For example, the first “tonus” they sang was:—
- Coro I.

In the last verse of each psalm they sing the closing words more slowly, and with greater emphasis, and, instead of the inflexion, end with a sustained chord of three notes sung piano, for example, in the first:
![\relative c { << \new Voice = "a" { \override Score.TimeSignature #'stencil = ##f \time 13/4 \clef bass \autoBeamOff g'4 g16 g g g g g g g8 g g4 g g g2\fermata <g, b' d>1^\p\fermata \bar ".." } \new Lyrics \lyricmode { \set associatedVoice = #"a" Qui4 di16 -- li -- gunt no -- men e -- jus ha8 -- bi -- ta4 -- bunt in e2 -- a.1 } >> }](http://upload.wikimedia.org/score/9/e/9eyqamvioohs2ju4z42b6gewu00jc4r/9eyqamvi.png)
At the commencement of each psalm comes an antiphon, or several, by way of prelude; usually these in “canto fermo” are sung by two altos very coarsely and harshly, so, too, is the first half verse of the psalm itself, and at the second the system of responses by the male choirs comes into play. I am
