This is me playing the cello. I used to do it professionally. Last week (Feb 2018) I took it off the case for no reason and started to play as well as for no reason I'd put it there thirteen years ago (when I got married) and let it there abandoned along all this years.
Prelude Suite Nº 1 - J. S. Bach
(Very bad quality video. I recorded it using my laptop web cam, the only option I had at hand.)
