Most people agree that picking up new skills enriches your life, but fitting the associated time commitments into an already full schedule is usually another, bleaker story. That's why Philadelphia Guitar Instruction owner Billy Redfield cuts a surprising obstacle out of his lessons: the practice space itself. His 30-minute guitar lessons take place the comfort of clients' homes, helping them squeeze in guitar practice between obligations to work, family, and ongoing games of Jenga. Accustomed to working with students of all ages and ability levels, Redfield tailors classes to cover only the most important skills, from learning chords and reading guitar tabulature to restringing and tuning the guitars themselves.
