My name is Marc Sabatella, founder and director of the Mastering MuseScore School. I am one of the developers and chief ambassadors for MuseScore, and I have been teaching music online for over 25 years. Here at the Mastering MuseScore School, I focus on helping you create the best music you can.

MuseScore is the world's most popular music notation program, and it is revolutionizing the way people create music. It does virtually everything the expensive commercial notation packages do, and it does it all for free. And speaking of free, I have long offered some of the most amazing free resources for music education, starting with my groundbreaking Jazz Improvisation Primer.

Our flagship products are Mastering MuseScore: Complete Online Course and our two new newest courses, Basic Music Theory and Harmony and Chord Progressions. These video-based courses provide the clearest and most thorough training on these subjects available anywhere. We also have some exciting new resources in the works for learning about music creation - theory, composition, improvisation, etc. In addition, we offer a site subscription via the All-Access Membership so you can enjoy all the content on the entire site, including new courses as they become available.
