Abstract This paper explains that the CD recording "The Lily and the Lamb: Chant and Polyphony from Medieval England" by Anonymous 4, an all female quartet that specializes in medieval music is an excellent example of this period's chant and polyphony music. The author points out that the recording is composed of eighteen tracks that are divided up into six different types of songs: one antiphon, five conductuses, two hymns, two motets, one processional hymn and seven sequences. The paper concludes that this recording is helpful in learning about sacred medieval music.
From the Paper "A sequence is a category of Medieval Latin chant and is also known as prose. It is part of the liturgy and comes after the Alleluia. It usually begins with an introductory phrase of the form "aa." Then phrases are paired together until the concluding phrase "n." The total form of a sequence usually written as: "aabbccddeeff...n." There are seven sequences in this recording and they range in length from a little over a minute to over eight minutes long. While listening to the sequences in this recording, I noticed that they all seemed to follow the same pattern with the voices."
