I've had several occasions recently where I've felt frustrated, either by deleted comments or by closed threads (others, not my own). Although I have a music degree (theory major) and a lot I'd like to discuss, or even to teach, I kind of feel I can't breathe here sometimes.
A recent example was a question where someone asked how to modulate between C major and e-flat minor. I could think of a few interesting ways to do that, and felt it would be worth a cup of coffee and 30 minutes of my time to discuss equal octave division, relative keys and so on in this particular case. Instead, I came back to find the thread already closed with a link to a HUGE thread on every modulation technique under the sun. If that's the practice, why not just answer every single theory question with a link to Wikipedia?
I felt quite disappointed, because I felt I'd lost a chance to contribute what I felt were some interesting ideas. And I can only imagine that the person who wrote the question felt even worse.
Monica in Friends famously shouted, "But. . . rules help CONTROL the fun!" I disagree. I come to a forum for free interchange of ideas, not to feel like I've accepted a 2nd job and the boss is always looking over my should to see if I'm "doing it right." Can we maybe chill out a little and let people breathe?
