Hello I really like your videos about jazz piano, they are super educational! Now I spontaneously responded to an advertisement from you and bought a product. Meant I bought a pdf with warm-up exercises, for 17 dollars instead of 77. But I only got access to the platform where everything is encrypted. So what did I really buy? Can someone explain this to me? Thank you and kind regards, Stefan Joss (steff.joss@gmx.ch) _______ Update: I first had a problem with the handling of the online platform. However, Openstudio immediately responded to my comment and the problem was resolved. I think Openstudio's inputs are great and very practical. For me as a musician without complete training, the videos of Peter and Adam are a great enrichment. Thank you very much for this, keep up the good work.
