Hello, I've only just begun learning the bass (started exercising about 3 weeks ago), I've been mostly absorbing YouTube lessons and in the process devised my own simple exercises. It's my first musical instrument. Recently I've started training with a metronome, starting from 70 BPM and doing this: - Starting with the lowest string (G) I'm playing from the 3rd fret to the 12th and then go backwards to the 3rd fret again. I repeat this 3 times and then switch to a higher tempo (90 BPM) and once again to the 160 BPM. - After that I simply go up a string and repeat the same process. I have a couple of questions: 1) Is that a good exercise at all? I've been noticing improvement over the weeks, I had problems playing with metronome but now I can match the tempi (70, 90, 160 BPM) nearly effortlessly so there's some progress, 2) However, trouble begins with the E string - my plucking hand tires quickly (I have my thumb rested on the pickguard above) and my fretting hand movement is...clumsy, to say the least. Is that normal? Would appreciate pointers I'm playing on an American Standard Precision Bass.
