You just learned a new tune and you play it over and over in your living room when no one is home. Each time you play it, it gets better and better. At some point it sounds so good that you think of quitting your day job and taking it on the road. You envision yourself touring with your favorite band.
The tune is that good. And your playing of it, is that superb.
You then hit the session that week and decide to start that very same tune. You gather up your courage and step up into the silence to play the first note. Suddenly you can’t remember the rest of the tune. That tune you just quit your job for and became a rock star with suddenly is lost in the abyss of your brain and you start to panic.
After the freak-out passes, you eventually do get through the tune though it doesn’t sound anything like the monumental piece you practiced in your living room all week. (Thank God you didn’t really quit your day job).
This does happen to you, right?
