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.

• Steel drums do this for me
• Oboes
• some brass instruments (depends on the player…if they can achieve that crystal clear tone)
• Taiko ensembles!
• if live, mandolin, dulcimer, lute

Edit 1: The venue acoustics will also factor heavily too.

Edit 2: ooh! Didgeridoos! Also best if live.

Hang / Hand pan and Hurdy Gurdy!

Feed me brussel sprouts and I can really feel the waves of sound.

They’re like little depth charges.

The French horn, from someone who knows how to play it well.

Gong
Singing bowls / tibetan bowls

All of them if you’re on enough LSD!
