The next new resource for the new Tune Book is the “Tune Book Harmony”. This lists all of the tunes published in the 2015, 1987 and 1953 editions of the Tune Book, including supplements, showing the tune numbers in each edition. This data was the basis for the Comparison Charts for the Tune Book that were published a few days ago.
A companion Song Book Harmony is in preparation. Online versions of both are in development. Printable (MS Word and PDF) versions will be published first.
