This is the key. People singing together happens rarely in the places I have lived. I don't hear anyone whistling a tune more than once a year if that. But almost everyone on public transport is wearing earbuds and in their own little world. Sometimes they have their music so loud that you can listen comfortable if sitting near them.
In Germany a further nail in the coffin: recently Kindergartens have been chased by the local performing rights company for licenses if the kids sing. I don't know the outcome but even the thought of it is repellant. Do I have to apply for a license if I want to sing in the shower?
Oh great! That is the key how to save ethnic music!
It has no copyright by definition! It is folk music therefore no license required! Therefore those kindergartens have to start use FOLK MUSIC ONLY!
In general - if music is recorded then it is saved.
Performance is secondary thing... and if there is a demand for it - it would be always possible to relearn for performance.
Recording would be complete if not only music would be recorded but techniques of playing and construction of instruments too.
But certainly music exist in the totality of the culture and to recreate it completely one have to live in it, and this would be impossible and cultures will disappear very fast.
Therefore it has to be recorded now if it is still exist.
I'd better speak by music...Please listen my guitar at Spotify, Apple Music, Amazon, etc.
