I'm a fan of the album Hear The Colors, who is interested in where and how those colors actually appear in individual songs.
I'm a musician / songwriter who likes to try and explore new perspectives on how to approach harmony.
I'm a curious person, I love music, and while I'm not sure of my ability to make it, I like to experiment with a variety of tools that help.
In that case, you might be interested in this application.
In principle, it's a tool that conveys the approach to harmony I've created. It can be viewed in two main ways:
The first is mathematical: harmonic frequencies and shifts of 1 to 6 halftones
The second is artistic / intuitive: color transitions between chords
One of my main goals was to bring more intuitiveness to music theory, so I subjectively assigned six colors to these shifts, according to the emotion the transitions between the chords evoked in me (descriptions of these associations are in the application itself, after clicking on the question mark at the top right).
The intention is not to replace traditional music theory, but to approach it from a different angle, in my opinion, an interesting angle, which brings certain advantages as well as certain limits. For this reason, I personally find it most interesting to combine both approaches.
The main difference between my system and traditional music theory is that the anchors on which the composer relies on are not the scales and keys, but mostly the color relationships between chords. The initial inspiration for the album Hear The Colors was to verify this system in practice. Specifically, I decided to compose a song for each of the two color combinations. I did not limit myself to the two colors strictly to allow the song to deviate slightly, if you explicitly asked, but most of each song is always in the two colors.
You can visually see what it looks like in practice by opening and playing individual songs in the application. I finished the application and created the songs in it only after the whole album was finished, so it was also a very interesting process for me, which enabled the creation of these alternative piano versions of the songs, and I am very happy to see their harmony.
These songs can also serve as a practical inspiration for how to use the system. In order for the application to be useful for composers, it is possible to export the recorded sequence of chords to a MIDI file and use this file as a starting point in your own song in any DAW such as Logic, Pro Tools, Ableton, Cubase, etc...
