A digital edition of the 389 Chorale Settings (Choralgesänge) by J.S. Bach

This repository has been made possible by Gertim Alberda,
who 'manually' digitalized all the 389 Bach 4-voice chorales,
as published by the Breitkopf edition 'nr. 3765'.
For this he meticulously transcribed all the notes and lyrics of that edition, by using the music notation editor MuseScore (MS).
He checked it against both BGA and NBA (Bach-Gesellschaft Ausgabe and Neue Bach-Ausgabe),
if there was any reasonable doubt for it, and even found and improved a couple of mistakes that way (<10).
Solely for performance reasons, he also applied many hidden (grey) extras in MS to make the scores and its phrasing
sound as realistic as possible; hidden fermatas, tempo changes, breath pauses, phrasing, note-cutbacks, etc.
This was all done to 'humanize' the playback and make it sound like a real choir performance (without words),
and given the technical limitations at that time (2016-2018).
Also see the Info tab on his website.

The full corpus resides on Gertim Alberda's dedicated website.
The scores there have synchronized play back (synthesized and human performances) available
and can be downloaded in various formats (mscz/xml/midi/mp3/pdf).
Here is an example of his playback page.
His intention is to have only human performances available (YT videos and/or mp3's) for all the scores,
but that is still an ongoing process
(see the changelog on his website).
He has agreed to share his MS files under a Creative Commons BY-NC-SA 4.0 license.
The license prohibits the use of the scores for any commercial purpose, including the training of machine learning models for use in commercial products.
