I recently found out how right you are, Frank. I made a big step forward about 6 months ago. Somebody in our song circle suggested that we sing softly enough that we could hear the different voices blend. I have always prided myself in the power of my voice, so it took me some effort (and humility) to quiet down a bit. It really has helped me - possibly the most important thing I've learned about music in ten years.
