In this class you will understand how the blues harmony basis works, that is, what instruments like guitar, piano and guitar do during music. It is important for us, as harmonica players, to understand what is happening in music, so that we can get the best out of the instrument, and thus know what scales and notes we can use. Through practical examples, exercises and phrases over the degrees of the blues progression, you will be able to understand these concepts, but if you want to go deeper into this subject, just watch the theoretical part of this class.
