Through it you can develop the ability to respond to high speeds and accurately on the chords of any progression or Jazz Standard.

Your brain will be stimulated to respond with speed to any harmonic situation (you would be playing the essence of composition of all Jazz Standards that exist).

Visual and verbal familiarization of chords in different environment or random allows to gain advantage when making decisions while improvising, allowing the improviser musician to focus on time and expression.

Without a doubt, the best virtual improvisation coach in his class.

Do not purchase this app! The description appears to an articulate description of a training program, in reality this is an excessively overpriced piece of junk that does not work! The help website instructions are not in English, which would not change anything. No direct access available to communicate with the developer! I’m trying to obtain a refund, this app should be removed from the App Store. At best it’s an inept representation at worse it’s potentially a fraudulent scheme, a wolf in sheeps clothing!

Unfortunately we cannot provide negative scores, this deserves a -5! Hope others will bypass this mediocre product! You can do far better for 99 cents!

Thanks for your review. We regret your bad experience with our app, the app has been redesigned, but under the same approach, the teaching, practice and mastery of the chords (as described in the description). It is not a theft or fraudulent product, perhaps you did not understand the focus of this tool. We wish you good luck with the new version!
