By the late nineteenth century, concert publishers increasingly printed cadenzas—solo passages that performers had previously been expected to improvise. Some historians cite this shift as evidence that improvisation quickly vanished, but musicologist Amara Voss argues that publication counts alone cannot establish that inference. Comparing annotated musical parts with early recordings, Voss found that performers often preserved a printed cadenza’s opening and closing gestures while replacing its middle. Even these departures, however, usually followed the edition’s overall length and harmonic route. Annotations listing alternative transitions indicate that some variation was planned in advance rather than invented during a concert. Lesser-known players changed printed material less extensively than virtuosos did, but neither group followed the editions uniformly.
