The composition is thought to have been intended to be part of a longer work, indicated by several blank pages following it in the autograph, which is held by the Fitzwilliam Museum in Cambridge.[2] The text of the extant music are the first verse of Psalm 102: "Hear my prayer, O Lord, and let my crying come unto thee." (Psalms 102:1). Purcell set it for an a cappella choir consisting of eight voice parts: two soprano parts, two altos, two tenors and two basses (SSAATTBB). The anthem is 34 measures long, and is written in the key of C minor. Some arrangements include a continuo instrumental accompaniment. Musicologist and historian Franklin B. Zimmerman designated the anthem as "Z. 15" in his catalogue of Purcell's works.[1] The duration of performances and recordings of this work varies considerably, from about two minutes to over three minutes in length.[3][4][2]
Purcell begins the composition with a simple setting of the first line on one tone, with only one exception, a minor third up on the word "O". After the first phrases, Purcell employs six to eight parts, in complex "pungent"[5] harmonies which build to what the conductor Robert King calls "an inexorable vocal crescendo lasting over three minutes, culminating on a monumental discord on the last repetition of 'come'".[2] Musicologist Timothy Dickey notes that Purcell "gradually amplified the vocal texture, and intensifies the harmonic complexity, until all eight voices combine in a towering dissonant tone cluster which desperately demands the final cadential resolution."[5]
The Swedish composer Sven-David Sandström used this piece for a composition of the same name, wherein, just shortly before the final cadence, the pieces collapses and builds up again from small bits of melody from the original.
