At Seventeen was, and still is a huge hit for Janis Ian. She came onto the music scene as a 15-year old in 1967 with a somewhat controversial tune SocietyРІР‚в„ўs Child. In 1975 she was back on the charts with At Seventeen, from her album Between The Lines. The song features a gentle, light bossa nova feel with nice lines moving inside the chords. It is done with a capo at the 5^th fret and in recent years she has been playing it in a Dropped C Tuning. The lesson covers both arrangements.
