Aebersold Book 1........ I read through all the material at the front of the book a few times. It made perfect sense. I was overjoyed - couldn't wait to get started. Then I started. Urf...... Right now I'm working on trying to play along with the first track on the cd, which is 3 different keys (chords?), 8 bars each, repeated 3-4 times. About all I can do is play ascending whole and half notes in order to keep time and not miss the key changes. Somewhere in there, I start over-blowing, and my embouchure goes to heck, and I take a break and start over. Basically, I struggle to stay in time and not get lost, which requires 397% of my concentration, so doing anything creative is out of the question, especially when I keep over-blowing freakin' C on the staff. I'm assuming that over time this gets easier? Yesterday on my evening commute, I popped the cd in, and started just buzzing my mouthpiece along with it, keeping time, and changing tones when the key changes came around. I managed to keep time pretty well that way, but it was about as melodic as fingernails on chalkboard. Input? Anyone? The kid who posted his video on here the other day is an Improv God compared to me.
