This collection contains 33 pieces written for piano. Most people refer to the popular composers like Mozart or Beethoven but in this collection you will find names like Kuhnau, Häßler or Gurlitt, which - at least for me - were unknown before.
The quality of the arrangements is very nice, i.e. clear written, good fingering and easy to read. If you are just a beginner, you might better buy another book, since this arrangements are for intermediate players.
You can download every piece played by Aki Sakae at you want to find out about the music contained in this book, you might listen before. For me, even just listening to these recordings is already enjoyable, so have fun!
