Sleep Stage 3B
[Intro] [68 BPM; use only F G A B C D E] [begin with F as the tonal center] [soft piano states F-A-B-A over a warm F-centered voicing] [rounded low pulse moves evenly underneath] [very soft muted rim appears only in the opening] [Instrumental] [piano stretches F-A-B-A and leaves longer rests] [answer with A-G-F] [keep F in the bass while D becomes more present in inner voices] [muted rim becomes sparse] [Instrumental] [piano reduces the motif to F-A-B] [alternate F and D gently in the bass without an obvious modulation] [sustained harmony gives D-A-F more weight] [keep the pulse rounded and unaccented] [Interlude] [piano rests] [muted rim disappears] [sustain F-D-A with slow smooth voice leading] [let F and D feel balanced rather than resolved] [keep the sustained tone clean and stable] [Instrumental] [piano states F-A-B-A once] [the next phrase uses F-A-B and ends on D] [bass returns briefly to F, then settles toward D] [keep the transition gradual and understated] [Instrumental] [piano uses F-A-B with longer note values] [D remains under more phrase endings] [sustained voicings move slowly between D-A-F and D-A-B] [pulse remains steady while event density decreases] [Interlude] [piano leaves a wider silence] [sustain D-A-F with occasional B natural as a gentle upper color] [let the clean sustained harmony carry the space] [do not introduce new melodic material] [Instrumental] [piano reduces to F-A] [D stays in the bass] [use smooth inner-voice movement between D-A-F and D-A-B] [avoid a strong cadence or dramatic key-change gesture] [Instrumental] [piano plays F, A, and B as separated tones rather than a full motif] [each short phrase settles toward D] [let longer decays fill the spaces] [pulse onset softens slightly] [Interlude] [piano rests] [open D-A and D-A-F voicings carry the harmony] [pulse stays soft and predictable] [harmonic changes become less frequent] [Instrumental] [piano plays F-A once, then isolated A after a long gap] [D remains the resting point] [no full F-A-B-A motif returns] [keep the music connected through sustained tone rather than rhythm] [Outro] [piano plays isolated A, then D] [sustain D-A-F underneath] [rounded pulse softens beneath the final decay] [clean natural ending] [End]
