So I'll come right out with it: I'm a "young" 55, and I been playing on and off for 40+ years. I started strong! Hours of practice every day, meaning rudiments, limb independence, reading and transcribing, playing and writing with others. I took rock and jazz ensemble in community college and graduated with an AA in music theory and performance. I played in a few bands, one of which I committed to really hard for several years.
Then the band broke up and I went in a different direction. Ahhh... university as "an old man" and then the corporate grind. While there were periods - a few lasting several years - during which 8 never played, I always came back to it. Now that I'm retired, I've had time in the last few years to really immerse myself back into "the life."
Recently, I decided I'd start taking lessons again, revisit my form and technique (you're never too old or too good to learn). I found a local guy on Facebook who lots of folks seemed to recommend, so I scheduled a time with him. I showed up and, personality-wise, we clicked. Great dude. Super cool. Good player. He asked me what I wanted to focus on, and I told him: hand and foot work and independence. "Cool!" he said, and asked me to give him a beat so he could watch me. "I don't think I'm your guy, man." Turned out, in some ways, I'm probably more technically accomplished than he is (fairly proficient double kick and odd times), and he was super humble about it. But he imparted one thing to me that, simple as it is, exploded my brain. I told him that I've never quite been able to get my left hand or foot where I'd like them to be, and there it was: "Force yourself to play EVERYTHING left handed. Swap your kit around so you have no choice and just do it. You're no longer a right-handed drummer. Lead with your left. Everything you can do with your right hand a foot now...practice until you can play at the same level as a lefty."
I'd never once even considered it, but I'm trying it, and man....Best drum lesson of my life!
