“The Mystery Unveiled “

This course is developed to alleviate the mystery around theory. Theory is a great tool to speed up the process of learning tunes, connecting to chord changes as an improvisor and to develop material as an aspiring composer. This theory course is developed as an easy to follow step by step process with time to present the questions you always wanted to ask. It will be a lot of fun using creative methods, audio samples, hands on excercises and handouts with as a foundation a publication written by Marc Mommaas: ‘Improvisation; A theoretical and creative reference guide’ ©2019. Style and level is not of importance, and by the end of the semester you will be able to analyze a standard like a pro and learn chord changes as harmonic sentences.

This course is for all musicians, from vocalists, to pianists and drummers, all are welcome.

This course is developed and guided by in demand educator, composer and saxophonist MARC MOMMAAS (professor at the New School, co-founder of NYJW and HJW). Ever felt that you are falling short in understanding the main principles of harmony and theory? Then this is the class for you. This course will cover:

  • chord/scale relationships
  • the modes
  • voiceleading principles
  • voicings
  • upper extensions
  • major and minor tonality
  • analysis of tunes

Level: Beginner / intermediate.
