"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 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 paeans of praise, not even a hallelujah at its close.
