Gigault published two collections of organ works. The first,
Livre de musique dédié а la Très Saincte Vierge of 1682, contains the earliest known examples of the French noël (a set of variations on a Christmas carol) and an
allemande. Gigault's 20 noëls include variations on Christmas songs and church hymns connected to Christmas. These pieces always progress from two-part to four-part settings and feature a somewhat rigid variation technique. In the preface Gigault suggests that these pieces can be performed on any instruments: i.e., on a pair of viols, or on a lute, etc. The solitary allemande bears no connection whatsoever to Christmas. It is presented in two versions, the second being set in "ports de voix", showing various common ornamentation patterns. Gigault's second collection, ''Livre de musique pour l'orgue'' of 1685, contains 184 pieces. It begins with three organ masses, which rely heavily on Mass IV melodies, like all other surviving French organ masses from the period. However, Gigault's contemporaries limited their use of the chant to
cantus planus settings, whereas in Gigault's masses chant melodies also appear paraphrased or transformed into fugue subjects, and form a very large proportion of the masses. The first and the third masses are large, each comprising more than 20 pieces, while the second mass is extremely short with just 7 versets. The rest of the collection is arranged by mode: there are numerous fugues (a fact mentioned in the preface) and also various typical French forms such as dialogues and récits. Also included are three hymns:
Pange lingua,
Veni Creator and a complete setting of the
Te Deum. Because the music of Gigault's second
Livre is more representative of the French style of the third quarter of the century, rather than the last, the collection may have been a compilation of earlier composed material. All major French forms are represented, although Gigault's way of naming them differs from his contemporaries: he uses the term "fugue" much more broadly (e.g., he uses "Fugue à 2" instead of "Duo"), never uses the term "dialogue", etc. The music is notated meticulously, with more attention to details of performance than in other contemporary sources. There is much use of
notes inégales, so much that some scholars believe the music to be unlistenable today, and in general, Gigault's work was judged negatively by most scholars. Nevertheless, the music is distinguished by a serious style, more suitable to the church than that of
Lebègue; Gigault's dialogues go beyond those of his contemporaries,
Nivers and Lebègue, in that they employ more divisions, and he also cultivates a number of five-voice genres: préludes and récits with pedal
cantus firmus in the tenor. Gigault's 1685
Livre was most probably meant as a record of Gigault's style, rather than a book for lesser organists; the music is at times quite sophisticated and requires a high degree of skill. ==Notes==
