Bill Pernice, Lead Music Teacher and Music Program Coordinator



Bill’s passion for music began as a child when he was offered piano lessons at the age of four.  He trained and performed classically and studied music education at SUNY Fredonia.  Eventually the creative and improvisational genre of jazz offered an immersion into the satisfying complexity of deep listening, technique and co-operative musicality in the present moment, an art form that Bill’s classical roots have built upon and that he brings to his students and his performances.  Bill has conducted, composed, arranged and performed music for orchestra, band, chorus, theater and individual performers in various music styles.

Bill began his career in Waldorf education by accident when he volunteered to assist in his son’s preschool.  He holds a teaching certificate in Waldorf Education from Sunbridge College.  Bill was the founding teacher at Dayspring Community School in Warwick, NY and taught kindergarten there for four years.  Bill went on to teach both instrumental and choral music to students at Green Meadow Waldorf       School for 18 years.  He worked as Development Director for three years and Pedagogical Administrator for four years at Green Meadow and then returned to teaching music there until last year. Bill has served  in ASWNA and NYSIAS, community renewal and inclusion-based group work, as well as consulting for developing Waldorf Schools.

Bill has a passion for helping students to find joy, creative thinking and connection for themselves and with others through music.  In his spare time you can find Bill reading, writing music, doing yoga, hiking and traveling with his wife, Kate and playing jazz gigs. He has two sons who are Waldorf school grads.
