Gregorian Chant
Propers from the 'Graduale Romanum' · Mass for the Feast of the Immaculate Conception

Gregorian Chant, the monophonic (Latin) ritual melody of the Roman Catholic Church, draws its name from Pope Gregory I, by whom it was collected and codified around the year 600. From Rome, and probably through its early adoption in Franconia, the chant became widely established with state approval in the ninth century in the singing schools (schola cantorum) of cathedrals and monasteries. The term Gregorian Chant is generally synonymous with Plainsong (Plainchant) and as the 'Cantus choralis' (i.e. the music sung 'in choro' — in the choir / chancel, by the altar), became in the Germanic lands, the 'Choral'. This implies that it was not sung by all present. The repertory of Gregorian Chant in current use is set out in the 1974 Graduale Romanum. The earlier sections comprise the melodies for those parts of the Mass which vary according to the church calendar, to underline the character of a season, feast or saint's day. This is the Proper (Proprium) as distinct from the musically and textually unvarying Ordinary (Ordinarium): Kyrie, Gloria, Sanctus, Agnus Dei.

The melodies do not conform to the familiar major-minor key system, but to that of the church 'tones' or 'modes'. The varying place of the semitones within the scale determines the character of a mode, and each mode was considered to have a different ethical / moral effect on singers and congregation. The especially important notes within an ecclesiastical mode are the final note (Finalis), the reciting note (Tuba or Repercussa), and the Tenor (sustaining note), which lies a fifth above the Finalis and around which the Psalm melody moves. Finalis and Tenor determine the modes and its expressive character. There are eight of these church modes (Dorian / Hypodorian; Phrygian / Hypophrygian; Lydian / Hypolydian; Mixolydian / Hypomixolydian). The seventh, the Mixolydian, was held to be radiant and festive and the sixth, the Hypolydian, warm-hearted and introspective.

For all the wealth and diversity of Gregorian Chant, certain formal principles may be recognised — the 'Parallelismus membrorum' and the arch form. The first comes from the nature of the prayer and meditation in the Psalms. In 'parallel' texts, each of the two halves of a Psalm verse illuminates and balances the other by expressing a similar idea in different words or a different idea in similar words (Sanctus, sanctus, sanctus, Dominus, Deus, Sabaoth). This textual 'Parallelismus membrorum' is also reflected in the music in the form of two or more melodic arches within the chant. In the case of longer texts or more extended chants, a rest point (flexa) is inserted half-way in each arch; a long chant might comprise Initium, Recitation, Flexa, Recitation, Mediation; Initium, Recitation, Flexa, Recitation, Terminatio.

In addition to 10 chants from the Proper, appropriate to different Sundays, this recording includes a complete choral office for the Feast of the Immaculate Conception, which has been observed since December 8, 1854. The Catholic dogma does not refer to the conception and birth of Christ, but asserts that the mother of Jesus was without original sin and that Jesus was conceived without blemish. The Introit and Communion are processional chants, which accompany respectively the entry of the celebrants at the start of the Mass and the defile of the congregation to Communion. The Alleluia and Gradual are meditational; the almost theatrical and virtuosic Offertory is notably for a near absence of recitation. The Antiphon 'Salve Regina' hails the mother of the Lord before the departure of the congregation. All the chants make it clear that the synthesis of sagacity, dedication, discipline, devotion, and fervour fosters the kind of singing that Bishop Ambrose of Milan designated 'sobria ebrietas' (sober intoxication).
