About this course: After a tremendous response from learners on Coursera, Berklee Online has created a Developing Your Musicianship specialization, and this course is the third course in the series. If you have a general understanding of music theory or if you have completed Developing Your Musicianship I and II, this course will continue to help you understand musical concepts, enabling you to create and perform contemporary music. Taught by Berklee College of Music professor George W. Russell, Jr., the course includes four lessons that delve into an intermediate level of harmony and ear training. The course will introduce you to new key signatures, and explore how they are constructed. You will continue to train your ear, learning to differentiate between the various intervals and chords that were explored in Developing Your Musicianship I and II. You will learn how to borrow chords from parallel tonalities (modal interchange), and how to write more common chord progressions. The course culminates with an assignment that asks you to compose and perform a composition using popular chord progressions. As with Developing Your Musicianship I and II, this course is designed to share the joy of creating music.
