The Ensemble Claude Goudimel aims at an expressive style of singing and various arrangements of the group have been used to put into relief the melody of the psalm. With mixed voices it has been possible to cover the whole repertoire, which includes works written in higher and in medium tessitura. The more elaborate polyphonic settings keep only fragments of the psalm, with the use of three, four or five voices. In ornamented settings the voice that carries the melody is in the foreground, and sometimes the melody is sung by several voices. A more compact positioning has been adopted for the simpler settings. In some cases the psalm melody is entrusted to a single solo voice. The Ensemble aims to open again the pages of a Psalter that has survived the test of time.
