# helpabeach — mysterious-exploration chillwave / ambient (~2:30).
#
# Key: A minor pentatonic (A C D E G) + a single F# leading tone in
# drift 2 / undertow for tension before resolution.
#
# Tempo: 84 BPM. Each *N is a beat (60/84 ≈ 0.714s).
# Eighth-note ≈ *0.5; quarter = *1; half = *2; whole = *4; sustain = *6+.
#
# Notation extension: chord tokens are notes joined by `+`, sharing
# one weight. Example: A4+C5+E5:_*2  →  A-minor triad held for 2 beats.
#
# Section markers gate which bed layers fire (waves / sweeps / shakers
# / kick / bubbles / birds / pad / bells). Held / structural notes
# (durSec ≥ ~1.4s) also trigger the sub-octave DEEP bells.
#
# Narrative arc (instrumental — voice enters only as a faint texture
# from deep-current, never in the opening):
#   tide-in      — pure ocean, descending breath, low and slow, no bells
#   drift 1      — climbing single line, ramping rhythmic density
#   swell 1      — first peak: chord triads on downbeats
#   deep-current — NEW: slow low register, deep bells surface
#   drift 2      — climbing line, F# leading-tone tension
#   undertow     — NEW: deepest/darkest, octave-down, pulled-under
#   swell 2      — NEW: return peak, brighter, fuller chords
#   tide-out     — resolution: ascending tonic flourish → big held Am
#   ebb          — NEW: long ambient outro, low notes dissolving out
