Ryan, I've seen these before, but don't know how to make them ... could the process be altered to include intonation? You make a perfect interval green, say, a major consonance blue, minor pink, dissonance yellow ... ?

MrCopper:

Another intersting idea is the fine training webpage of the St Mary's Singers out of Sydney.

http://stmaryssingers.com/all-titles.html

as well as their Youtube site : https://www.youtube.com/user/StMSSyd/featured

What about in sections where the bass rests, and perfect intervals exist between other voices? Do you then color whatever the "new bass" is as the lowest color?

Ben, you are channeling an inner Adam?

As to what colors: get harmonic: tonic is a color, dominant another, subdominant another, mediant another. When we modulate, the new tonic gets its color, modified by the original tonic: eg., the original blue tonic becomes new turquoise tonic, and the original red dominant becomes new green+red (?brown?) dominant.

And I ask again, how do you do this? Is is something so crude as midi-note-number to color?

The source in the example above is evidently from a MIDI sequence (since the playback smacks of MIDI synthesis), which (since notes and durations are just numbers), is easy enough for a computer graphics geek to process into what you see.

A year or so ago (when I first saw examples such as that above), I began to experiment with what I might be able to do within Finale - no fancy colors (yet now), just something that would play back nicely in the Scroll View. It has worked pretty well for visualizing (in another way than via usual Western notation).

Just to give an idea of what it looks like when printed, attache here is the Finale 2014 score of my 6-part Ave verum corpus in "Linear Flow" format, stripped of all text underlay and other markings (text in particular would mess up the steady flow of the music). I would upload the Finale .musx file if I could so that people with Finale 2014 could play back the result in Scroll View; however, since that isn't possible, I can email the .musx source file to anyone who is interested.

Here are the more conventional PDF score and MP3 sound file - the score for comparison with the Linear Flow version, and the sound file for listening to as you follow along in the Linear Flow score.

Note: I'll probably work on tweaking the results some in the near future. In fact, I've already uploaded a version with colored notes (instead of the black notes).

Chuck your pdf link does not seem to work: I end up at cpdl home page

Charles is correct regarding the source being a midi sequence. Youtube has several sites using this format. The creators use files from public domain midi files. I do not understand the value for training purposes, but viewers seem to enjoy watching the notes.
Mr Copper... I like your page display.

While many music software programs have the ability to scroll or print blocks of notes in color, I am at a loss for a practical application. Do they have a chant application ?. Are they the modern day scrolling "neumes" ?

There was a historic practice of scribing DO in green and FA in red, which we have expanded upon in A Gregorian Chant Coloring Book.

Manuscripts (machine images, engraving, etc.etc.) will only produce a 'grid of understanding' or a guide. The human touch (and intellect) will always be needed to add nuance, and the process will never succeed vice versa.
