I'm really not bragging but I've learned how to play so many songs over the years that it would take me hours to come up with a complete list. Pretty much anything you ever heard on the radio from 1975 until now I've taken a swing at on guitar, piano, sax and/or bass guitar. Call it the musical baggage of being just this side of 60
What's your breakdown in terms of "time playing"? Meaning, in any given day or week, how much is guitar, how much is piano, how much is bass.... not talking recording, just playing. (Does this make sense? I'm basically going for, if you're going to pick up an instrument what is it most likely to be)?
I consider guitar to be my main instrument, but I was determined to learn piano correctly so about 5 years ago I took about 1 year of professional lessons, brushed up on my very long-dormant music reading chops and actually learned how to play the piano correctly. Today I can pick up a song like "Piano Man" by Billy Joel or "Come Sail Away" by Styx in a few hours and be able to play them through without any major mistakes with maybe a week of practice. Learning the piano was the best thing I ever did for myself in terms of really digging into music theory and learning more about how to actually leverage some of what I learned and put it to practical use on my group's next album.
That said, as of this writing I can competently play clarinet, saxophone (any size, but I prefer tenor), trumpet, piano, guitar, mandolin and bass guitar and I've been dabbling in a bit of harmonica lately on a blues album I'm working on. I don't have any plans to learn any more instruments, but I am playing every one of these on the album as well as a traditional Navaho Pan flute I bought on a reservation in Arizona back in the 00's.
But even though I started with the clarinet in 1973 and stayed with wind instruments all the way through primary education, I was always infatuated with the guitar because of my father playing it in his band, which I got to watch rehearsing every night in our basement when I was a kid, you know, back before we had electricity and indoor plumbing.
