Been thinking about the OP’s question. It might be that you can judge your level of commitment by the number of calls you get.
Face it; if you aren’t getting many calls, you’re probably not committed enough to work hard enough to learn the skills needed to become an in-demand musician.
From the posts I read here, most musicians play guitar. Most can’t read music and don’t have much understanding of music theory. Most can play a few chords in a very few keys.
My point: You can find musicians like that behind every blade of grass. Who’s going to call you if you aren’t demonstrating the commitment necessary to learn your art? What makes you stand out among all the other garage-band guitar players?
One of the bands I play in is a 17 piece jazz band. We normally start off a gig with the leader saying, “Okay, let’s play a blues in F”. Or it might be in Bb or Eb or C or Ab or whatever he feels like. The rhythm section starts off and everyone takes a ride. All the musicians know the standard blues changes in every key, so it’s no problem. Those guys and girls have paid their dues by learning their craft. If they can’t cut it, they don’t get asked back and the word gets around that they can’t play. They don’t get any more calls.
BTW, our guitar player is phenomenal! His solos will knock your freaking socks off!
So, what’s your level of commitment? Do your skills make you special, or are you just another guitar hack?
