Hey, this is Mage , nationally certified teacher of music and business owner at Mage Music. I'm very happy with tonebase because, not only does it help myself as a teacher and performer, it also helps my students. So what I do is I recommend my piano and guitar students get tonebase, I'll even send them links to various lessons and resources so that they can actually benefit and improve and then we can discuss them during our lessons as well. It's an amazing resource for professionals and learners alike.
