This Open Studio has everything for all levels for many instruments. My instrument happens to be the piano. I've learned so many things so far, jazz-related and otherwise. Adam is the best course instructor on piano as he is clear with his instructions and he shows much patience and enthusiasm both in his Guided Practice Sessions and in explaining the many concepts in his courses. I also enjoy his 'Shorts' on Facebook and Instagram, etc. I like Peter Martin as well, but since I'm new at playing jazz, I tend to get lost more in his courses as he moves very quickly. I do revisit his courses in hopes of learning a concept or two. So many other opportunities are provided with the Open Studio Community Page, as well as with their many 'live' sessions. Their website is easy to navigate especially with the new additions to it. Whenever I have a music question, it is answered quickly (thank you, Rachel!). This is the best jazz studio group to join if you are a musician and want to learn more, whatever level. Soo worth the $$$.
