Violinist Mischa Elman performs a set of two of the most recognizable popular classic violin pieces: "Humoresque" composed by Antonín Dvorák, and "Gavotte" by François-Joseph Gossec. He is accompanied off screen by pianist Josef Bonime, although Bonime's instrument can be seen in the background behind Elman on screen. In one continuous single shot, the stationary camera focuses in squarely on Elman as he performs the two pieces.

This short was released in connection with the 20th anniversary of Warner Brothers' first exhibition of the Vitaphone sound-on-film process on 6 August 1926. The film highlights Thomas A. Edison and Alexander Graham Bell's efforts that contributed to sound movies and acknowledges the work of Lee De Forest. Brief excerpts from the August 1926 exhibition follow. Clips are then shown from a number of Warner Brothers features, four from the 1920s, the remainder from 1946/47.
