YouTube Highlight: AuthenticSound

Authentic Sound is a delightful channel run by Belgian musician Wim Winters. Besides his marvelous playing he discusses musicology, history, instruments, and performance practice. 

He raises matters that performers often don't want to dwell on because they require a lot of work to sort out before you can settle on a reasonable reading of the score, and that non-performers (like me) just won't think of.

Here he is on a passage of Beethoven:

There's so much fun and insight here to dig into, you can disappear if you have the time.
