The "Mastering Rhythm" course was so great that I think it deserves a sequel and a three-quel :) There really isn't that much material explicitly on rhythm out there for us "non-drummers." The gems are few and far between. I count "Mastering Rhythm" as one of those pedagogical gems on rhythm. You've got the likes of 13 pro's, including Melissa Aldana and Alexa Tarantino, all giving specific lessons on the art of rhythm and time feel. Once elusive concepts now feel tangible. Looks like you CAN teach rhythm in an intention way! Rhythm is one of the key elements that separates the "amateur sound" from the professional, so buy this course NOW :)
