Piano Fills With C# Whole Tone

Where C# Whole Tone lies on the piano's keyboard, and the fill it feeds.

C# Whole Tone runs 6 notes to the octave. Below it is lit across two octaves of this chair's keyboard with every key numbered by degree, because what a fill needs mid-song is not the run — it is which degree the right hand is sitting on when the chord changes under it.

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.

A piano fill lives in the right hand over a left hand that never stops comping, so the scale is read two ways at once — which notes sing over the held chord, and which ones walk the song into its turnaround.

Work it over a held left-hand chord until the right hand stops thinking about the order, then take it to a song in C# and let the melody choose which notes the fill keeps.
