Mine (Zimbabwean 🇿🇼) is the mbira.
For a feel of the sound: https://youtu.be/R5RMYh-n3LU
Jah Prayzah the guy singing is a renowned musician.
They seem to be using the mbira in modernized covers, but the metal pestle order seem the same as the more traditional looking ones.
P/S I’m not self promoting the YouTube link. It just shows how the mbira sounds unedited.
The Drumbone was invented in my country.
You asked for one, but I’ll try to sneak this in because it actually predates my country by 15 years: the Glass Armonica. Invented in 1761 by Benjamin Franklin himself.
Interesting!
