My mixing bowls are glass, and ring nicely when struck with a metal spoon. The standard ratio between bowl sizes used for cooking would seem to define familiar intervals of octaves, fifths etc. (Un)fortunately, the tolerances used in manufacturing my bowl set don’t seem to have taken western tonality into account.
A refrigerator door structures the composition in the following way. The pressure balance in our basement freezer is a little off, so once you close the door, it is extremely difficult to open again for ~5 minutes. Here, that means that notes and phrases are repeated only sparsely. The bowls define three notes, and with a rest I maximize the distance between repeats by rotating the sequence of four like so: 123R.23R1.3R12.R123. Then the whole phrase is repeated along-side a pitched up/down copy.
I loved the process, but the final product was, for me, not much fun to listen to. So, I identified a pleasing segment spanning about 6 seconds and paulstretched it 20x for an eerie drone-ified ode to my kitchen.
