Ponselle's recording career began with the acoustic horn, continued with electric recording, and ended on magnetic tape. Over her career, she made 166 commercial recordings (not including alternate takes), either in the studio or at Villa Pace. These are supplemented by live recordings from the 1930s, which include three complete operas and numerous songs and arias from her appearances on radio. Additionally, there are numerous "private" recordings made by Ponselle herself and others at the Villa Pace, from 1949 through the late 1970s.
