I watched several of Adam Maness's YouTube videos at the recommendation of my piano teacher. I found them very interesting and easy to follow. Adam doesn't rush through explanations of technical terms as some of the other music instructional videos that I've reviewed do. I have been playing piano off and on for many years and can sight-read music well. However, my piano teacher has been encouraging me to learn music theory and work on improvisation skills. Open Studio Jazz has been the perfect fit for me in this regard. My piano teacher also signed up and we are working through the Jump Start Jazz Piano course together.
