At the age at which most children learn to speak, Mozart had already composed four symphonies, restored 11 classic cars, and built a robot to play him in squash. Catch up to Mozart's accomplishments with today's Groupon: for $37, you get four 30-minute private music lessons at Rustic Music Center's two Staten Island locations on Richmond Road and Forest Avenue (up to an $85 value). This deal is valid for lessons in guitar, piano, drums, violin, viola, flute, sax, and clarinet. For 45 years, Rustic Music Center has taught the city's budding tune virtuosos how to read music, master a new instrument, or twirl drumsticks while playing to produce a hurricane of harmony. If you don't have your own instrument, you can borrow one of the in-house instruments as an experienced instructor guides you along the rocky star road to rock stardom.
