This app provides music lessons with audio topic by topic. Jazz Harmony is basic and advanced “knowledge and know-how” for most contemporary music like Jazz, Rock, Pop, even Film Score with full orchestra and many more. You can utilize each study content immediately on your music activities. Because everything (especially the order of contents to study) on this app is carefully designed to be easily understandable for each current stage in learning. To achieve that, we designed all contents based on processes of musical thinking for actual music productions and performances.

All contents are written and organized by a professional composer working globally over 20 years for films and video-games. Also some patents of music information processing (example : US8492636 B2) were invented by him.
