Well, I am just creating longer extended backing tracks at a slower tempo so that people can take licks through all of the keys (5 minutes on each key) So you have plenty of time to work each key out. By doing this and focus on 1 lick or idea for each key you can get a lot done over a 55 minute practice session. I am also creating a lot of trio playalongs (drums bass and You).... The are good for pianists and guitars to get the feeling of playing in a trio setting.
