The passion is written in two parts, between which the sermon intervened in old times. It includes portions of chapters xxvi. and xxvii. of the Gospel according to Saint Matthew, the remainder of the text being composed of hymns furnished to Bach by Christian Friedrich Henrici, who wrote under the pseudonym of "Picander," and, it is said, was assisted in the compilation by the composer himself. The dramatis personæ are Jesus, Judas, Peter, Pilate, the Apostles, and the People, or Turbæ, and the narrative is interpreted by reflections addressed to Jesus, forming two choruses, "The Daughter of Zion" and "The Faithful," as Picander calls them. They are sometimes given by the chorus, and sometimes by single voices. The chorales are selected from those which were in common use in the Lutheran Church, and were familiar therefore to the congregations which sang the melody, the harmony being sustained by the chorus and instruments. The Gospel text is in recitative form throughout, the part of the evangelist, or narrator, being assigned to a tenor voice, while those of the persons incidentally introduced are given to other singers. In the dialogue, wherever the words of Jesus occur, the accompaniment is furnished by a string quartette, which serves to distinguish them from the others, and invests them with a peculiar gentleness and grace. The incidental choruses, sung by the People and the Apostles, are short and vivacious in character, many of them being in madrigal form. The chorales, fifteen [42] in number, as has already been said, were taken from the Lutheran service. One of them, which Bach also liberally used in his "Christmas Oratorio," beginning, "Acknowledge me, my Keeper," appears five times in the progress of the work, forming the keynote of the church sentiment, and differently harmonized on each occasion. Another, "O Blessed Jesus," is twice used,--once where the Saviour announces that he will be crucified after the Feast of the Passover, when the whole congregation sings it, and again in the scene at Gethsemane, sung by select choirs. The whole work is written for double chorus, the two choruses singing the harmony of the chorales, accompanied by the instruments, while the congregation sing the tune in unison. They display to the utmost the breadth, richness, ingenuity, and power of Bach in this form of writing. The reflective portions of the work, the text written by Picander, are composed of arias introduced by recitative, with the first part repeated in the close; of arias accompanied by chorus; and of single choruses constructed in the most massive manner. Speaking of the melodies in these portions of the work, Spitta says,--

"The grades of feeling traversed by Bach in the solo songs of the 'St. Matthew Passion' are all the more impressive because every sentiment of joy in its various shades is wholly excluded; they are all based on the emotion of sorrow. The most fervent sympathy with the sufferings of the Son of Man, rising to the utmost anguish, childlike trustfulness, manly [43] earnestness, and tenderly longing devotion to the Redeemer; repentance for the personal sins that his suffering must atone for, and passionate entreaties for mercy; an absorbed contemplation of the example offered by the sufferings of Jesus, and solemn vows pronounced over his dead body never to forsake or forget him,--these are the themes Bach had to treat. And he has solved the difficult problem as if it were child's play, with that inexhaustible wealth of resource which was most at his command precisely when he had to depict the sadder emotions. In no other of his works (unless it be in the 'Christmas Oratorio') do we find such a store of lovely and various solo airs, nor did Bach even ever write melodies more expressive and persuasive than those of the arias in the 'St. Matthew Passion.'"

As we have said, the music is arranged for double chorus, and each chorus has its own orchestra and its own organ accompaniment. The double orchestra is composed of oboes, flutes, and stringed instruments. Drums and brass instruments are not used, the sentiment of the work, in Bach's estimation, not being fitted for them, sweetness and expressiveness of tone rather than power being required. As Spitta says, sorrow is the characteristic of the work. It has no choruses of rejoicing, no pæans of praise, not even a hallelujah at its close.

