Recently I decided to educate myself a little more on classical forms. I always felt a bit lost when I tried to compose something that was supposed to be a formal piece, realising that I was to unsure about what the rules actually were.
I discovered this video that is part of a series of Leonard Bernstein teaching us how to listen to classical music. The series on the sonata form is for kids and crystal clear (and a bit simple). It consists of four parts, so you can continue to the next part after finishing this one. I will soon post some other episodes of the same series. His introductions of composers are some of the best I’ve ever encountered. Enjoy!
