One of my studio moms posted a link to this video on Facebook:
I thought it was really cool and started checking more into this amazing pianist/improviser, Richard Grayson. After digging a while, I unearthed a link to his Improvising at the Keyboard handbook, a work in progress that is already an incredibly helpful resource for anyone interested in learning to improvise. His explanations and examples are easy to understand and put into practice. I’m looking forward to using it myself and with my students!
