With the help of a fellow homeschooling mom, who has a background in music, I've selected a composer for each month, mainly in chronological order:
Bach
Handel
Mozart
Beethoven
Schubert
Brahms
Wagner
Strauss
Stravinsky
She wisely suggested including pieces of different types (piano, symphony, etc.) because otherwise it can all start to sound the same. Karen Andreola
We happen to have an extensive collection of Bach, as he is probably my favorite composer. I also requested a couple of CDs from the library. Each day, during our playtime, I'll play one on random. If the kids ask, I'll tell them the name of the composer and the name of the piece, but I don't intend for them to memorize anything. My goal is to develop a familiarity with the music, which will hopefully encourage a greater enjoyment as they grow.
