This is a collection of transcriptions of sequences done by Richard Crocker's students throughout the years. The sequences are taken from two sources: Corpus Troporium(ML3080.C791) and Analecta Hymnica Medii Aevi, vols. 53-55 (BV468.A6). There are about 1400 manuscripts in the collection.

Richard (Lincoln) Crocker (b. Roxbury, Massachusettes, 17 February 1927). Musicologist. He graduated from Yale College (BA 1950) and completed the doctorate under Leo Schrade in 1957 with a dissertation on the Limoges prosae. After teaching at Yale (1955-63), he was assistant professor (1963-7), associate professor (1967-71), and full professor (1971-94) at the University of California, Berkeley. He became known for his independent ideas in A History of Musical Style (1966) and in his article, The Troping Hypothesis(Musical Quarterly, 1966), for which he was awarded the Einstein Prize by the American Musicological Society. In 1969 he received a Guggenheim Fellowship. His work at Berkeley in developing methods for teaching non-musicians is embodied in Listening to Music (with Ann Basart, 1971). Crocker's major scholarly contribution, however, is to the history and analysis of the medieval sequence, culminating in The Early Medieval Sequence (1977). His work on music theory and early polyphony has been important in providing the basis for a new understanding of principles of composition in the Middle Ages, particularly those connected with tonal order.
