Each student will learn to read music and know all of the key signatures, time signatures and accidentals (sharps, flats, how the music is to be played), within a very short time. It all depends on the student as to how fast you can become a great player...It's all about practice!
I teach Classical violin, Cape Breton fiddle tunes, Bluegrass. Country and some blues and a bit of jazz. You can intermingle your choices in order to learn the various types of music you want to play.
