Lucy Isabelle Marsh (April 10, 1878 – January 20, 1956) was an American lyric soprano who made her career as a professional recording artist for the Victor Talking Machine Company. She was an anonymous mainstay of the regular recording program of the company from 1909 into the late 1920s. At the same time, she quickly won popular and critical recognition under her own name as a major artist on recordings for Victor.
Marsh obtained training in Paris under Baldelli, and under Trabadelo, who also taught Mary Garden. She studied under John Walter Hall in New York.
Marsh sang in church choirs, and became lead soprano in important churches in New York City. As a Flower Maiden in the opera "Parsifal" she is known to have given nine performances at the Metropolitan Opera between November 1904 and March 1905. In 1908 she recorded three sides for Columbia Records.
In 1909 Marsh was engaged by The Victor Talking Machine Company, beginning a dual career as a "recording artist" and as a technically and artistically accomplished singer. Although she occasionally appeared on stage, she was known mostly through her many recordings.
The "recording artist" was essential to the commercial success of recording companies such as Victor in the days of acoustic recording technology, roughly from 1903 through 1924. Singers were required whose sound quality registered well through a mechanical diaphragm, who were reliable workers, and who were quick studies at learning the latest song or an arrangement prepared for a recording. Such singers had to master the techniques of singing into a horn, which included knowing the best distance from the horn to stand for their voice, how to back off to avoid blasting and move forward for soft passages, how to adopt a position to blend with a partner or change positions to maintain the best balance when alternating lead passages with a partner or accompanist. Marsh herself left a description of the situation.
