D Whole Tone — Bass (4-String)

The D Whole Tone scale runs 6 notes per octave in the symmetric family. Below it sits on the Bass (4-String)'s EADG strings with every root marked, because a bassist reads a scale map as a set of targets around the root, not a row of dots.

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.

In fourths tuning every pattern is movable: learn the shape once, one finger per fret, and it works from any root on the EADG neck.

Walk it slowly against the audio, land each root on a downbeat, then take it to the progressions in D and let the scale turn into lines.
