www.shapenote.net: Site creator Terre Schill says: "This website is a learning resource for both experienced and new shapenote singers. Here you can find free audio .mus files of hymn tunes in 19th century shapenote songbooks which are still in use in singings across the United States today. It is my hope that these may make it easier for people to learn unfamiliar parts (like tenor to a complicated song they want to lead), familiarize more of us with some of the seldom-sung tunes, and most especially to help new singers learn the tunes so they can fully enjoy singing."
