When I have to make “Kaddish” recordings in the all-too-live exit foyer backstage, I have to play as soft as I possibly can to avoid getting distortion on the iTalk recording, which doesn’t have input level controls. Since we’re playing a musical that uses mutes a lot, though, I finally realized the mute could help. Tonight’s Kaddish is played entirely on muted horn. It worked! Muting brought the amplitude of my usual playing down to something iTalk could handle, and I didn’t have to hold back so much.
