Costly but also revolutionary
Response from developer
Well, not as expensive as guitars, but guitars get replaced, and skills stay with you and keep on growing. Thank you for your support, we are very glad that you took due advantage of this app. Our apps have the mission to share the passion for music and shorten the link between the musical thought and the instrument. A new similar piano jazz app is in the works. Also check out the newly updated Guitar Sight Reading app, not only it is a great way to learn written notes if you happen to not be fully fluent with them as many guitarists are, it is also yet another way to tie all the different shapes on the fretboard together
