Nota de aplicación
Bowed psalteries, intended to be played flat, and manufactured from the 1920s through the 1960s as a combination of the traits of violins and ukuleles. Ukelins had two sets of strings: one set of sixteen melody strings tuned to C, and four sets of four strings each, tuned to four-note chords. The chord strings were plucked with one hand, and the melody strings were played with a bow by the other. They were initially produced by the Phonoharp Company of East Boston, Massachusetts, and sold by door-to-door salesmen.
