Andrew Horowitz, Pianist

Teacher, Accompanist, Performer


I have been teaching students in Northern Virginia to love music and play the piano with confidence since 2000. A desire to increase the professionalism and quality of my teaching led me to open my own independent teaching Studio in 2008. I wanted a space where dedicated teachers and interested students could do serious work but also have fun. A space where young beginners, advancing teens, and adults could all feel comfortable and at home. And, a place where where all students and all teachers have the opportunity gather together for group classes and recitals.

My goal in short is to take interested and eager students of all ages and to give them the skills that will allow them to make music, and to listen critically and thoughtfully, long after their formal lessons have ended.

A sought-after teacher, pianist Andrew Horowitz, NCTM, is also active as a soloist and accompanist. He holds a Bachelor of Music degree in piano performance from George Mason University. Teachers include Dr. Joanne Haroutounian, Dr. Robert Wyatt, and the late Andrew DeGrado.
