John - maybe one reason I bring up singing is your user name!
Did you take lessons, play in band, orchestra, both? As an adult, are there such groups to play with? As far as scoring: do it! No matter or not if you think it'll be heard. That's great. Have you manually written any scores? It reminds me of Finn, that kind of composing, he says he has many themes, and I think chooses from these to build a song.
I played alto and tenor for a while as a child but my bottom lip couldn't hack it. Being in or around woodwind and esp. string sections, in my case, it was like osmosis. You don't think it gets in you at the time,
but it does. Since you were focusing (it sounds like), a lot must've gotten in you.
That clipping thing - I don't have any suggestion but turn away or back up from the mic, lol. One song, I was practically in the next room, didn't matter. Kept the piercing chorus, it fit the song, but wouldn't on O Holy Night!
I wonder if you'd like this book I'm reading "Inside Tracks" (I'm sure the engineers like Bong and Prometheus would). It's engineer/producers speaking about recording, but many of these are musicians or writers, too. About every few pages, the engineer/producer in question brings up performance, sincerity (re: O Holy Night - dry but sincere). Very few (if any) emphasize production per se. It's been a great confirmation to do what I think in the first place: try to get a good track singing or drumming or whatever-wise. Which is not what I expected - I wanted the technicals. But they're artists, just artistic in knowing rooms and micing and boards as well.
