 Hz piano build-up in the breakdown → softer roll and saw pulses, piano EQ −3.5 dB at 450 Hz
  10. master punchy, export −14 LUFS

Listening: The first drop render read −16.9 LUFS, nearly mono (correlation 1.0) and sub-heavy, with the chords at −35.8 LUFS; after splitting the chords into a wide L/R pair and rebalancing, it read −14.4 LUFS at correlation 0.92 with no warnings. The build was louder than the drop and the breakdown had a +4.3 dB piano bump at 500 Hz; both were fixed.

  2. add_track ×9: separate Kick, Tops and Perc drum tracks (909 + Afro kits), Sub Bass, Chord Stab, Pluck, E-Piano, Warm Pad, a noise riser
  3. set_instrument: turned the Pluck into a band-passed, gliding mono “vocal chop”; noise riser with a 4 s filter sweep
  4. create_clip: drum grids with hand-placed shuffle (off-16ths late by ~20 ms), conga/clave groove, clap roll into Drop 2
  5. create_clip: Am9 – Dm9 – Fmaj9 – Em11 as rootless stabs (x..x..x....x..x.), last stab pushing the next chord
  6. create_clip: off-beat rolling sub with 16th ghost notes and octave flicks
  7. create_clip: two-cell chop hook sequenced down the progression; E-Piano plays it an octave down in the breakdown
  8. analyze_audio found the kick buried and the sub too heavy → kick +6 dB, F/E bass roots up an octave, stabs −1 dB with EQ −3 dB at 350 Hz
  9. analyze_audio found the hook 15 dB under the stabs → opened its band-pass and lifted it 11 dB in two passes
  10. analyze_audio found a 500 Hz build-up in the breakdown → EQ −3.5 dB at 500 Hz on the E-Piano, −2.5 dB on the pad, hook moved up an octave
  11. master punchy, export −14 LUFS

Listening: First pass: the drop measured −16.9 LUFS with the kick 4 dB under the bass, the chop hook at −46 LUFS and a sub-heavy warning; after rebalancing it measured −14.1 LUFS with no findings. The breakdown flagged a +5 dB low-mid bump at 500 Hz from the E-Piano, cleared with EQ cuts and by moving its hook up an octave.

How it was made

Made by Claude over MCP, starting from the prompt “dark trap with eerie bells, hard 808 glides and rolling hi-hats”.

  1. create_song “dark trap with eerie bells, hard 808 glides and rolling hi-hats”, short form, then set_sections to Intro 8 · Hook 16 · Verse 8 · Hook 2 16 · Outro 4 and cleared the generated clips
  2. write_chords: Fm – Dbmaj7 – Bbm – C (harmonic-minor V) on Dark Pad, two bars each
  3. create_clip: 8-bar bell hook in 3-3-2 rhythm that lands on E natural over the C chord
  4. add_track Grand Piano: the same motif an octave down plays the intro alone, then doubles the bells in Hook 2
  5. set_instrument 808 Bass: glide 0.09 s, decay 2.2 s, drive 0.32, pitch punch 14 st; 808 line follows the kick and slides into each new root
  6. create_clip drums by hand: half-time snare+clap, 8th hats with 1/16-triplet, 1/32 and triplet-8th rolls every second bar, open hats in Hook 2
  7. analyze_audio on Hook 2: bells 7 dB under the drums and 'sub-heavy' → bells +7 dB, piano +5 dB, kick low shelf 2.5→0.5 dB, 30 Hz high-pass on 808 and kick
  8. analyze_audio flagged a +4.3 dB low-mid bump at 500 Hz → EQ cuts on bells (−3.5 dB @ 450 Hz), piano (−3 dB @ 400 Hz) and pad (−2 dB @ 350 Hz)
  9. master punchy, 808 −1.5 dB more, export −14 LUFS

Listening: First pass of Hook 2 had the bells at −26 LUFS against −19 for the drums and a sub-heavy warning; after the level moves the bells sit at −19 LUFS, then a +4.3 dB low-mid bump at 500 Hz went down to +2.9 dB with three EQ cuts, and Hook 2 came back with 'no obvious problems'.

