I just turned 73. Worked on my '66 Corvette today replacing the spark plug wires--big job on these cars--and practiced bass, which I took up two years ago. MUCH harder for me, basically a bad rhythm guitar player, as bass is the same as lead guitar to me--you play every note, no strumming! Plus, small hands, short, bent pinky that doesn't stretch 6 frets, and the old arthritis...but I have always loved bass and wanted to be the bass player in all the bands I was in.
So, I took it up and it is hard and every time I get a song...even a simple one like These Arms of Mine...I really get a kick out of it. Now, if I could do Crazy Little Thing Called Love, I would be very happy, so will try that in a while as well. Tabs help, of course, and being able to read music is a help, but mostly, like the old joke says, practice, practice, practice. When I learn enough songs, I will get with some guys I know who are actually musicians and see how it goes for some fun.
I also bang on the drums some, and am bad at that as well, but enjoy remembering when I could almost play back in the day. Funny, the more I practice, the more I can do. I really wanted to be a musician, but did not get the genes, but I enjoy trying to play as much as I can.
Cheers!
