Playing with bounce
'Bounce' or 'swing' is a rhythmic approach. The same notes played with or without bounce sound very different. If you want it to sound like Bill, play it like Bill, with bounce.
The Circle of Fifths
There is a logic why certain chord sequences sound good. Bill loved to talk about the Circle of Fifths for hours. Here's a condensed of about 10 minutes.
Pentatonic scales
Pentatonic scales have only 5 notes. They are easier to play than full scales and they often sound better. Learn to play melodic lines that fit very well chords as G, C, F and Bb, but also Em, Am, Dm and Gm and more.
The 9th chord
You would think about the 9th chord as something used in jazz only. Bill would tastefully spice up his solos and backup in 3 chords songs (G C D) with jazzy chords. In this video, I'll show some examples of how he used the 9th chord.
