Gibson L-5 ,

excellent theory and practice

Like the app for the Minor ii-v progression, this is one of the best apps I have seen for jazz theory and practice. I like how the developer has isolated a useful element in jazz improv, provided clear explanations and examples, and then also provided audio examples and backing tracks. The app provides good practice advice for how to learn and implement the improv skills in the app. This is a serious jazz educational tool created by someone who is obviously a working jazz musician/educator. Highly recommended.

Very impressive

This app has more bang for your buck than the low price suggests. After getting through the intro and listening closely to Miles Davis "so what", every scale and except side can to life with the jam-a-longs....

My only (minor) complaint is the younger generation user "small" font that only kids can
(iPad for me next)
Hopefully they can do a small EQ to take out bass to just hear piano, no drums, etc....
