Portland singer Anna Stoerch has shared her pet project with the world: compiling complete details for every tune in the 1991 revision of The Sacred Harp tunebook.
Entering author, composer, time signature, and so on for every tune would take one person a long time, but with everyone's help, it'll be done before you can say "Lord Revive Us".
When the data's ready, we'll create a form that will let you search the collection to find all the minor songs...in 2/4...that were written between 1950 and 2000...that contain major chords...it'll be a Great Day indeed!
So take a couple minutes, open your book, and do some data entry for the benefit of singers everywhere - then enter your comments on sheet 2, add yourself as a contributor on sheet 3, and tell all your friends!
