The Latin aeris is the genitive form for aer, "air" and for aes, "bronze," airain in French. In this piece, the natural resonances of a cymbal are highlighted through a feedback system. These metal resonances translate to audible air vibrations.

Aeris fits in the tradition of pieces exploring the sound of metal, like Mikrophonie I.

Frederick Skiff, Professor of Physics, explains how the cymbal sounds like a butterfly wandering through hyperspace. The picture was taken by Miranda Meyer on the day of Scientific Concert's première, October 27, 2019.
