"Seven Symbols"

Select a symbol at random from the columns below and interpret it, either with your instrument, or with your voice, at any dynamic level, for any number of  repetitions, and for whatever duration you wish. When you have "performed" seven symbols, interpret the last symbol in the last column, as a sustained pitch of your choosing.  Once the entire ensemble has arrived at the final symbol, create a gradual decrescendo from the sustained pitch to silence.
