I had completely forgotten I had done that. It's not too bad I guess, but listening now, I think I am inclined to go too far too quickly, even in that short section. I have done similar things privately for a considerable number of people on forums and in person over the last ten years with varying degrees of success, "success" being defined as making the recipient a confident, creative pianist in his or her own right, and not an imitation Ted, which outcome I would view as a failure.
Also, improvisation is such a peculiarly personal endeavour that there are severe limits on the validity of any approach which purports to understand the minds and processes of all creators. In the nature of art such a thing cannot exist because creating spontaneous music is not like bolting together a Meccano model from an instruction booklet, although some academics seem to think it should be, and worse still, teach it as if that were the case.
I am quite happy to participate in a thread about how to improvise. These days we have the help of recordings and videos which can be made easily and transmitted in minutes. However, there might be very real drawbacks in any creative tuition which has input from too few minds and is received by too few minds. Also, some of the most interesting improvisers here, who could undoubtedly contribute much knowledge, are very busy musicians with busy lives, in varying degrees professional, and not retired amateurs like me.
Let us first see how broad the field of interest in such a thread is.
