Baini, who in the early part of this century was the successor in office of the great composer, being musical director of the papal choir at Rome, was probably the ablest and most enthusiastic student of the works of Palestrina that ever existed, and his great work, "Memorie storicho-critiche della vita e delle opere di Giovanni Pierluigi da Palestrina" (Rome, 1828. Two volumes), spite of a degree of partisanship and consequent lack of appreciation of the work of some of the Flemish composers, will probably always remain the bucket through which the waters of the well of Palestrina are best attainable. No man ever had as good opportunities of access to the master's works, and no one could have employed those opportunities better. He, with extreme exactness, classifies the works of the master into ten groups or styles. It would be both unnecessary and prolix to follow him through all of these; more practical for the general musician is the summing up of Hauptmann (whose essay is founded on Baini), who says, "Baini's ten styles may become bewildering to many, but three styles of composition may be readily recognized on close acquaintance with his works. In the first style he approaches the school of his predecessors the Netherlanders (the Flemish school), and this is shown to our ears by a lack of harmony; the melodies go on their course beside each other, without blending into harmonious unity; harmonically judged they are dry, heavy, and inflexible, and they are continuously canonic or fugated. The second style is, on the contrary, in simultaneous progressions, like our chorales. Here the voices are, as a matter of course, always singable, but the conditions of the melody are, as the harmonies of the preceding, rather negative, and the composer is not turned aside by any ill-sounding effects. The third style is the uniting of the foregoing two in the best and most beautiful manner that can be achieved in this sphere, and it is this school that has placed Palestrina in so high a rank for all time; in this style is the Mass of Pope Marcellus composed. There are however, beautiful specimens of the second style in existence, as, for example, the Improperia, which always refreshes me by its simplicity."
In the use of chorale-like simplicity, Palestrina causes the commentator involuntarily to draw a comparison between him and John Sebastian Bach. The parallel could be drawn more closely than many of the ancient ones of Plutarch, for not only were both composers polyphonic in their musical vein, but both were actuated by the sincerest religious feeling in their largest compositions. Palestrina may stand as the typical Catholic, as Bach represents the earnest Protestant, in music.
Unquestionably the earliest vein of Palestrina's composition was influenced by his Flemish training, and he returned to this florid and ingenious style in later time when he set the old melody of "L'Homme Armé" as a Mass. This was a very natural proceeding. We have alluded above to the custom of setting masses around a secular core, using some popular melody as cantus firmus, as practised by the Netherlanders. When Palestrina chose the above-named melody, he entered deliberately into the lists with them; so many of his predecessors had used the self-same cantus that "L'Homme Armé" became in some degree a challenge and a specimen of competitive composition; skill and complexity were to rule in such a mass, and it is sufficient to say that Palestrina overtopped his competitors in these, and therefore the object of this work was attained. It may stand as the best example of the first school.
The Improperia are a series of antiphons and responses which, on the morning of Good Friday, take the place of the daily Mass of the Catholic church. They represent the remonstrances of the suffering Savior with the people for their ingratitude for his benefits, whence the title "Improperia," i. e. "the Reproaches." We have stated that the old pure school did not portray emotion in the modern style; one may not find in these "Reproaches" of Palestrina the entirely human style of a Luzzi's "Ave Maria" or the operatic manner of a Rossini's "Stabat Mater," but the simple combination of dignity with sorrow is nevertheless far more effective and suitable to the religious service; it is therefore not surprising to find these Improperia (the first revelation of the genius of Palestrina) still retained in annual use in the Papal Chapel, and we may class them as Hauptmann did, as the best example of Palestrina's second manner. Mendelssohn held them to be Palestrina's most beautiful work, and the poet Goethe was also greatly moved by them.
The Mass of Pope Marcellus has been cited as the best example of the master's third style, and at the same time the culmination of his powers. This Mass is in the so-called Hypo-Ionian mode (although the "Crucifixus" and "Benedictus" are Mixo-Lydian), and is probably the noblest example of the employment of the church modes in the pure style. Although the work is most intricate, Palestrina has here achieved that most difficult feat, the art of concealing art. It presents all the old fugal artifices, and the "Agnus Dei" is a close and ingenious canon. It is written for six voices, soprano, alto, two tenors, and two basses. This in itself was an unusual combination of voices and gave opportunities for great antiphonal effect, between the lower voices, and these opportunities are so well used that the effect of a double choir is frequently attained.
Baini calls the "Kyrie" devout; the "Gloria" animated; the "Credo" majestic; the "Sanctus" angelic; and the "Agnus Dei" prayerful; but it is doubtful if the modern auditor will perceive all these distinctions in listening to the work. Of its dignity and loftiness, however, there can be no question. One can observe readily how close to the composer's heart was the injunction that the words should be clearly understood; in the most important phrases we find counterpoint of the first order (note against note), while in passages where the same words are often repeated Palestrina employed the most beautiful contrapuntal imitations. The voices are so interwoven that wonderful chords greet us in almost every phrase, yet so free from unnecessary dissonance are these, and so clearly founded on the progressions of the triads, that the effect of simplicity is attained even in the midst of the displays of greatest musical skill. It is true that one can find effective chords in the works of the Flemish school, but on examining these closely it will be seen that they have been "filled in," and do not arise spontaneously from the contrapuntal progressions, while with Palestrina the leading of the voices is never disturbed in the slightest degree for the sake of the chord-formation, but all the harmonic effects grow out of the melodic construction of the various parts, or of the musical imitations introduced between the voices. It remains to be stated that the great musical historian Ambros has thrown doubt upon the origin of the Mass just described, and asseverates that not only was it not written as a model at the request of the committee of cardinals, but that there was really no occasion for any especial reform in the matter of church music at the time that it was produced. The weight of authority and the consensus of opinion, however, are here entirely against the eminent German scholar, and the facts as above stated are now almost universally conceded.
In all of Palestrina's church music one cannot fail to notice that he discards the chromatic progressions which his predecessors and contemporaries used so freely; he did this from a devout desire to keep the church modes intact, and if at times, because of this self-denial, he lost some effects of emotional display, on the whole his works gain much in purity and dignity in consequence.
If in Palestrina's Masses we find the beginning of chord-effect, the true principles of harmonic beauty, in his motettes and madrigals one can discern the first masterly touches of the employment of rhythm. Rhythm could only reach its true culmination in the homophony which came at a later epoch, but one can trace a distinct effort in this direction in the shorter and lighter works of the master, who thus may be regarded as a connecting link between the old and the new schools.
In the matter of the old triad-construction of his chords, however, he was inflexible; Des Prés and Di Lasso might use dissonances to express passion, but he held this kind of passion as too human to enter into his pure church-music. Monteverde soon after brought in the free use of the seventh-chords, yet the careful student will find these slyly introduced in many a work of the 16th century; he will however, find few such attempts in Palestrina.
