Perhaps “Brass Noise”

The musician who goes by the name id m theft able, and who is based in Portland, Maine, does these incredible videos where he places a tuba, amplified by a mic, in the environment and just records the resulting resonance. He does this with other instruments, as well, like the sound of light snow on a drum and freezing rain on a guitar. There’s a lengthy playlist of his tuba videos, which generally have prosaic titles, such as “A tuba by the falls (with a microphone in it) at dusk, April 19th 2020” and “A tuba at Whitney’s Falls (with a microphone in it), September 1st 2024.” The most recent id m theft able tuba video, “A tuba at one of the falls revealed when Dundee Pond was drained (with a microphone in it)” (note the absence of a date), was uploaded on September 3, 2024, and features a metallic drone that has the threatening vibrancy of a distant buzzsaw. It’s nearly 25 minutes of the deeply raspy rumble. The sound is sufficiently routinized and static to qualify as a colored noise, perhaps “brass noise,” rather than merely white or brown.
