- Changed all 7 helper functions (folk, carol, pub, spirit, world, rhyme, rag)

units represent eighth notes at the given BPM

- Fixed specific rhythm patterns for well-known songs:
- Happy Birthday: correct 3/4 pickup rhythm (1,1,2,2,2,4 pattern)

The NURSERY_PIECES IIFE referenced 'baa' (Baa Baa Black Sheep) in its return
array but the variable was never defined — it was lost during the Prime genre
merge. This ReferenceError crashed the script on load, preventing all genre
tabs and rhythm lists from rendering.

Gamepad auto-detection:
- First gamepad connect counts buttons and auto-enables matching lanes
- 5 buttons = standard Rock Band kit (lanes 0-4, default)
- 6+ buttons = auto-enables extra lanes (crash, ride, tom3)
- Shows button count in gamepad status: "🎮 Controller (9 buttons)"
- User can still manually toggle lanes on/off (overrides auto)
- Only runs once per session (doesn't re-detect on reconnect)
Keyboard remapping:
- New "⌨ Remap Keys" button in the sticky start bar
- Full-screen overlay walks through each lane: "Press key for RED"
- 300ms cooldown between steps to prevent double-triggers
- Escape cancels the remap flow
- Saved to localStorage ("drgameKeyMap") and restored on page load
- Reset All Data also resets keyboard mappings to defaults
https://claude.ai/code/session_016nhMjrAqwWXKKgBm6EQuX1
Lane system expanded to 8:
- Original 5: Red (F), Yellow (G), Blue (H), Green (J), Kick (Space)
- New 3: Crash (D), Ride (K), Tom 3 (L) — off by default
- New drum sounds: crash (long noise burst), ride (metallic ping),
tom3 (deep 90Hz tom)
Kick lane visual overhaul:
- Kick notes now fall from the TOP of the screen at full speed,
traveling through the pad lanes down to the kick hit zone
- Kick zone still centered at bottom with its own hit line
- Previously kick notes only appeared in the short bottom zone
Other changes:
- Remap system dynamically reads LANES array (supports any count)
- Gamepad default mapping extended for buttons 5-7
- laneFlash expanded to 8 lanes
- All existing songs/rhythms (lanes 0-4) work unchanged
- New lanes 5-7 are off by default, toggle on in Active Pads

Moved 6 Prime songs (Twinkle Twinkle, Mary Had a Little Lamb, Happy
Birthday, Chopsticks, Lavender's Blue, Shortnin' Bread) into the
Nursery Rhymes genre using the rhyme() helper. Dropped Baa Baa Black
Sheep since it's the same melody as Twinkle Twinkle. Updated README
to reflect 18 genres, 124 synth pieces.
https://claude.ai/code/session_01FNZw4curZbJp38HFUaPXwR
New genres:
- Nursery Rhymes (10 songs): Baa Baa Black Sheep, London Bridge,
Old MacDonald, Row Row Row Your Boat, Three Blind Mice,
Itsy Bitsy Spider, Pop Goes the Weasel, Hot Cross Buns,
Jack and Jill, Humpty Dumpty — all at slow tempos (65-85 BPM)
- Ragtime (8 songs): The Entertainer, Maple Leaf Rag,
The Easy Winners, Elite Syncopations, Solace, Peacherine Rag,
The Cascades, Pineapple Rag — all Scott Joplin (public domain)
Simple/Full mode:
- Toggle in Active Pads card switches between Full and Simple density
- Simple mode enforces 350ms minimum gap between notes, removing
rapid passages while keeping the melody recognizable
- Works on both synth genres (classical/folk/etc) and rhythm patterns
- Lightweight: just a filter on the note array, no piece data changes
https://claude.ai/code/session_016nhMjrAqwWXKKgBm6EQuX1
Prime genre changes:
- Reduced tempos: Twinkle 100→75, Mary 110→80, Birthday 100→75,

- Reduced passes from 3-4 to 3 across the board

Toccata & Fugue in D Minor: Fix opening mordent A-G-A (whole step)

