On a somewhat different matter though, I also make concentration faces when I play, and they look quite strange.

Hi, I was listening to some recordings and noticed that many of them contain (when turned to a higher volume) the sounds of the Pianist whilst playing. This can take the form of a humming noise or other similar small verbal expression. This has never even crossed my mind when playing, apart form when messing around in practice and deliberatley counting / bumping the beat. Is it a common thing, how many here do this? Thanks in advance.
