What a crazy question.

There is this 33 volume thick series where last 20 volumes are spent on tea parties. In the series there is an instrument modeled after bandura called harspiel that is often played on those tea parties.

I have made a 2h+ bandura music compliation just to immerese myself more into the world of those tea parties.

The series is called Ascendance of a Bookworm and there is whole instance dedicated to it.

Flight of the Conchords. “There ain’t no party like Nana’s tea parties!”

When I have company I tend to play the Planet Coaster and Planet Zoo soundtracks or maybe Of Monsters And Men

Nujabe

I’m a big fan of Enya.

Some of the lower-tempo tracks from Stardew Valley, like ‘Cloud Country’ or ‘Wild Horseradish Jam’.

Mark Sherman plays some great vibes charts. Interplay is great background music for a gathering.

Muzak.

Have you tried death metal? 😅

You could try the classic Cat Stevens album Tea for the Tillerman

I don’t know what kind of tea parties you “throw”, so to say. But here is a suggestion: https://www.youtube.com/watch?v=eELH0ivexKA

If not this, some Erik Satie maybe?

Hiromi Uehara