How it was made

Made by Claude over MCP, starting from the prompt “bouncy afrobeats with log drum bass, marimba hook and warm rhodes chords”.

  1. create_song “bouncy afrobeats with log drum bass, marimba hook and warm rhodes chords”, then set_song swing 14 % and set_sections Intro 4 · Verse 8 · Hook 8 · Bridge 8 · Hook 2 8 · Outro 4
  2. set_instrument: turned the Sub Bass into a log drum (square overtone, 9-semitone pitch drop, 0.42 s decay, drive 0.3)
  3. create_clip: Gmaj9 – A6/9 – F#m7 – Bm9 on E-Piano, hand-voiced around a held F#4, sustained in the intro, comping in the verse, syncopated stabs in the hooks
  4. create_clip: 8-bar Concert Marimba hook in off-beat 16th pickups, answered by a Kalimba counter-figure in Hook 2
  5. create_clip drum step grids on the Afro Kit: 3-3-4 rim, accented 16th shaker, conga calls, claps and hats only in the hooks, cowbell for the peak
  6. Bridge for contrast: kick and clap drop out, the log drum goes sparse and a recorded Flute sings a long line over sustained Rhodes
  7. analyze_audio: log drum at −30 LUFS under −22 drums, kalimba/pad inaudible, 500 Hz build-up and a 'nearly mono' verse → log drum +7 dB, Rhodes chorus + pan, marimba EQ dip at 520 Hz, widePad chain on the pad
  8. Second listen: Rhodes was louder than the hook → Rhodes −3.5 dB, marimba +2.5 dB, flute and kalimba up
  9. master punchy, export −14 LUFS

Listening: First pass of Hook 2 measured the log drum at −30 LUFS against −22 for the drums, flagged a +4.8 dB build-up at 500 Hz and called the verse nearly mono; after the level, EQ and chorus moves every section reported 'no obvious problems' with the marimba hook on top (−18.5 LUFS) and the flute leading the bridge.

Yours to keep.

  • One plan, everything in it. The studio in your browser and on your Mac, the AI and the library: €2.95 for 7 days, then €49.90 / month. Cancel anytime.
  • Your songs follow you. Saved to your account in the browser, or on your Mac in the app; export WAV, stems, MIDI or a project file.

  • Works offline. The studio, the composer and a built-in Producer need no internet; the AI that reads your ideas and Claude in the Producer use a connection.

What it doesn’t do (yet)

Moziko doesn’t generate sung vocals, it runs on macOS only, and it doesn’t host VST or Audio Unit plug-ins. It is ad-hoc signed rather than notarized, so the first launch needs one click in System Settings. How to open it

Questions

Questions people ask.

What does it cost?

Making your first song is on us. The Studio plan is €2.95 for 7 days, then €49.90 / month: the studio in your browser, the Mac app, the AI and every library download. Only want library downloads? The Library plan is €0.95 for 7 days, then €49.90 / month. Cancel from your account menu, and billing stops at once. See pricing

Do I need Claude or an API key?

No. Moziko’s AI is built in: it reads your song ideas and runs the Producer. Your own Anthropic API key is optional, and the MCP server lets Claude Desktop or Claude Code drive the app too.

Can I release the music I make?

Yes, what you make is yours. The orchestral, band and world instrument samples are CC0 or public domain and need no credit. The Grand Piano samples are licensed CC BY 3.0, so if a release uses the Grand Piano, crediting “Salamander Grand Piano by Alexander Holm” follows that license; the same goes for the Wurlitzer and Electric Grand with “E-Pianos by Greg Sullivan”, and for the Rock Drum Kit with “MuldjordKit by Lars Muldjord (DrumGizmo)” (CC BY 4.0). Details are on the credits page.

Does it make vocals?

No. Moziko writes and plays instrumental parts. You can record your own vocals onto an audio track, and it can turn a sung or played melody into MIDI.

Why does macOS block it the first time?

The app is ad-hoc signed, not notarized by Apple. Open System Settings → Privacy & Security, scroll to the message about Moziko and click Open Anyway. You only do this once.

