I've never never had a great ear, when I was young I was told I couldn't play the violin because my ear for tone wasn't good enough. I can't play by ear so sheet music & tabs are my friends. More recently I've been trying to work on my live improv by playing around with scales a bit. Some of you out there will have no idea why this is difficult at all. Congratulations, you're a genetically superior human being. For those of us who can't instantly tell what note is being played just by listening to it, we have to come up with other systems to remember. I've had this idea for a while now & I finally got round to pulling out my old bass & doing this: In case those cell phone pics aren't clear enough for you, I've just coloured in some little round stickers to colour-code all the whole notes. I've yet to find out if it works for me, but hopefully it will help with using scales up & down the neck. Luckily I had an old bass lying around, I'd be a bit embarrassed performing with something that looks like a Guitar Hero controller, but not too embarrassed to share it on the interwebs. Maybe this might help you or someone you know who is as retarded as me.
