I’m thinking things like harp and marimba
You can really feel the waves of sound
The cello. Fuckin’ love it.
I came in here all wrong. I was going to say a large office printer/copy machine has that thrum you feel, the rhythm of each page flipping and printing, and the smell of warm micro plastics.
The humble kalimba has some of the qualities I think you are describing. Also just a regular nylon string guitar.
Yes, especially when you retune the pitch waaaay down and also slow it down like a fraction of the original speed
Hang / Hand pan and Hurdy Gurdy!
Upright piano with the front panel taken off
Feed me brussel sprouts and I can really feel the waves of sound.
They’re like little depth charges.
All of them if you’re on enough LSD!
bass guitar for sure