Windows or Linux?

Use Moziko in your browser at moziko.co/app: the same studio, AI and instruments, on any computer with a recent Chrome, Edge, Firefox or Safari. The desktop app is for macOS.

Questions people ask

What is Moziko?

Moziko is a music studio for your browser and your Mac. You describe a song in a sentence and it writes a full multitrack arrangement (drums, bass, chords, pads, melody) on real instruments, then you edit it like any DAW: a piano roll, drum sequencer, synths, 26 recorded orchestral and acoustic instruments, effects, a mixer and mastering. An AI Producer makes changes you ask for in plain English.

How much does Moziko cost?

Your first song is on us: make one in your browser, no card needed. To keep going, the Studio plan is €2.95 for 7 days, then €49.90 / month, with the studio in your browser, the Mac app and every library download. The Library plan, for downloads only, is €0.95 for 7 days, then €49.90 / month. Cancel anytime from your account; billing stops at once.

Which computers does Moziko run on?

Any computer with a recent Chrome, Edge, Firefox or Safari, in the browser. The desktop app is for Macs with macOS 13 Ventura or later, both Apple silicon (M1 and later) and Intel.

Can I use the music I make in Moziko commercially?

Yes. Songs you make are yours, and the 10,000 songs in Moziko’s music library are royalty-free with no credit needed, for videos, games, podcasts, apps and commercial releases. The one sound with a credit request is the Grand Piano (CC BY 3.0); see the credits page.

How is Moziko different from Suno or Udio?

Suno and Udio generate a finished audio file. Moziko writes the song as editable notes played by its own instruments, so you can change any part, sound or note, and every AI change is one undo step. Moziko does not sing or generate vocals.

Can Claude use Moziko?

Yes. Moziko has a built-in MCP server with 47 tools, so Claude Desktop, Claude Code and other MCP apps can compose, arrange, mix, master and export songs, and listen to their own renders to check the result.

Does my music leave my Mac?

Your projects and audio stay on your Mac. When you create a song from an idea, the text of the idea is sent to Moziko’s AI to plan it, and Producer requests send your message with a compact summary of the song. You can turn the AI off in Settings to keep everything local.

  4. create_clip: four-on-the-floor with 16th hats, syncopated rims, toms and a 4-bar snare roll into the return
  5. create_clip: rolling 16th bassline off the kick (e-and-a) over Dm – Bbmaj7 – Gm9 – A7sus4, two bars per chord
  6. create_clip: arpeggio that evolves from a 3-note 8th cycle to 5- and 7-note 16th cycles, so the accents drift against the bar
  7. create_clip: lead theme introduced in the breakdown over the string swell, then doubled in length on the return
  8. analyze_audio: kick buried and bass sub-heavy (its −12 st oscillator reached ~24 Hz) → kick +3 dB, octave oscillator removed, bass +4 dB, lead +6 dB
  9. analyze_audio: kick now sub-heavy → tuned it up 2 st with a −2.5 dB low shelf at 55 Hz
  10. analyze_audio: 500 Hz build-up in the breakdown from the strings → EQ −6 dB at 500 Hz, +2 dB air
  11. master punchy, export −14 LUFS

Listening: The first render of the return measured −16.6 LUFS, sub-heavy, with the kick 2 dB under the string swell and the lead at −37 LUFS; after rebalancing it measured −12.9 LUFS with no findings. A 500 Hz low-mid bump in the breakdown (+4.1 dB) was cut on the strings; only the intended “thin low end” of the kick-less breakdown remains.

  8. analyze_audio found the drum bus 14 dB over the reese and the pad bed louder than the motif → beat −3 dB, reese +9 dB, pad −3 dB, break/stabs/motif up
  9. analyze_audio: breakdown dominated by the snare roll → softer roll velocities
  10. master punchy, export −14 LUFS

Listening: The first drop render measured −11.1 LUFS with the drum bus at −20 LUFS and the reese at −34.5 LUFS (no band of its own); after rebalancing the drums and reese sat within 2 dB of each other and analyze_audio reported no problems. In the breakdown the snare roll read 9 dB over the motif and was softened.

