I heard this a while back in a business context and it stuck with me. And from my experience, it’s been true. But what does that mean for those of us who play multiple instruments? The three that I play are double bass, electric bass, and piano. And if I had to rank them in order of importance to me, I would place them in that order. I’m learning piano in the context of a degree I am pursuing which requires a certain number of credits in keyboard competency. I also use piano for composition, which at this point is just limited to school assignments. Next is electric bass, which was my first instrument, and which I still love to play. I’m in a Soul band and that’s my highest profile gig at the moment and the source of most gigs I do. Lastly, and perhaps most importantly is double bass. I’m pursuing a BFA in jazz bass, but I’m also a big fan of orchestral and classical music, and the repertoire possibilities that the double bass affords. So, my question for those of you still reading is, do you ever feel that playing multiple instruments means that you are taking away focus and proficiency on a single instrument? If I spent all my practice time on double bass, might my technique might be better? For reference, in 2018, I all but closeted my electric basses and just focused on upright. That definitely pushed me forward on the instrument. These days, I love both, and I want to improve on both. Perhaps playing multiple instruments at a reasonable level of proficiency is on balance a better approach than focusing on one for a slightly better ability. I want to be able to play cello repertoire on the bass and be able to join an (community-level) orchestra. I also want to be able to solo like Willie Weeks on the Fender. In other words, I want my cake and to be able to eat it too. Who can relate?
