It is a difficult journey trying to get an ebook out there. Especially with video and audio to contend with. So I'm two thirds of my way through writing The Art of Class. Part 1: Overture is a free download here. https://designrr.s3.amazonaws.com/karen_at_musicdesignuk.com_22828/a46f842a283e8d81fafa021f0b0ddb7a5968af7ed557936daf1d715b9023d198
Part 2 Improvisation will be coming out on ibooks soon! Then the big guns, part 3. All about playing for Free Class. A mammoth task but will be next in line.
