The best overall adult piano book: Adult Piano Adventures All-In-One (Faber and Faber). It teaches the notes using interesting songs and moves at a good pace. Good for learning the basics and for moving on to classical or contemporary (i.e.. pop/rock) music. Best Piano Books For Adult Beginners Adult-All-In-One-Course. Check Current Price. This is one of my favorite books for adults as it is geared towards an older student.
