hi, I have 8 years of experience in music, I can read notes and I also play the guitar and sing, I first learned to play the guitar by ear, but then I learned the notes, I also have some basic knowledge on piano and violin. I have tried teaching music to my 11 months old baby, who loves the harmonic and the guitar, as well as the drums. I'd love to participate in this beta testing. I'll be waiting for an answer. thanks!!!
