Here is something to wet your appetite from an old friend:If you want specifically Beethoven, Bach and Mozart, you can start with those:1. Bach – The Little book of Anna Magdalena Bach of 1725 (ABRSM) – the 25 pieces in there are not really by Bach, but rather instructional pieces that Anna collected for her own instruction and the children.2. Bach – 18 Little preludes (Easier Piano Pieces no. 18 – ABRSM). Most of the pieces here are by Bach, but some are by his sons. They were used for the instruction of his children.3. Beethoven – A book of dances (Easier Piano Pieces no. 20)- Particularly delightful are the Six Ecossaises (to be played as a set) WoO 83 – they sound immeasurably more difficult than they actually are (Kissin plays them as encore).4. Mozart – The Nannerl notebook – Compiled by his father, Leopold this is a bit like the Little Notebook of A. M. Bach. There are sixty or so pieces from contemporary composers (most of them anonymous) and Leopold used it to teach Nanerl (Mozart’s sister the piano). Soon, Mozart was doing it as well, and the last 20 pieces or so are his own compositions (aged 4 –6).5. Mozart – 25 Early Pieces (Easier Piano Pieces no. 67) – Mozart’s first compositions, between the ages of 5 and 9.
