Marking all the ictuses helps the conductor and singers see the groups
of twos and threes that form the basis of chant rhythm. This is further
reinforced by counting out the resulting patterns, beginning with one on
the ictus, followed by two and, as necessary, three on the non-ictic
notes. Just as solfeggio reinforces the relative pitches of a melody,
counting instills a clear sense of its underlying rhythm.
Of itself, the ictus is purely organizational, and indicates
no qualitative change in the rendering of the note—not emphasis, not
lengthening. The basic rhythmic groups of twos and threes are further
combined to form larger groups that either tend to rise (arsis) or fall
(thesis).
But it's still taught at the Chant Intensives.
- Le nombre musical gregorian, pp. 433-434The ictus indicating the grouping of notes should be rendered as in any music of legato character, namely with infinite gradations of nuances.
a) Sometimes our ear is made aware of the subdivisions of the rhythm
by a shade of intensity given to the icdic note itself.
b) At other times the subdivisions are veiled in mystery, hidden in the smooth legato of the phrase, and are perceived intuitively through the context.
c) In most cases, however, these secondary subdivisions disappear utterly, absorbed in the flow of the legato phrase and in the powerful undulations of the music as a whole. The ictic "touch" is then so tender, so caressing, as to become imponderable, a spiritual rather than a material force. The interior sense alone perceive it, if it be perceived at all.

The student should begin by giving the ictus a delicate shade of emphasis that can be heard. It will serve to sustain the voice as it passes from note to note. Gradually he should diminish the force of the ictus until, finally, it disappears materially, remaining merely a mental support, an intuition, a feeling for form.
But it's still taught at the Chant Intensives.
THE SOLESMES METHOD
Free Musical Rhythm
PART I
FUNDAMENTAL PRINCIPLES
What are the fundamental principles of the Solesmes Method? Here they are, and merely to state them will show how greatly they differ from those of speech rhythm.
1) Gregorian rhythm is specifically of a musical nature and is not the rhythm of speech.
2) Every step in the rhythmical synthesis is clearly defined: (a) the indivisible primary beat; (b) elementary rhythms and binary and ternary compound beats; (c) composite rhythms.
3) There is complete independence of rhythm and stress.
4) Hence there is complete independence of the rhythmic ictus and the tonic accent, and rhythm which is entirely free in its movement.
5) The words are subordinate to the melody.
6) Traditional interpretation and expression are followed. These are based on the concordant evidence of the oldest manuscripts.
I shall take up each of these points briefly, since I cannot give them the full treatment they require here.
5. The words are subordinate to the melody.
I have always appreciated semiological scholarship, but it just seems a bridge too far when you have limited time and must work with mostly non-musicians.
