This sheet music is written in E mode, which is for distress. It evokes softness. Jesus Christ is described in the first part (be careful to the way you pronounce the “O”) and then there are the imitation sentences with “misericordia.” The last section has a convention stereotype; the descending hexachord represents suffering on “Miserere mei” and the ascending “Deus meus” represents hope. This sheet music is balanced and with no particular difficulty. The composer was attentive to the understanding of the whole text.
