A History of Early Microphone Singing, 1925–1939: American Mainstream Popular Singing at the Advent of Electronic Microphone Amplification

In the late 1920s and throughout the 1930s, a new style of singing and vocal technique emerged in American popular music. This has been called “microphone singing.” The popular usage of the expression “microphone singer” in American culture usually refers to a vocalist who characteristically works with the aid of electronic amplification via a microphone, and whose music-performance approach assumes the use of this technology. At its advent, the instrument known as the “microphone” (common shorthand for an electronically amplified sound-signal pickup), as it was used in recording, radio, and public address, made changes in vocal technique and musical style possible, even necessary. There were specific social and economic contexts in which these changes took place, and which had bearing on these changes. Therefore, when considering the earliest microphone singing, it is beneficial to examine the historical context in which it developed.
