Bass Fills With F# Whole Tone
Where F# Whole Tone lies on Bass's fretboard, and the fill it feeds.
F# Whole Tone runs 6 notes to the octave. Below it is laid onto this chair's EADG fretboard with every F# marked, because what a fill needs mid-song is not the pattern — it is where the root is 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.
The bass rarely takes a fill, and that is precisely why these matter: the notes between one root and the next come out of the scale, and a walk that lands wrong is the loudest mistake in the mix.
Play it slowly against the audio until the shape stops being a shape, then take it to a song in F# and let the melody pick its own notes out of it.
