Why it sounds like that

C bebop major adds A♭, the ♭6, to C major's seven notes. The added ♭6 creates a chromatic step between A and B, smoothing ascending lines. C major supplies the parent scale; the bebop variant keeps its major 3rd and major 7th.

When to use it

C bebop major fits C major and C 5th chords. Use it over C 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.
