would love to know how many are you that are writing for a living... writing/producing for tv and film are actually guitar players. im not talking about many of you who can ALSO "play" the guitar. Those of you who guitar is your main (instrument you have studied) instrument.
-has your keyboard chops improved over the years?
-do you write your stuff on guitar first or simply on paper?
I'm a guitarist. It's my main instrument, although I also studied piano as a kid, and kept it up as the years went on.
I was a jazz guitar major at North Texas State in the early 80's, and studied some piano there as well.
I don't work in film or TV, but record production. My "skills" as a keyboardist allow me to do more on the records I produce, and it also brings in other types of work that I wouldn't get as a guitarist alone.
Guitar is my main instrument, and though I prefer to be thought of as a composer, it can be very financially lucrative to be known for guitar. Once people know you can read music and play classical, gigs seem to line up (for me, anyway). And there are always new students wanting to learn guitar.
My keyboard chops remain woefully mediocre, but it's something I'm working on improving.
I usually begin writing by turning off the computer and improvising on the piano until I stir up ideas. This occassionally works on guitar, especially when I'm writing for solo strings (the guitar strangely helped a lot when writing a cello piece last year), but piano is the usual way to go.
