Publisher Desc.  "Canons Firing From an Ever Rising Staircase," Or, Heed the Effer's Frantic Calls. This is a piece for clarinet choir written by John Gibson of JB Linear Music. It is set for solo Eb clarinet; Bb clarinets 1,2, and 3; 2 Alto clarinets (with alternate Bb parts); 2 Bass clarinets; Bb Contrabass clarinet (with an alternate Eb Contra Alto part). To explain the title just a bit, the ever rising staircase is an aural trick that, if done precisely, sounds like the music keeps rising without really doing so. This was derived from what is called a Shepard's Tone. The canons firing are not cannons! The bass instruments play small sections of actual canons (like fancy rounds) written by J S Bach, Mozart, and others. Each time the solo Eb clarinet (the Effer) announces the coming canon firing in a frantic sort of way. Considering the Eb clarinet part, and the need for the Bb clarinets to carry the rising staircase, this is for an advanced group. It runs a little over 3 minutes in length. The recording is computer generated, although I plan to record a live version someday.
