I agree; it makes interesting reading. I wonder if we are seeing a dumbing down of instrumental prowess generally, with too easy access to on-line tuition hosted by players of meagre musicality themselves. Of course, there are some good players sharing their knowledge on the Internet, but there also seems be loads of self styled teachers demonstrating rather crude/inept versions of popular songs. I guess it all started earlier on when proper sheet music got overtaken by basic chord songbooks, but I daresay it’s a good thing that music making has now become far more accessible.
