What is the most important thing when learning to play an instrument? It’s listening. Be it in private lessons or group lessons, at the harmonica school berlin we don’t just teach one technique, one genre or simply follow notation. If you want to learn to play the harmonica, you’ll be learning how to express yourself musically. You can learn to play the diatonic and chromatic harmonic, and additionally work in ensembles with guitar.
btw. Notation is definitely useful, but like language, you don’t need a script to speak.
