My daughter is much more inspired to play with this piano method than she was with the first one we used by a modern publisher.
Unlike modern piano methods, which write their own original yet uninspiring music, this collection of easy childrens' pieces is by the classical MASTERS and are melodic and FUN to play.
If you want to go further into these pieces, buy the original collections such as Robert Schumann's book for Children, Bach's collections of firsts, Tchaikovsky's, Gurlitt's, Czerny's etc.
I never realized that so many of these famous classical composers actually had works that they wrote FOR children. Suzuki is simply a compilation of them. Don't limit yourself to just this collection, but these are so great to learn the basic rythms, chords and easy melodies.
