e-gong sound sample

Here’s an example of the 22-inch electric gong I keep at home. Its a short cyclical composition highlighting the harmonic relationship between some of the stronger resonances in the gong. At any time, there are no more than two sinewave frequencies exciting it; we see that the energy does not remain concentrated at these frequencies but spreads out to activate other resonant modes.  This effect makes the sound evolve into washes of color.
