Playing and improvining fast 8th notes.

[Richard Prowse]

Bin,
I love that clip!
Both bassists are great!
The changes to Sweet Georgia Brown ((1st 16 bars (4 chords without the turn around) - any key)) are a good starting point for running 8th notes at fast tempos. Vary the tempos - from fast to slow/ slow to medium/medium to fast, etc. Also, try the 8th notes with a bow, it's actually easier! In my opinion 240bpm is a good median point to aim for at first. If you're playing those changes at different tempos, you'll probably discover that you are also exploring note possibilities almost by default. Try to make it fun - that never seems to hurt!
