They Produce Unusual and Loud Sounds

My art is not political, because as a composer I am involved in the most abstract kind of art – music. It is a sound world without semantic meanings, and this is what I very much like about it. But sometimes I have used my instruments in demonstrations, because people there usually play whistles or percussion to attract attention. My pipes work very well for these purposes, because they produce unusual and loud sounds. Thus they certainly attract notice.
