Campo harmônico no violão

Knowing the harmonic field helps you get music faster

- This application was not made to address all existing harmonic field, nor something like that, I just want to show the smallest and largest natural harmonic field, which I find most important for those who want to learn to play music on the guitar.

- If you want to send an email to the developer, feel free. But be polite and treat us with respect, not everyone will like this app, this is a fact.

I liked this app and did you like it? Leave your opinion in the comments !!! : D