  2. add_track: Trap Kit (kick on its own track), Sub Bass, Supersaw chords, Grand Piano, Supersaw lead, FM Bell, Glass Pad, noise riser
  3. set_instrument: 7-voice supersaw with an 85 ms attack so every chord hit re-swells after the kick (sidechain-style pump)
  4. create_clip: Abmaj9 – Bbadd9 – Cm9 – Eb/G | Abmaj9 – Bbadd9 – Cm9 – Fm9 Bbsus4 as syncopated supersaw chops
  5. create_clip: an 8-bar lead hook, doubled two octaves up on the bell and an octave down on the Grand Piano in Drop 2
  6. create_clip: half-time drums (kick 1 + the and-of-3, clap+snare on 3, triplet hat rolls), a doubling snare roll into each drop
  7. duplicate_track: split the chords into Saws L / Saws R panned ±0.75 with different detune after analyze_audio reported a nearly mono drop (corr 1.0)
  8. analyze_audio: chords buried (−35.8 LUFS) and sub-heavy → chords +5 dB per side, sub −2 dB, kick +3 dB, lead +6 dB
  9. analyze_audio: build louder than the drop and a 500 Hz piano build-up in the breakdown → softer roll and saw pulses, piano EQ −3.5 dB at 450 Hz
  10. master punchy, export −14 LUFS

Listening: The first drop render read −16.9 LUFS, nearly mono (correlation 1.0) and sub-heavy, with the chords at −35.8 LUFS; after splitting the chords into a wide L/R pair and rebalancing, it read −14.4 LUFS at correlation 0.92 with no warnings. The build was louder than the drop and the breakdown had a +4.3 dB piano bump at 500 Hz; both were fixed.

  6. create_clip: congas, clave and shaker groove; clap rolls and risers in each pre-chorus
  7. analyze_audio: the recorded marimba read −19.5 LUFS (12 dB over the kick) with a +6.5 dB build-up at 500 Hz → marimba −10 dB and EQ −3 dB at 500 Hz; kick, bass, tops and perc raised
  8. analyze_audio: piano mud at 500 Hz and flute harshness at 2 kHz in the verse → EQ −4 dB at 450 Hz on the piano, −4.5 dB at 1.8 kHz on the flute
  9. analyze_audio: drop no louder than the verse → hook, chords and pad lifted 2–3.5 dB, piano eased
  10. analyze_audio: break still bright at 1–2 kHz → flute down an octave, perc −3.5 dB at 2 kHz; delete_clips moved a misplaced hook and riser
  11. master punchy, export −14 LUFS

Listening: The first drop render read −12 LUFS with the recorded marimba 12 dB over the kick and a +6.5 dB low-mid bump at 500 Hz; after rebalancing, the drop measured −14.9 LUFS (about 2 dB over the verse) with no findings. Verse and break warnings (piano mud, flute and conga brightness around 1–2 kHz) were cleared with EQ and by moving the break flute down an octave.

Made by Claude over MCP, starting from the prompt “dark trap with eerie bells, hard 808 glides and rolling hi-hats”.

  1. create_song “dark trap with eerie bells, hard 808 glides and rolling hi-hats”, short form, then set_sections to Intro 8 · Hook 16 · Verse 8 · Hook 2 16 · Outro 4 and cleared the generated clips
  2. write_chords: Fm – Dbmaj7 – Bbm – C (harmonic-minor V) on Dark Pad, two bars each
  3. create_clip: 8-bar bell hook in 3-3-2 rhythm that lands on E natural over the C chord
  4. add_track Grand Piano: the same motif an octave down plays the intro alone, then doubles the bells in Hook 2
  5. set_instrument 808 Bass: glide 0.09 s, decay 2.2 s, drive 0.32, pitch punch 14 st; 808 line follows the kick and slides into each new root
  6. create_clip drums by hand: half-time snare+clap, 8th hats with 1/16-triplet, 1/32 and triplet-8th rolls every second bar, open hats in Hook 2
  7. analyze_audio on Hook 2: bells 7 dB under the drums and 'sub-heavy' → bells +7 dB, piano +5 dB, kick low shelf 2.5→0.5 dB, 30 Hz high-pass on 808 and kick
  8. analyze_audio flagged a +4.3 dB low-mid bump at 500 Hz → EQ cuts on bells (−3.5 dB @ 450 Hz), piano (−3 dB @ 400 Hz) and pad (−2 dB @ 350 Hz)
  9. master punchy, 808 −1.5 dB more, export −14 LUFS

