Biography

Petrucci first played guitar at the age of eight when he noticed his sister (who was taking organ lessons at the time) was allowed to stay up past her bed time to practice. He soon dropped it when his plan failed. At age 12, he began playing again when he was invited into the band of his friend Kevin Moore, who would later become the first keyboardist of Dream Theater. Petrucci began to practice in earnest. He was a largely self-taught guitarist who developed his skills through attempts to match the skill of his idols, who included Steve Morse, Steve Howe, Steve Vai, Stevie Ray Vaughan, Al Di Meola, Alex Lifeson and Allan Holdsworth.
