Compose - Full Track Compositions

Requires: /strudel skill for syntax (notes, sounds, effects, patterns)

Use arrange() to create complete tracks with intro, build, drop, breakdown, outro.

---

IMPORTANT: Examples Are Inspiration Only

The genre examples below show what's possible, not what to copy.

Every track you create should be unique:

• Different chord progressions
• Different rhythms and patterns
• Different instrument choices
• Different arrangement structures
• Your own weird ideas

Study the techniques, then make something new.

---

The Formula

cps = BPM / 60 / 4
cycles = minutes × 60 × cps

Duration	90 BPM	110 BPM	120 BPM	128 BPM	140 BPM	160 BPM	174 BPM
cps	0.375	0.458	0.5	0.533	0.583	0.667	0.725
2 min	45	55	60	64	70	80	87
5 min	112	137	150	160	175	200	217
10 min	225	275	300	320	350	400	435

---

The Pattern

1. Define your elements - bass, drums, chords, leads, atmosphere
2. Calculate total cycles for target duration
3. Build the arrangement - distribute cycles across sections
4. Use stack() to layer elements in each section
5. Present it - show the journey with the output format below

---

Output Format - The Presentation

After creating a track, ALWAYS present it with personality:

1. The Title

Creative, evocative, with emojis that match the vibe:

🎸 BASEMENT SHOW - FEEDBACK AND FURY 🎸
🌙 LATE NIGHT FREQUENCIES 🌙
🚨 SHIBUYA BASEMENT - 4AM - THEY'RE LOOKING FOR US 🚨
🎉 WAREHOUSE PARTY - NO PHONES 🎉

2. The Hook

One line that captures the feeling:

quiet... quiet... LOUD. quiet... LOUD. DESTROY.
3AM. Candles lit. Feeling every emotion.
You descend the stairs. The bass hits your chest. Everyone's eyes are black.
120 CYCLES OF PURE EMOTION

3. The Journey Table

Show the arrangement as a story - what happens when:

Moment	Cycles	What's Happening
INTRO	8	Feedback hums... clean arpeggios
VERSE 1	16	🌑 Quiet - clean guitar, soft drums
PRE-CHORUS	8	Tension... distortion creeping in
CHORUS	16	💥 EXPLODE - power chords, crash cymbal
BREAKDOWN	8	Double-time chaos → silence → feedback
SOLO	16	🔥 Raw screaming lead
FINAL CHORUS	16	💛 MAXIMUM - everything at once
OUTRO	12	Destroy everything... fade to feedback

Use emojis to mark the emotional peaks: 💥 🔥 💛 🌑 😭 🚨 💊 👁️ ✨

4. The Arsenal

List what makes this track special:

The formula:
- F minor - the saddest key
- F5 → Bb5 → Ab5 - power chord progression
- Clean verse → Distorted chorus - classic dynamics
- Contrasting drums - quiet kit vs explode kit
- Feedback always lurking in the background

The sound:
- Distorted kicks punching through walls
- 303 acid in E Phrygian (dark scale)
- 32nd hi-hats like a racing heartbeat
- Sirens sweeping in the distance

The arsenal:
- 6 vocal layers (oohs, aahs, choir, stutter, deep)
- Full UK garage kit with shakers
- 3 levels of supersaw (stab → big → MASSIVE)
- Halo pads floating above it all

5. The Closer

End with a memorable line that matches the vibe:

The bass hits your chest before you see the stage. 💀
3AM. Candles lit. Feeling every emotion. 🌙
We might get arrested but this moment is forever. 💊
You're not leaving this room the same person. 🎨

Learn From These, Don't Copy

What to take from the examples:

• Structure: How to organize elements into variables
• Layering: How stack() builds complexity
• Pacing: How cycle counts create tension and release
• Movement: How filter/gain automation keeps it alive
• Contrast: How breakdowns make drops hit harder

What to change every time:

• Chord progressions - find your own harmony
• Rhythms - your own groove
• Instruments - mix unexpected sounds
• BPM - match the vibe you want
• Arrangement - your own journey