Listening: First pass of Hook 2 had the bells at −26 LUFS against −19 for the drums and a sub-heavy warning; after the level moves the bells sit at −19 LUFS, then a +4.3 dB low-mid bump at 500 Hz went down to +2.9 dB with three EQ cuts, and Hook 2 came back with 'no obvious problems'.

Made by Claude over MCP, starting from the prompt “neo-soul with rhodes chords, upright bass and a lazy swung groove”.

  1. create_song “neo-soul with rhodes chords, upright bass and a lazy swung groove”, then set_song swing 58 % and set_sections Intro 4 · A 8 · B 8 · A' 8 · Outro 4
  2. create_clip: hand-voiced rootless E-Piano chords — Fm9 · Bb13 · Ebmaj9 · Cm9 · Gm11–C7#9 · Fm9–Bb7b9 — rolled in the intro, pushed comping in the A sections
  3. set_instrument Double Bass Pizzicato: walking/syncopated line with chromatic approach notes into every chord
  4. set_instrument Soft Lead (glide 0.06 s, light vibrato): a lyrical 8-bar melody, embellished the second time
  5. B section for contrast: half-time drums with ride and a tom fill, Grand Piano sings the high line, String Ensemble pad enters (write_chords)
  6. create_clip step grids on the Acoustic Kit: ghost snares, 16th hat pushes, open hat and ride in A'
  7. analyze_audio on A': lead under the bass, strings at −36 LUFS, +3.9 dB build-up at 500 Hz → lead +5 dB, Rhodes EQ (−2.5 dB @ 420 Hz) + chorus, strings EQ'd and up 6 dB
  8. The 500 Hz bump came from the lead's own register → lead EQ dip, master switched from warm to balanced, and transform_clip transposed the A' melody up an octave for the peak, which cleared A'
  9. export −14 LUFS

Listening: First pass of A' put the lead (−26.8 LUFS) under the upright bass and flagged a +3.9 dB build-up at 500 Hz; after level and EQ moves, plus taking the A' melody up an octave, A' reads 'no obvious problems' with the lead on top at −19.2 LUFS. The first A section keeps a milder 500 Hz lift from the low melody, on purpose.

  3. create_clip: Gmaj9 – A6/9 – F#m7 – Bm9 on E-Piano, hand-voiced around a held F#4, sustained in the intro, comping in the verse, syncopated stabs in the hooks
  4. create_clip: 8-bar Concert Marimba hook in off-beat 16th pickups, answered by a Kalimba counter-figure in Hook 2
  5. create_clip drum step grids on the Afro Kit: 3-3-4 rim, accented 16th shaker, conga calls, claps and hats only in the hooks, cowbell for the peak
  6. Bridge for contrast: kick and clap drop out, the log drum goes sparse and a recorded Flute sings a long line over sustained Rhodes
  7. analyze_audio: log drum at −30 LUFS under −22 drums, kalimba/pad inaudible, 500 Hz build-up and a 'nearly mono' verse → log drum +7 dB, Rhodes chorus + pan, marimba EQ dip at 520 Hz, widePad chain on the pad
  8. Second listen: Rhodes was louder than the hook → Rhodes −3.5 dB, marimba +2.5 dB, flute and kalimba up
  9. master punchy, export −14 LUFS

Listening: First pass of Hook 2 measured the log drum at −30 LUFS against −22 for the drums, flagged a +4.8 dB build-up at 500 Hz and called the verse nearly mono; after the level, EQ and chorus moves every section reported 'no obvious problems' with the marimba hook on top (−18.5 LUFS) and the flute leading the bridge.

