Backrub chains are one of the best perks of choir (though getting to watch conductors during performances is pretty awesome too). The director--Dr. Z, Dr. L, or sometimes Graduate Assistant Extraordinaire Ian G. (to be hereafter called Ian, cause that's one heck of a title ::laughs::)--says, "Okay, massage this way," and the choir as a body turns to the left and rubs shoulders, and then the director says "Switch," and the choir turns to the right and rubs shoulders that way. You see, for singers, your instrument is your body--all the effort has to be mental, because if it creeps into your neck, shoulders, back, legs, it's going to affect the sound. It's wonderful, by the way--two of my favorite activities, singing and relaxing, rolled into one.
Yesterday, instead of having a backrub chain in the warm-up, we had one in the middle of the practice for Elijah, which means that Ian and Dr. L were lending their voices to the tenor line, since we have all of 5 avowed tenors. *ahem* All right, the point of all this lead-up is that Ian gives very good backrubs (he wears overshirts which make it very difficult to rub properly, incidentally, but on his other side was Dr. L, who undoubtedly did a much better job than I did)--I practically floated back to my seat because I was so relaxed, and I can drop my shoulders fully without agony now (apparently some aspect of college life has installed a permanent knot in my right shoulder which, until yesterday, meant that it was painful to drop my shoulders, and in fact I couldn't entirely). See, this is why he's Graduate Assistant Extraordinaire.
