Hello! This was my shot at creating a few variations on the theme that @Ivan1791 posted in the 'Challenges' section of the site yesterday. One thing to note was that the flatted sixth scale degree in measure 5 (Ab in the original key of C Major) was important to the original composer. I did my best to keep it around in most variations, although the harmony differs from the original intent in some cases. In minor key variations, I changed this to a sharped sixth scale degree in order to maintain the 'borrowed tone' aspect.
Let me know what you think overall! Thanks for listening.
EDIT: Brief explanations / explications of the genesis of each variation can be found in the musical score.
