"Music/Musician/Musicianer"

The great Louis 'Scan' Tester of Horsted Keynes played Anglo-concertina, bandoneon, keyed bugle, fiddle and piano to my knowledge; he may have played others. He always referred to whatever instrument he as playing as a 'music' and several of the older pre-revival rural musicians that we met when we first came to Sussex in the 1960s did the same.
In a recorded interview that I did with him he in talking about his concertina made by Crabb and says:-
It's a very fine music.
.... and elsewhere in the interview he says:-
I always takes great care of my musics.
