As I've spoken with several players recently, I always bring up my experiences singing with the church choir...I would always get a kick out of centering my voice's pitches with the organ and feeling the resonance. I would listen to the others sing, and it was often that they would be either sharp or flat with respect to the same organ, and it was not pleasant for me to hear myself or the others when our intonation was off. If I was off, I would hear it immediately and adjust my pitch. I also perceive intonation problems when I hear others play the bass without accompaniment and when I listen to recordings of myself practicing. But when I'm actually practicing the bass I'm just not hearing it and adjusting as I play often enough for comfort, and this frustrates me. Open strings are not very forgiving to poorly intonated stopped notes. Did any of you have this problem as you were developing, and if so, how long did it take for you to improve your ability to correct your intonation just by listening to yourself? I enjoy hearing and feeling my bass resonate when my intonation is good, but is there more for me to go with than my same experience with that church organ?
