About four years ago, I was in a beginning orchestra class playing the upright bass. I got a bass guitar around that time, but couldn't figure out how to relate the notes to the upright bass. All those frets were confusing me! So I gave up on the guitar, which was a big mistake. I've gotten a beginning bass guitar book and I now know all that. So I was wondering if anyone could briefly compare and contrast bass guitar and upright bass? My true love is still the upright, but guitar is great too. Oh! And how does one go about learning to tune by ear? Before I found my tuner, I did my best by playing songs I knew and tuning to how I thought they should sound. I was pretty close with two strings, but I found it very difficult. Any advice?
