From the poll, it looks like over 2/3 of us so far come from places where there's a fair amount of talking going on while on the mat. My first dojo the only person who talked on the mat was the sensei. My current one is quite the chatty place. One difference I've noticed, is in my first place I missed the chance to occasionally ask if my attack was OK for my partner when I was uke, but otherwise there wasn't much to say, anyway.
In my current dojo, nearly everyone, from those with 2 weeks under their new white belt to the yudansha, feels the need to 'elaborate on the instruction we received'.
Wouldn't be too bad, all the talking, if only 20% of the 'correction' was correct
Unfortunately, all that extra instruction is usually wrong.
I was recently at a seminar where many of the students were of styles different than the sensei teaching; some of them, in mid-'correction' to me, would be stopped by the instructor and told they were incorrect. Once he moved on, back they went to telling me 'how it was done'. I wonder how much of all this talking going on is about the weather, and how much is the curious phenomena of students feeling that the instructor was unable to get the point across, but that they
will now do so?
