I started on keys, but was not any good. Immediately excelled at guitar, but I sold them as I discovered the Faith, since they were occasions of sin to me. I had been a hard rock/metal player for nearly a decade. Sold the bass also and the drums. I was no good on the drums. :barf:
I have recently considered getting another acoustic guitar, though. I think I could resist the temptation to "riff out". My fingertips would be pretty wimpy by now though, since I haven't played since early last year.
I sing Gregorian Chant when nobody's around - so almost never. I enjoy it much more than I ever enjoyed singing evil metal songs though and it's much easier on the throat - not to mention it feels incredibly natural.
I'm working on Dies Irae and next I believe it shall be St. Thomas' Pange Lingua.
