How important is foot tapping when playing?
I never used to bother but playing in session one person does it really loud and they told me that it is very important to their playing.
I ignored it at first but I was practicing with metronome again recently and then I started tapping with the metronome and suddenly I found it much more immersive somehow.
I used to think it was just a nearly useless aesthetic preference but perhaps there is more to it?
I actually realised there are other ways I would move to the beat in the past but never thought of it as time keeping but when I experimented a little more since the tap revelation I realised it had the same effect. When I played fiddle sometimes when I really got into it I would start rocking side to side in time. I tried this again the other day with the intention of keeping the beat and it seems to have the same effect of foot tapping, so a valid alternative, acting as a mechanical metronome would rocking on the beats.
