In this series we take a look at how modal chord progressions are constructed, and learn a quick and effective system that will enable you to make up your own chord progressions, or even compose songs, using modal harmony.

  • Learn fresh and unusual sounds.
  • Understand how modal harmony works.
  • Learn by making music, without too much theory.
  • Lifetime Access (including future updates) on all your devices.

I am a music geek fascinated with learning new things, and improving my guitar skills. But I'm also very passionate about helping others do the same!

After studying in the Greek National Conservatory, and Berklee College of Music, I began performing and teaching privately in 2001.

Since then, I have been developing new methods for effective musical training. My mission with String Systems is to share them with the world :-)
