These songs are designed for teaching sight-reading.  The Song Reader videos and printouts come from the 1914 edition of McLauglin and Gilchrist's "Song Reader", published by Ginn and Company, and now in the public domain. I stumbled across this treasure in a thrift store and it is now one of my favorite music resources. Even so, the text was small and black and white and I believe the videos and printouts I recreated make the materials much easier to digest for children.  (Incomplete.)
