There are four basic Lesson Books and Work Books in the series along with four accompaniment CD’s. Other options are also available to purchase, including flash cards, soft toys, Music Discovery books and Recital Books. Each level of Music for Little Mozarts has two accompaniment CD’s. One is for the Lesson Book and one is for the Discovery Book. Each song in the lesson book has its own accompaniment. A piano accompaniment is written in the students’ book for the teacher to play along with, making each song a delightful duet. Students also play along with the CD which gives the correct timing and a professional sounding backing. Learning the piano is accelerated by regular use of the CD both at lesson and at home.
