A new picture of music at the basilica of St. Peter's in the fifteenth century emerges in Christopher A. Reynolds's fascinating chronicle of this rich period of Italian musical history. Reynolds examines archival documents, musical styles, and issues of artistic patronage and cultural context in a fertile consideration of the ways historical and musical currents affected each other. This work is both a historical account of performers and composers and an examination of how their music revealed their cultural values and educational backgrounds. Reynolds analyzes several anonymous masses copied at St. Peter's, proposing attributions that have biographical implications for the composers. Taken together, the archival records and the music sung at St. Peter's reveal a much clearer picture of musical life at the basilica than either source would alone. The contents of the St. Peter's choirbook help document musical life as surely as that musical life—insofar as it can be reconstructed from the archives—illumines the choirbook.
