iImprov-Modal is the 2nd release from Jazz Apps Mobile LLC. It is part of a series created for jazz musicians of all levels to help them take on specific challenges that any improvising musician will encounter. Each one contains a full explanation of all the concepts and theory involved as well as written and audio examples and exercises. Each app contains JAM-A-longs in all keys with adjustable tempo and control of instrument balance. Each iImprov app also allows you to select the correct transposition for your instrument.

Ratings and Reviews

I've been a musician most of my life but have always been intimidated by Jazz, perhaps because I could not understand it. This app explains the theory very clearly, how chords relate to scales/modes, and the exercises within are well structured. The backing tracks sound great and are fun to play along with. I strongly recommend this app for all musicians!

Not even remotely worth the money...


Not a bad interface but extremely limited information for £2.99. You could get this info for free from the Internet and use the iRealB app as a play along mechanism. Unfortunately very disappointed :(



I love these apps. When will we get some more! They're really useful for practicing. Thanks, developers!
