The motet
Egregie Doctor Paule, for the Feast of the Conversion of St. Paul, is notable for demonstrating Sumaya's musical education. The
prima pars was composed by Salazar, while the
secunda pars is by Sumaya. There are subtle yet noticeable differences between the two composers' work, with Sumaya's being more likely to engage in harmonic daring and less-common chord voicings and resolutions. Such colorful harmonies were becoming more common in Spain as Italian treatises and compositions spread throughout the kingdom. The 1738 edition of José de Torres' figured bass treatise refers to them as
posturas falsas and
posturas extravagantes. Posturas falsas include chords involving chromatic alterations, including what are today regarded as dominant seventh and fully-diminished seventh chords. Posturas extravagantes refer to any chord involving the simultaneous use of the minor third and augmented fourth, or any chord that includes the less common sonorities of the minor second and major seventh. Sumaya's villancico
El sol-fa de Pedro, written as part of his
examen de oposición (audition) for the post as
maestro de capilla of Mexico City Cathedral, is an example of a
villancico de precisión. In such a villancico, the composer demonstrates his compositional prowess and musical erudition through the musical setting of a text containing puns and wordplay related to musical terms. As Christ was often associated with the Sun in such texts, this technique applied to the word "sol" (sun) was common. For example, in an F-based tonality, the pitch C (the fifth scale degree, "sol" in solfège) would be associated with the word "sol" (sun). The cantata
Si ya a aquella nave, for the Feast of St. Peter, is one of Sumaya's most Italianate works. Set for alto voice accompanied by two violins and basso continuo, it is notable for its use of text painting. Perhaps the most notable instance is in the first da capo aria ("Prosigue, prosigue al mismo correr"). Sumaya alters the typical ABA formal scheme by appending to the B section a highly chromatic passage involving the bass descending chromatically over nearly two octaves, with the violins providing an accompaniment of falling figures that vividly portrays the words "llanto" ("weeping") and "morir" ("to die"). The bass line emphasizes every fourth note as it descends, articulating a series of descending chromatic tetrachords in a characteristic lamento bass pattern.
Ya se eriza el copete, for the Feast of
Our Lady of Guadalupe, is a notable example of a more traditional villancico in the style of Salazar or Hidalgo. It is set for two choirs—a solo tenor with basso continuo, a choir of soprano, alto, and tenor with its own basso continuo—and a general accompaniment part. The estribillo, which uses mensural notation, has a text that poetically describes the Guadalupe apparition turning the snowy cold of December (the feast date is December 12) into the flowers of May, a month typically associated with the Virgin Mary. The coplas, written in more modern notation, elaborate on this and tie the villancico more closely to Mexico City with references to
St. Juan Diego and the
maguey plant. The large-scale Italianate villancicos
Celebren, publiquen;
Angélicas milicias; and
Albricias, mortales are among Sumaya's most often-performed works. All three are for Marian feasts; the first two are for the
Feast of the Assumption and the third for the
Feast of the Immaculate Conception.
Celebren, publiquen and
Albricias, mortales call for one choir of alto and bass soloists with their own basso continuo and a second choir of soprano, alto, and tenor with its own basso continuo. Both of these use an instrumental complement of violins, trumpet, and basso continuo.
Angélicas milicias is even larger-scale, set for two choirs of soprano, alto, and tenor, each with its own basso continuo, plus an instrumental complement of violins, viola, oboe, bassoon, and basso continuo. All three are notable for their use of text painting and instrumental color, with violins depicting the twittering of birds in
Albricias, mortales and repeated notes in the oboe calling to mind trumpet calls in
Angélicas milicias. In spite of the outwardly Italianate style of all three pieces, the harmonic structure, erudite texts, and polychoral setting reveal their Spanish core. ==References==
