Dave White

Currently accepting students of all levels on guitar and bass.

Dave White is a Camden County native and has been pursuing his passion for music since he was eleven years old. Starting on bass guitar, he later switched his attention to the electric and classical guitar - studying both popular and classical styles of music. 
 
Dave would obtain degrees in music from Camden County College in Blackwood, NJ, and a Bachelor’s of Music in Classical Guitar from Rowan University, graduating summa cum laude. 
 
After college, Dave performed first chair in the Philadelphia Classical Guitar Ensemble, and on weekends, performed at Ivan Kane’s Royal Jelly in Atlantic City, a nightclub featuring a vibrant rock n’ roll set.

From 2020 to mid-2022, Dave performed in Legacy band, one of Philadelphia's premiere top-40 bands. The band consists of former members of Don't Call Me Francis band and current members of John Legend and the Philly Pops. 

Dave has instructed guitar in community college, small businesses, and private households. He believes music is more than "just music”. He strives to help children and adults excel in confidence, critical thinking, and understanding music in both its physical & technical skill, and theoretical concepts. Dave dedicates his time to teaching students how to practice rather than expecting results through assignments. With Dave's guidance, students can see immediate improvement with focused, limited practice week-after-week. Watching his students build confidence in their skill is what makes him passionate about teaching the instrument.
