Understanding music theory and composition is essential for musicians (whether performers or composers) of any genre and level. With this course, I hope to share my 10 years of experience in composition and music theory, as well as a great enjoyment for the field. I aim to exemplify the discussed theory through listening and (if applicable) playing examples, combining the established theories by discussing compositional parameters, making the playing of pieces and composing more accessible and organic. I aim for a personalized experience within the framework of demand.
