Uh-oh!!!! I'm being forced (albeit gently) to write weekly small compositions (can I even call it that?) by my bass instructor! This week and last it's the 12 Bar Blues...Quarter notes only! Last week's was so dull I was only allowed to use notes in the chord (Chords Bb7, Eb7, F7). At least this week I can use passing tones. Any advice? This is a fun exercise, but I can't seem to make it work without going out of 'the rules'. We spent the main part of the lesson changing a lot of what I wrote. It was a very funny experience.