  5. create_clip: Sub Bass locked to the kick with ‘and-a’ pickups; held roots in the Pre build while the snare rolls from quarters to 16ths
  6. add_track Dream Arp (verse and Hook 2) and Bell doubling the hook an octave up in Hook 2; Warm Pad with the widePad chain in the Pre, Break and Hook 2
  7. analyze_audio on Hook 2: sub-heavy 808 kick at −18.9 LUFS burying the hook (−29.5) and a nearly mono image → kick decay 0.6×, drum EQ −1.5 dB low shelf, pluck +7 dB with longer decay, keys panned left with chorus, arp right
  8. Second listen: keys louder than the hook and a 250 Hz build-up in the verse → keys −4.5 dB plus EQ (high-pass 180 Hz, −2.5 dB @ 280 Hz), lead EQ dip at 500 Hz
  9. master punchy, export −14 LUFS

Listening: First pass of Hook 2 was sub-heavy, with the 808 kick at −18.9 LUFS and the pluck hook buried at −29.5 LUFS in a nearly mono mix; after the kick, level, pan and EQ moves the hook leads at −20.3 LUFS over the drums and bass (−21.9) and Hook 2 reports 'no obvious problems'.

How it was made

Made by Claude over MCP, starting from the prompt “slow evolving ambient with glass pads, harp and a distant violin”.

  1. create_song “slow evolving ambient with glass pads, harp and a distant violin”, removed the drums, set_sections Opening 8 · Drift 8 · Bloom 8 · Fade 4
  2. create_clip: hand-voiced pads — Dmaj9 · E/D (the lydian II-over-I shimmer) · Bm11 · Gmaj9, two bars each, then one chord per bar in the Bloom
  3. set_instrument: Warm Pad with slow 0.07 Hz filter LFO and 2.2 s attack, Glass Pad with amplitude LFO and 5 s release, widePad chain and chorus
  4. Harp ripples (8ths in the Drift, 16ths in the Bloom) through a dotted-quarter ping-pong delay; Glockenspiel lights; return reverb stretched to 7.5 s
  5. Solo Violin: a distant three-note call in the Drift, then the full 8-bar song in the Bloom, ending on a held F#5 over a final Dmaj9 with a G# glint
  6. analyze_audio: harp at −18.6 LUFS dominating, the Drift's violin at −40.7 LUFS, 500 Hz build-up of +8.5 dB → harp −5 dB with EQ (high-pass 180 Hz, −3 dB @ 450 Hz), violin up, Warm/Glass Pad EQ dips; removed doubled chorus/reverb inserts left from create_song's chains
  7. Drift read dark (presence −33 dB, air −42 dB) → glockenspiel lights in the Drift, +3 dB high shelf on the Glass Pad, a soft sub drone underneath
  8. master balanced measured on the Bloom (section renamed 'Drop' for the measurement, then back), limiter +1.4 dB so the export reaches −14 LUFS without hitting the peak cap

Listening: First pass: harp at −18.6 LUFS over everything, the Drift's violin call at −40.7 LUFS, and a +8.5 dB low-mid bump at 500 Hz in the Drift. After the fixes the violin leads the Bloom, the Drift's bump fell to +4.7 dB with presence up from −33 to −22 dB, and the remaining mild 500 Hz lift was left alone because it is the body of the harp and pads.

How it was made

Composed note by note in Moziko by Claude, starting from the prompt “a swashbuckling pirate-adventure theme: galloping 6/8 strings in D minor, heroic horns, brass stabs and timpani, building to a full-orchestra climax”.

