Tu Es Petrus, in the style of a march, is a bold musical proclamation. In this setting
Demessieux superimposes two different chant themes, both from the Feast
of Saints Peter and Paul. The five-note pedal theme, presented in a
descending sequence throughout the piece, is taken from the fifth
antiphon at first vespers. Above this, the uppermost voice quotes the
versicle of the Alleluia from the mass. For those familiar with these
chants, Demessieux is musically referencing a double statement of the
text Tu Es Petrus, simultaneously in the highest and lowest registers of
the organ.

The melody is in the top voice. The chords are both in the left and right hand, the latter playing the melody at the same time.

Are those chords in the hands, and the melody on the pedals?
