I have created a new set of unique scales that focus on harmonic modulations. I arranged the basic scales in a consecutive orders so all the possible chords in a group are repesented one by one with different inverted configurations on every key.
The scales can never be a nice sounded piece harmonically without further development. With more details and varieties added in, the piece then becomes an Etude.
There are sheet music pdfs and mp3 audio on my topic page. Each measure represents a complete chord with a specific inverted configuration that scattered on the single running notes.
Here's an experiment you can do. After printed the pdf, use scissors to cut each measure into a puzzle piece. Try to rematch the segments in the compatible ways, so the musical phrases will sound connected and flow smoothly. Like the real puzzles, only certain pieces can be fit in together correctly.
I'm still working on the library of my scales. I got 432 unique chord segments so far. I plan to get over 2,000.
