The Appearance of the Singer and the Bocca Ridente

Tosi’s directions regarding the singer’s presence continue and refine the tradition expressed earlier in the seventeenth century by Italian writers and commentators on the subject. These include Francesco Durante, Marco da Gagliano, Girolamo Diruta, Pietro Cerone, Orazio Scaletta, Giovanni Battista Doni, and Ignazio Donati, whose caveats were directed largely against bodily and facial contortions and mannerisms that would detract from the singing. Tosi advocates a noble bearing (graceful posture) and an agreeable appearance; he insists on the standing position because it permits a freer use of the voice; further, he warns against bodily contortions and facial grimaces, which may be eliminated, he says, by periodic practice in front of a mirror. He recommends that if the sense of the words permit, the mouth should incline “more toward the sweetness of a smile than toward grave seriousness.” In short Tosi recommends the bocca ridente, which requires not only a “smiling mouth,” but also a positioning of the vocal apparatus critical to the bel canto style.

Vibrato

There are several mechanisms in the human voice for producing vibrato. One of these occurs in the same manner as the trill, that is, by the up-and-down movement of the larynx in a manner less exaggerated than the trill. Vibrato was considered an inseparable feature of the human voice in the seventeenth century. It is very difficult, for example, for a singer to execute a messa di voce or crescendo totally without vibrato. An important clue regarding this phenomenon is the vox humana stop in Spanish and Italian organs, which was always a trembling stop, as early as the 1500s. Yet this does not necessarily mean that vibrato was constant. In the twentieth century a concept of singing as a string of “beautiful pearls” developed. This is very different from the seventeenth-century aesthetic, in which the finest singers could alter their technique and their sound in order to adapt to the musical or dramatic context.

Singers today modify their technique so that the placement, color, and timbre of a note matches exactly the note before and after it, the textual or dramatic context notwithstanding. There are certain situations in which a seventeenth-century singer would have sung without vibrato—perhaps on a dissonance, a leading tone, in a
messa di voce crescente (a glissando within a half step), or on a particularly expressive interval such as a tritone. While consistent vibrato can homogenize the sound on all notes of the singers range, it does not allow for a demonstration of harmonic intelligence and expressivity that a seventeenth-century singer would have demanded. The disposizione della voce—the ability to sing fast notes in a glottal fashion—was a highly admired and necessary skill for the professional singer. This light, almost giggling technique, audible in the more intimate performing spaces of the seventeenth century, surely contributed to a softer volume and to a faster vibrato, since coloratura speed and vibrato speed are interrelated.

The Appoggiatura

Tosi devotes an entire chapter to the appoggiatura and recommends practicing this ornament in scalar passages, with an appoggiatura on each step of the scale. Agricola, strongly favoring on-beat execution of the appoggiatura, is careful to stress that the location of the syllable or word of the text underlay should occur on the appoggiatura itself rather than on the main note under which it is habitually written: “when a syllable falls on a main note, which itself is notated with an appoggiatura or any other ornament, then it [the syllable] must be pronounced on the appoggiatura.” Agricola’s rule referring to the on-beat performance of the appoggiatura must be understood in the context of earlier Baroque practice, in which the phrase anticipatione della syllaba referred to a situation in which an appoggiatura or a onenote grace similar to it actually preceded the beat and bore the syllable.

Diction

Tosi has a great deal to say about diction, and much of it pertains to the singing of divisions:

Every teacher knows that the divisions sound unpleasant on the third and the fifth vowels (the i or the u).10 But not everyone knows that, in good schools, they are not permitted even on the e and o if these two  vowels are pronounced closed. . . Even more ridiculous is when a singer articulates too loudly and with such forceful aspiration that, for example, when we should hear a division on the a, he seems to be saying ga ga ga. This applies also to the other vowels.

Some earlier Italian writers, such as Camillo Maffei, said that the u vowel sounded like howling, especially since the Italian word for howling is ululando. The i was rejected because it was thought to produce the sounds made by small animals. Agricola is critical of basses who, when singing divisions, “put an h in front of every note, which they then aspirate with such force that, besides producing an unpleasant sound, it causes them unnecessarily to expend so much air that they are forced to breathe almost every half measure.

The Bel Canto Singing Style (I)

Of the various national styles of singing in the Baroque era, the Italian style was the mainstream. There has been a more or less unbroken tradition of bel canto singing ever since Giulio Caccini wrote about it in his Le nuove musiche (1602). The classical bel canto style crystallized in the late seventeenth century, when musical considerations triumphed over the text-dominated style of the early part of the century. By that time Italian opera had become something of a commodity, and Italian signers were in demand throughout Europe. Unfortunately, for about the last three quarters of the century there are essentially no Italian treatises on singing. There are, to be sure, numerous treatises from German writers of this period, but while they were enthusiastic admirers of the Italian style, few of them had direct association with bel canto singers. Pier Francesco Tosi, a castrato singer and actor of some note, was, however, thoroughly conversant with the bel canto style. His Opinioni de’ cantori antichi, e moderni was published in 1723, chronologically beyond the limits of this guide, but by that time Tosi was well into his seventies. His ideas about singing were formed during the closing decades of the seventeenth century, when he was at the height of his career. Moreover, the title of the book clearly indicates Tosi’s awareness of the “ancient”—by which he means the style of his own heyday as a singer—and the “modern” styles of singing, and it is clearly the former that he prefers. Tosi’s treatise was translated into English by J. E. Galliard (1743) and into German by J. F. Agricola (1757). The latter’s copious annotations are often quite illuminating, even for seventeenth-century practice, in spite of their late date.
