Sleep Stage 1B
[Intro] [76 BPM; F Lydian; use F G A B C D E] [soft piano introduces F-A-B-A over a warm F-centered voicing] [rounded low pulse establishes an even calm groove] [very soft muted rim gives light backbeat support] [leave clear space after each piano phrase] [Instrumental] [piano repeats F-A-B-A, then answers with A-G-F] [keep F in the bass while B natural adds gentle Lydian color] [connect the phrases with smooth inner-voice motion] [do not turn the motif into a rhythmic hook] [Instrumental] [piano moves the motif one register higher, then returns lower] [harmony opens around F with C and G above the bass] [upper-air synth widens slightly without becoming brighter] [groove remains soft and unhurried] [Interlude] [piano rests for a longer span] [sustained harmony carries F-A-C-B with slow voice leading] [rounded pulse continues evenly beneath the hold] [muted rim becomes less frequent] [Instrumental] [piano returns with F-A-B-A, followed by a longer F-A-B-A-G-F phrase] [keep the melody legato and low-velocity] [harmony moves away from F briefly and settles back without a strong cadence] [Instrumental] [piano phrases lengthen while rests between them also grow] [muted rim becomes sparse] [use small melodic changes around F-A-B-A rather than new themes] [keep B natural soft and brief] [Interlude] [piano leaves space while the sustained bed carries the harmony] [low pulse remains the main rhythmic reference] [upper-air texture stays smooth and diffuse] [harmonic motion slows] [Instrumental] [piano states F-A-B-A once, then answers with G-F after a pause] [simplify the voicing toward F-A-C with B as suspended color] [keep the musical line connected, not looped] [Instrumental] [piano uses only fragments F-A-B and A-G-F] [muted rim nearly disappears] [let longer decays fill the gaps] [maintain F as an unmistakable resting point] [Interlude] [piano rests] [sustained F-centered harmony changes only through gentle inner voices] [pulse softens slightly but remains countable] [upper-air texture begins to recede] [Instrumental] [piano returns with one slow F-A-B-A statement] [follow with a small A-G-F answer and then leave space] [no new melodic material] [energy stays level while event density decreases] [Outro] [piano gives one quiet F-A-B-A statement] [sustain a spacious F-centered voicing underneath] [rounded pulse softens beneath the final piano decay] [upper-air texture recedes] [clean natural ending] [End]
