Highly recommend to all new to music theory

This is a fantastic app : comprehensive in its breath of scales, modes, chords, and all illustrated on the circle of fifth ! The audio to play the chords and arpeggios is not working however.

Response from developer

Hi, Glad you like the app. In the menu (3 lines) you need to choose for an instrument first. I bet you will hear some sound. Let me know if that works for you. There’s also a help available in the menu.

wrong notation

seems pretty interesting, if in the chord and arpeggios the notes on the lines were correct. C appears as B. can this be fixed?

Response from developer

Maybe you have chosen the C clef for piano or the viola? If not, maybe you can send me a screenshot? info@guitarapps.nl
