Josh is a rare, excellent teacher. First, I would mention his huge knowledge of music and instruments. Since he plays the guitar and the piano in addition to the chapman stick, he can apply knowledge from one instrument to the other, creating helpful metaphors for the experienced student. As for the inexperienced student, like me, he knows how to break down huge, intimidating concepts into bite size portions. He effortlessly comes up with metaphors and similes that really shed light on a variety of topics. This guy is a top notch teacher.
p.s. he's very patient too!
