All of this semester, I've been very dilligent about practicing everyday in order to inrease my 16th note chromatic speeds. However, today I realized I might be running into a problem. When I practice, I practice to a drum machine which plays a kick drum on every beat and a cowbell-type sound on every 16th note. I'll play a bunch of chromatic scales going all the way up the neck while keeping time to this beat. Today I tried to do it without the 16th notes in the beat to keep track, and here's where the problem comes in. When I play at the upper limit of my speed exercises, my 16th notes come off with a kind of swing timing to them. If I concentrate I can get them to be straight 16th notes but it's difficult. I'm wondering if I should start practicing without the 16th notes on the drum machine so I can pay more attention to the spacing of my 16th notes? The whole reason why I practice to the beat with 16th notes was to get better timing with my 16th notes in the first place. Has anybody else run into this kind of problem?
