TLH21 a teacher used to play us pieces on the piano then explain what they were all about.
My experience with music at school was actually the complete opposite. At elementary school we were taught musical theory without any context. Dots with silly tails on lines, it made no sense at all. Fast forward to high school and our music teacher would bring in her record player and stick on say a Mantovani album, and play it to 15 year old boys who were into the Beatles or Rolling Stones, to 'educate' us in 'real' music. We weren't the slightest bit interested, and so learnt nothing.
A few years later, in a shared house with someone who played guitar, my musical journey started.