Replaced 5-line tp() call with full conductor-style arrangement:
- Continuous Bb major harmonic bed across 8 sections
- tutti() helper for full orchestral hits
- gallop() helper for the iconic 9/8 compound rhythm
- 8 sections: intro tremolo → first horn call (p) → second statement (f)
→ Eb major development → fff recapitulation → climax → power chords → coda
- Famous ascending Bb-D-F arpeggio as hittable melody
- Running string arpeggios as background texture
- Duration expanded from ~35s to ~88s
https://claude.ai/code/session_01TFVkxq4PYhkSFGYHEi4uqY
Following the uploaded lead sheet, rewrote O Fortuna with:
- Continuous harmonic bed (sustained string chords throughout)
- tutti() and choir4() helpers for full orchestral/SATB choir hits
- Running string arpeggios as background texture (not hittable)
- 9 sections following the score structure with tempo changes
(ff opening → pp verses → mp building → f marcato → ff climax → fff finale)
- Duration expanded from ~35s to ~95s
- Only main choral melody accents are hittable (conductor experience)
https://claude.ai/code/session_01TFVkxq4PYhkSFGYHEi4uqY
New "Prime" genre appears first in the genre tabs, designed for

https://claude.ai/code/session_01ELEFwNKTnZvM39VK9wsYd4
Songs corrected:
- Amazing Grace: fixed C5→E5 errors in multiple positions, fixed missing
G5 repeat, corrected phrase structure (was 31 notes, now correct 28)
- Greensleeves: fixed G3→Ab3 (G#3) at position 17 in the descending
phrase (B3,G#3 pattern should match the B3,G#3 at position 14-15)
- Deck the Halls: fixed B4→Bb4 at position 1 (key is F major, all B's
should be Bb except accidentals)
- When the Saints Go Marching In: removed duplicate F4 at index 25
(standard has F4 whole note then E4, not F4-F4-E4)
- Auld Lang Syne: removed extra G4 at position 9 that shifted all
subsequent notes, fixed garbled second half of verse
- Scarborough Fair: rewrote melody to correct register (standard melody
reaches D5/E5, game was stuck below C5), now matches lead sheet
Verified correct (no changes needed): Jingle Bells, Silent Night, Oh! Susanna

Old version had the Doo-dah phrase completely wrong (D E F E D C)
and a truncated chorus. Now matches the D-major lead sheet:
Verse: G G E G A G E C | D D (Doo-dah!) | E E F E D C | C(held)
Chorus: C E G G | G E G A G E C | G A B A G E | D D C(held)
Reduced passes 5→3 since the theme is now a full verse+chorus.

Tempo can't affect pre-scheduled audio mid-song; keep it in the
Settings card on the menu only. Volume slider remains in the game
controls bar as it affects live pad hits.
https://claude.ai/code/session_01DXp3FLfbb8jFHvCJ29uWk1
- endTurn now fires from draw loop once all notes are hit/missed and
past gameEndTime, instead of a tight fixed timeout; fallback setTimeout
extended to 5s so the music always finishes before scoring
- Double-click any rhythm button to immediately start the game with
current settings (delegated to rgrid to survive the onclick rebuild)
- Replace tiny 50px HUD sliders with a dedicated game-controls bar
below the HUD: wider sliders (140px), labelled Tempo / Volume with
live % readouts; syncSliders keeps both the menu and HUD in sync
https://claude.ai/code/session_01DXp3FLfbb8jFHvCJ29uWk1
Complete rewrite with new architecture:
- CONTINUOUS HARMONIC BED: sustained string/woodwind/bass chords
playing throughout all 88 seconds, changing with the harmony
progression (Cm→Ab→Gm→Cm→G→Cm). Not hittable — just ambiance.
- Running 8th-note string passages between melody sections
(background texture filling the spaces)
- 877 background nodes (was 565) creating a full orchestral sound
- 102 hittable melody notes (was 113) — only the STRONG accents
(motif hits, chord downbeats, scalar peaks)
- Duration extended from 54s to 88s (~1:27) ending at the natural
break where the exposition concludes before development
The player is now one voice IN the orchestra, hitting the famous
da-da-da-DUM moments while the full ensemble plays around them.
