C# Whole Tone, Piano Side
Where C# Whole Tone lies on this reader's keyboard, and what it is for.
6 notes to the octave, lit below across two octaves of this reader's keyboard, with every key numbered by where it sits in the scale. The numbers are the useful part mid-bar: a chart moves under you, and the thing you need is which degree is still under the hand — not where the run started.
Weightless and dreamlike — six equal whole steps with no leading tone, so nothing pulls anywhere. Blurry, floating, and faintly unsettling, like a dream sequence.
Heard in: Impressionist piano (Debussy's "Voiles"), Thelonious Monk's runs, dream-sequence film cues, and the augmented and 7#5 chords it fits in jazz.
The right hand takes the fill and the left keeps the written number sounding under it, so a piano reader hears every note of the scale against the chord the chart called rather than in place of it.
Run it hands together until the window stops being a pattern, then take it to a chart counted in C# and let the numbers pick their own notes out of it.
