I was wondering. I have been playing music for several years and have played in a handful of bands, both cover and original. My technique, composing skills, music theory knowledge, playing skills, and all that other good stuff has gotten 100 times better than when I started. But, I cannot play any better or worse by ear than I could many years ago? Why is this? I cannot tell one chord from the other on guitar without being told or getting lucky. I can't even tune my bass by ear either. Am I tone deaf? I really think so.