The first part opens with a reflection sung by double chorus, "Come, ye Daughters, weep for Anguish," the first exhorting believers to weep over the sinful world, the second responding with brief interrogations, and at last taking part in the [44] sorrowful strains of the first. Interwoven with these is an independent instrumental melody, the whole crowned with a magnificent chorale sung by the sopranos, "O Lamb of God all blameless!" followed by still another, "Say, sweetest Jesus," which reappears in other parts of the work variously harmonized. The double chorus and chorales form the introduction, and are followed by recitative and a chorale, "Thou dear Redeemer," and a pathetic aria for contralto, "Grief and Pain," relating the incident of the woman anointing the feet of Jesus. The next number is an aria for soprano, "Only bleed, Thou dearest Heart," which follows the acceptance by Judas of the thirty pieces of silver, and which serves to intensify the grief in the aria preceding it. The scene of the Last Supper ensues, and to this number Bach has given a character of sweetness and gentleness, though its coloring is sad. As the disciples ask, "Lord, is it I?" another chorale is sung, "'Tis I! my Sins betray me." Recitative of very impressive character, conveying the divine injunctions, leads up to a graceful and tender aria for soprano, "Never will my Heart refuse Thee," one of the simplest and clearest, and yet one of the richest and most expressive, melodies ever conceived. After further recitative and the chorale, "I will stay here beside Thee," we are introduced to the scene in the Garden of Gethsemane, which is characterized by a number of extraordinary beauty and strength in its construction. It is introduced by a short instrumental [45] prelude, Zion, represented by the tenor voice, and the Believers by the chorus, coming in after a few bars and alternating with extraordinary vocal effect. It calls for the highest dramatic power, and in its musical development is a web of wonderful harmonies such as we may look for only in the works of the mighty master of counterpoint. It fitly prepares the way for the two great movements which close the first part, an aria for soprano and alto, "Alas! my Jesus now is taken," and a double chorus, "Ye Lightnings, ye Thunders!" The two solo voices join in a lament of a most touching nature, accompanied by the chorus exclaiming in short, hurried phrases, "Let Him go! Hold! Bind Him not!" until at last the double chorus bursts in like a tempest, accompanied with the full power of the instruments, expressing the world's indignation at the deed which is to be committed, in the words:--

"Ye lightnings, ye thunders, in clouds are ye vanished!

Burst open, O fierce flaming caverns of hell!

Ingulf them, destroy them in wrathfullest mood!

Oh, blast the betrayer, the murderous brood!"

and the first part concludes with a chorale, "O Man, bewail thy great Sin!"

The second part, originally sung after the sermon, opens with an aria for contralto, full of the deepest feeling, "Alas! now is my Jesus gone," and one of the most beautiful numbers in the oratorio, [46] wherein Zion, or the Church, mourns her great loss. The trial scene before Caiaphas and the threefold denial of Peter follow, leading up to the beautiful aria for alto, with violin obligato, "Oh, pardon me, my God!" Macfarren, in his admirable analysis, says of this aria,--

"The deep, deep grief of a tormented conscience finds here an utterance which fulfils the purport and far transcends the expression of the words. One might suppose the power of the artist to have been concentrated upon this one incident, so infinite is its beauty,--one might suppose Bach to have regarded the situation it illustrates as more significant than others of man's relation to Deity in his sense of sin and need for mercy, and as requiring, therefore, peculiar prominence in the total impression the oratorio should convey. If this was his aim, it is all accomplished. The penitential feeling embodied in the song is that which will longest linger in a remembrance of the work. The soft tone of the contralto voice, and the keenness of that of the violin, are accessories to the effect which the master well knew how to handle; but these judicious means are little to be considered in comparison with the musical idea of which they are the adjuncts."

The work now rapidly progresses to its beautiful finale. The soprano recitative in response to Pilate's question, "He hath done only good to all," the aria for soprano, "From love unbounded," the powerful contralto recitative, "Look down, O God," the chorale, "O Head all bruised and wounded!" the contralto aria with chorus, "Look [47] where Jesus beckoning stands," and the peaceful, soothing recitative for bass, "At Eventide, cool Hour of Rest," are the principal numbers that occur as we approach the last sad but beautiful double chorus of the Apostles, "Around Thy Tomb here sit we weeping,"--a close as peaceful as the setting of the sun; for the tomb is but the couch on which Jesus is reposing, and the music dies away in a slumber-song of most exalted beauty. This brief sketch could not better close than with the beautiful description which Mr. Dwight gives of this scene in the notes which he prepared when the work was performed at the Triennial Festival of the Handel and Haydn Society of Boston:--

"How full of grief, of tender, spiritual love, of faith and peace, of the heart's heaven smiling through tears, is this tone-elegy! So should the passion-music close, and not with fugue of praise and triumph like an oratorio. How sweetly, evenly, the harmony flows on,--a broad, rich, deep, pellucid river, swollen as by countless rills from all the loving, bleeding, and believing hearts in a redeemed humanity! How full of a sweet, secret comfort, even triumph, is this heavenly farewell: It is 'the peace which passeth understanding.' 'Rest Thee softly' is the burden of the song. One chorus sings it, and the other echoes 'Softly rest;' then both together swell the strain. Many times as this recurs, not only in the voices, but in the introduction and frequent interludes of the exceedingly full orchestra, which sounds as human as if it too had breath and conscious feeling, you still crave more of it; for it is as if your soul were bathed in new life inexhaustible. [48] No chorus ever sung is surer to enlist the singers' hearts."
