Interesting modulation from I - IV - IV/IV - i - V - I

[craigsapp]

Here is a repeated harmonic sequence of vi - IV - ii in a fugue:

First A minor section starting at m. 18:

Second A minor section starting at m. 81:

Here the original theme and its inversion are played at the same time (opening theme is up a 4th originally starting on G).

This piece would be useful to display in piano roll format ...

Different fugue by the same composer with the same harmonic sequence:

Did you create keyscapes for all scores? :)

[craigsapp]

Yes, all keyscapes are generated in advanced. There are 4 keyscapes for each score, so that will soon be 24,000 images (I had to regenerate them all twice this week due to the updates to every single score file related to instrumentation code enhancements to the scores.

Here is a good case of G major with a middle key region in E minor (relative minor of G major):

E minor starting at the repeat barline before m17:

Here is a piece in D minor, but there are a lot of unstable chords in it:

Here is a good example where the repetition structure of the music can be seen in the keyscape:

The form is ABABA, where each section is 32 measures long.
