Maybe it's an idea to keep the length of the music down so we don't overwhelm the people new to classical music. It's too easy to be eager about all the music we love. The last 2 years I've taught music history in high school so I have some ideas on the topic. I thought it was very hard to pick the right pieces to use for learning more about listening skills and music theory. Next year we'll have a new curriculum, so I have to plan it all even better. Then I'll have to include world and folk music! Like if classical music isn't vast enough. After my 1st year I made a little poll based on a playlist of 33 pieces. The class favorite composers were Bach, Haydn, Beethoven, Schumann and Grieg.
