I paid for a full years course in March of this year, & have made good steady progress . I tried formal one to one lessons & on a weekly basis with a professional teacher , but made very little progress for a large cash outlay. Simon Powis gives clear , concise lessons by video, which can be viewed as frequently as you like, while offering various exercises & challenges relating to them. Like one of your earlier contributors, I thought that the course lacked structure, & I jumped rather aimlessly between the different courses available: 1) Notation & sight reading 2) Technique & musicianship, 3)Theory & analysis & 4) Repertoire . The last course is a Certificate Course, which I ignored because i wasn't interested in gaining certification .. ... I SHOULD HAVE LOOKED AT IT , because it takes you through the entire course , with an ordered structure of 48 videos & lessons taken from the four main lessons, leading to an opportunity to submit a performance for appraisal. Since using this feature , learning has become much less of a struggle!!! i would not hesitate to recommend this course . If anyone wants a specific question answered re my course , I will endeavor to do so. Regards, Paul.
