Massive thanks to Sebarus and Avelon21 for critiquing my writing and helping with the process!
The music used in this story is CC and arranged by myself in GarageBand, using various built-in tools and a 3rd-party plugin called "Magical 8bit Plug 2" which is open source and released under GPLv3.
References to the manuscript and an arrangement for piano by Czerny were made while arranging the music, both are in Public Domain, and can be found here.
The following two recordings have been inspirations to me while making the music:
A recording by Kimiko Ishizaka on piano, with visualization by Smalin
A recording by Glenn Gould on organ
Hope you enjoy!
