Open Studio has some of the best teachers I have seen in the industry. I have been playing the piano for a few years, but, did not have a full grasp of the theories behind what I was doing. I watched my first YouTube preview of a course from Open Studio and I was sold. I am two weeks into my first course now. It is amazing how much I have learned for the past two weeks. Proper chord voicing, scales, tensions, rootless voicing, and the list goes on. Above all, these guys even practice WITH YOU! They hold your hand through proper way to practice, which improves how fast I am able to have the concepts locked under my fingertips. All in all, if you invest in a journey with Open Studio and take your time through the lessons, you will thank me later :-). - Eddie
