I've tried several online piano courses before discovering OpenStudioJazz, but none of them met my needs quite like this one. Since joining, I've been improving faster than I imagined. Not only have I been playing more, but I've also been enjoying the process a lot! The key part that makes OpenStudioJazz great for me is the 'Guided Practice Sessions' (GPS). They are engaging, fun, and easy to follow along with, making practice something I look forward to rather than a chore. The pacing of the courses is excelent as well, striking the perfect balance between challenging and manageable. The courses emphasize picking things up by ear, which really helps with improving my musicality. Overall, I couldn't be happier with OpenStudioJazz. Highly recommended to anyone serious about mastering jazz piano!
