I played Trombone for 10 years, but haven't touched it in several years. Therefore I chose "Other horn". But I would like to have seen another choice: Tech Support. Music and Performance Tech Support, that is. :) I contend that interpreting the sound of a band and singers, and deciding how the audience will hear that sound, is musical. I hope that the following provides evidence for my claim.

I am one of the media techs at church, so I get the band set up for our weekend services. (I'm the sound tech for the Saturday evening service, which is the first of 3 services for the weekend; I basically have to get everything set up correctly.) The band (and Music Pastor, and Worship Leader, and Senior Pastor) rely on me to balance the instruments and the vocalists, to ensure that every solo is heard, to balance the sensitive ears of our older memebers with the appreciation of volume our younger members and young guests have, and to ensure that every speaker and interviewee is heard.

The job is quite musical, though I don't make claims to be a musician based on my tech experience. :)

. . . Wow, it seems I'm a smug and self-important smart-guy. I don't mean to brag or make myself into more than I am. I just wanted to make the point that I'm not the guy who fiddles with one mike for the PA. :)