  1. New song at 100 BPM in D minor, each beat a dotted quarter so everything gallops in triplet eighths; sections Intro 4 · Theme 8 · Theme 2 · 8 · Storm 8 · Climax 8 · Ending 2
  2. Cello Section Staccato and Double Bass Staccato: a non-stop galloping ostinato on the chord roots (Dm – Bb – F – C – Dm – Gm – A – Dm), the cellos alone in the Intro and crescendoing in
  3. French Horn: an original heroic theme over the gallop; Trombone doubles it an octave down from Theme 2, Violin Section takes it an octave up, and the Climax puts all three together
  4. Viola Section Staccato and Trumpet Staccato: chord stabs on the off dotted-quarters; Violin Section Tremolo shimmering under the first Theme and the Climax
  5. Storm: Trombone and Tuba Staccato growl a call on Gm and Dm, String Ensemble Staccato answers with rising arpeggios, a snare roll and a Timpani Roll on A pull into the Climax
  6. Timpani on the chord roots with pickups, Orchestral Percussion bass drum, galloping snare, crashes, a cymbal swell into the Climax and a gong on the last chord
  7. Ending: two A7 hits and a final D minor chord for the whole orchestra, no fade; mastered with Punchy to −12 LUFS

Listening: The gallop never stops: cellos and basses hammer triplet eighths under every section, so the theme, the brass stabs and the timpani pickups all ride the same 6/8 swing, and the orchestra keeps adding layers until the two A7 hits and the final D minor chord.

How it was made

Made by Claude over MCP, starting from the prompt “epic hybrid trailer with orchestral percussion, staccato strings, brass stabs and a growling reese bass”.

  1. create_song “epic hybrid trailer with orchestral percussion, staccato strings, brass stabs and a growling reese bass” (genre cinematic), kept the percussion, strings, violins, pad and bass, deleted the harp, set_sections Intro 4 · Build 8 · Rise 8 · Peak 8 · Hit 4
  2. set_instrument String Ensemble {articulation: Staccato}: a 16th pedal-D ostinato over Dm – Bb – Gm – A, crescendo across Build and Rise
  3. add_track Brass Section ×2: Staccato stabs in 3-3-2 rhythm from the Rise, and a sustained 8-bar theme in the Peak doubled an octave up by the Violin Section
  4. Orchestral Percussion by hand: bass drum and timpani 1–5 patterns, a snare 16th→32nd roll, and cymbal swells placed 5¼ beats early so they crest on the downbeat (timed with a test render)
  5. Low end: Cello Section and Double Bass roots, Reese Bass with drive, and a Sub Bass turned into a pitch-drop 'boom' for the section hits
  6. Rise tension: Violin Section Tremolo climbing D5→E6 and a Timpani Roll crescendo; one beat of silence before the final tutti D, gong and crash
  7. analyze_audio: brass stabs peaking +2.7 dBFS pre-master and burying the theme, reese/sub at −33…−36 LUFS → stabs −8 dB with a fast compressor, theme +6 dB, reese +9 dB with an EQ, sub +6 dB
  8. Second listen: 2 kHz harshness → theme −2.5 dB @ 2.2 kHz, violins −2 dB shelf; final chord thinned with edit_notes; theme EQ'd −2.5 dB @ 420 Hz
  9. master measured the intro because no section was called chorus/drop/hook → renamed Peak to 'Drop' with edit_section, mastered punchy, renamed it back; export −14 LUFS

Listening: First pass of the Peak had the staccato brass at −18.6 LUFS (peaking +2.7 dBFS pre-master) over a −25.8 LUFS theme, with the reese and sub nearly inaudible; after the fixes the theme leads the Peak at −20.5 LUFS, the Peak reads 'no obvious problems', and re-mastering against the Peak instead of the intro moved the limiter from +1.2 dB to −3.3 dB, so the track builds from −13 LUFS (Rise) to −11.7 (Peak) to a final hit that peaks at −10.1 LUFS short-term (pre-normalization).

How these were made

No hidden steps.

Every track started in Moziko and never left it. Most began with create_song and a one-line prompt, then Claude rewrote the chords, wrote its own hooks and drum patterns, changed sounds and effects, and arranged the sections. The orchestral and piano pieces were composed note by note.

Before each export Claude rendered the song with analyze_audio to check loudness, balance and spectrum, and with analyze_harmony to check the chords, then fixed what it found. Mastering used Moziko’s own chain. The MP3s here are 160 kbps and matched to −14 LUFS so you can compare them fairly.

The sounds are Moziko’s synths, drum machines and recorded instruments. There are no sample packs, loops or stems from anywhere else.
