I know today was filled with way more info than usual, but it was a good start. Please review that stuff with your teachers. Here's what you need to do this week. Pick one Beatles song, write out the chords, figure out the key and make sure you know which chords are interesting for some reason (they could modulate to another key, add some uncommon harmony, or even be voiced in an unexpected way).
Drummers should pick one Motown song and study where the fills and cymbal crashes are. Are they during an important line? End of a solo? Why were they played?!
Next Wednesday we'll take a look at the progressions you wrote tonight and attempt to build upon or tinker with them.
Also, you should start keeping notes of interesting riffs, melodies, progressions, and lyrical ideas. Keep a log of that stuff for easy access.
