I am a student at JNS and can attest to their world-class instructors. Their classes have moved online and there are several that are very complimentary to our studies here at PG. They will be held on the Zoom video conference platform which is very easy to use. The courses (improvisation, sole piano techniques, role of piano in combos, many more) will be live and interactive and you’ll receive feedback. There is tuition assistance available.
