Peterhouse partbooks

The Peterhouse partbooks are a collection of English partbooks dating from the sixteenth and seventeenth centuries. They are named “Peterhouse” after Peterhouse in Cambridge, where the books were kept for some time, and are now preserved in the Cambridge University Library. They are handwritten manuscripts, all written on paper. At some point in the mid-eighteenth century, the books were rebound, although the foliation and indices remained unchanged. Partbooks In partbook format, each of the voice parts has its own book; hence, here, there are separate books for the Triplex, Medius, Contratenor, Tenor, Bassus, and Organ parts. Partbooks were a practical way of circulating polyphony; each voice part could be copied much more quickly in separate volumes than in score format, individual books used less paper overall than one single volume in score format, they were cheaper to produce and easier for larger groups to sing from, and each singer only needed to carry one smaller volume. However, the disadvantage to the partbook format is that a small individual volume was easy to lose, and if any of the partbooks went missing, the others were potentially rendered useless. Such is the case
