The selected 77 tunes lend themselves best to the Autoharp, a unique, distinctly American instrument. They are also well suited for ensembles using other folk instruments in conjunction with the Autoharp, such as guitar, banjo, mandolin, ukulele and dobro. The songs are chorded to accommodate all Autoharp playing styles from simple accompaniment strumming to melody picking. The majority of arrangements are for the 15 chord model, the most commonly used Autoharp. However, in some cases the harmony of the piece requires chords found only on the 21 chord model. This is noted under the title of the song.
