From the Moretus Gradual, 1598 |
The chant notation (shown, left) looks very like that used in the editions most singers use today, though it used five staves and lacks some of the specialised note-shapes (singers will note that there don't seem to be any quilismas or liquescents). Again, it (obviously) doesn't include the editorial marks added by the monks of Solesmes to most modern editions.
Although the melodies are somewhat different from the ones used today, which have been restored by reference to the oldest available manuscripts, they are quite different from the simplified and clunkily-printed chant used immediately before the Solesmes-influenced 1907 Graduale Romanum, upon which later editions have been based, exemplified by the 1870 Pustet edition shown below.
