Timing

Performing Forces, Melody, and Texture

Text and Form:

Small ensemble of men singing in four-part polyphony; a mostly conjunct melody with a lot of melismas in triple meter at a slow tempo. The section ends with a cadence on open, hollow-sounding harmonies such as octaves and fifths.

A: Agnus Dei, qui tollis peccata mundi, Miserere nobis

This section begins with faster notes sung by the alto voice. Note that it ends with a cadence to hollowing-sounding intervals of the fifth and octave, just like the first section had.

B: Agnus Dei, qui tollis peccata mundi, Miserere nobis

Same music as at the beginning.

A: Agnus Dei, qui tollis peccata mundi, Miserere nobis
