Going to a concert and doing nothing but taping the bass player. Obviously not for the whole concert, but maybe for a song or two. Unlike for guitarists and even drummers, there's a serious lack of videos on Youtube of just the bass player playing a song (videos like
this) unless their a famous solo artist. When analyzing someone's technique or how they play a song, I'm stuck with concert videos where I have to watch for a minute before getting a 3 second glimpse. When analyzing technique, I take a scientific approach. I learn the notes and tackle it my way, then see how the pro does, look at the differences, and see why he does what he does. Just get a feel for their style. Anyone done this?
