Open Studio has a lot to offer. The different courses are taught by top-notch professionals, and there are plenty of good ideas to draw from. Peter is a very engaging teacher and a wonderful pianist, and the same can be said for Adam and others. That being said, I cancelled my membership during the trial period, because in order to really take advantage of the membership you need to have a lot of time to practice, and (for piano) you need to have several years of good piano training behind you. For instance, you will be able to progress much more rapidly if you already know all your major and minor scales, triads and inversions. If you know all your seventh chords, the blues scale, and have a basic knowledge of functional harmony so much the better. The point is that you need to be at least at the lower intermediate level to progress very well. If you're interested in developing this aspect of your music, Open Studio is a great and reasonably priced resource. I hope to rejoin when I have more practice time.
