These are private lessons in music composition. Prof. Carlson is a wonderful teacher and mentor. I was lucky enough to have him for the M20/120 series as well. This professor can help you with anything, including compositional roadblocks, theory issues, melody writing, ear training, and if you have an open ear, he'll give you all sorts of advice. Without having him Freshman and Sophomore year, my musical growth would have been severely stunted.
