This is one of hundreds of short subjects produced by Vitaphone and competing companies in the early days of sound. Often vaudeville or cabaret acts, they ranged all over the shop.
In this one, Barbara Kerjulf's act consists of a singer, three harpists and a violinist, all seeming to be very young women -- the harpist on the left looks to be about 16. They sing sentimental, old-fashioned songs, but their dress is very modern (for 1929), including bobbed hair and knee-length skirts.
Visually, it's actually quite advanced for the era. There are frequent cuts, from the initial view of all the performers, to medium close-ups of the individuals. Sometimes the camera pans.
