Music theory

Draft

Introduction

This page will shortly introduce some basic elements of music theory, in particular with the idea in mind to help people getting started in improvisation and accompaniment. We are particularly interested in educational aspects of music software and computer-enhanced or computer-driven instruments. As much as possible we shall point to external resources. EduTechWiki can't become a music wiki ;) - Daniel K. Schneider, 9 September 2011
