Ab whole tone scale positions on guitar — all 6

Ab whole tone fits in a five-fret box, three notes or two on each string. Every step in the scale is a whole step, so all six positions are one shape: move it two frets up or down and you have the same six notes again, anywhere between frets 0 and 14.

Chords to play Ab whole tone over

Ab whole tone is the scale for the augmented chord Abaug (Ab C E) and for Ab7#5 (Ab C E Gb), a dominant 7th with a raised 5th. Every note is a whole step from the next, so the scale has no perfect 5th and no half step to resolve by, which is where its floating sound comes from. It is two augmented triads a whole step apart, Abaug and Bbaug.

Play the Abaug arpeggio inside the scale → The Practice Loop keeps only the chord’s notes in each position, so you hear what the rest of the scale is decorating.

How to practice the Ab whole tone scale

  1. Start with position 5 at frets 0–4, slowly, until every note lands on the click. The loop keeps the shape and the tempo for you.
  2. Slide the shape: position 6 is the same fingering 2 frets higher, and the same notes. Play one, then the other, and the move is the scale.
  3. Climb 3 notes at a time, one note up each time: each group starts a whole step above the last, the same step the scale repeats by.
  4. Switch the same position to the Abaug arpeggio, the chord’s notes alone, then back to the scale.
  5. See every Ab whole tone note across the whole neck on the Fretboard, and find each box again an octave up.
