Why it sounds like that
G bebop major adds E♭, the ♭6, to G major's seven notes. The added ♭6 creates a chromatic step between E and F♯, smoothing ascending lines. G major supplies the parent scale; the bebop variant keeps its major 3rd and major 7th.
When to use it
G bebop major fits G major and G 5th chords. Use it over G major progressions in jazz and swing. The ♭6 works as a passing tone to the 6th or 7th.
Which position to practise
Practise Box 1 first. It keeps the root under your first finger and covers frets 0–3 for quick two-octave runs.
