ABSTRACT
The earliest recordings of an educational character were language instruction records dating from 1891. Columbia’s “Phono Vocal Method” (1910) offered lessons by means of recorded examples keyed to textbooks. Later Columbia efforts in the educational arena included children’s songs, the Columbia History of Music, dramatic audio reenactments of landmark events, poetry readings, and add-a-part discs for use by musicians. In 1928 Columbia issued lectures on physics and astronomy. During World War II it made Morse Code training discs.
