"Dream Song" is an American air in 4/4 time and G Major. The parts are played AAB. Samuel Bayard relates "(This tune) was heard in a dream...Mrs. Armstrong relates that she dreamed of seeing her Uncle Laney--the most accomplished fiddler in the family and the one who knew the greatest store of old music--sitting on a log in a clearing and playing this air on his violin. The tune impressed her so by its wistful quality that she still recalled it when awake; so she at once tried it out on her fiddle and committed it to memory. The tune itself is very much in the style of a British folk melody". Bayard groups it with "Waltzing With the One I Love". and "Laney Tunin' His Fiddle". All three tunes were composed by Sarah Armstrong. Bayard says that these tunes "demonstrate that the making of melodies is not yet quite dead in Pennsylvania". It was collected from Mrs. Sarah Armstrong, (near) Derry, Pennsylvania on November 18, 1943 by Samuel Bayard.
