As the entire six parts are very rarely given, a general review of their character will better suit the reader's purpose than a detailed review of each. When it has been performed in this country, only the first two parts have been given; while in England, though it has been presented entire, the performance is usually confined to the first three, which contain a complete story. The entire vocal score embraces no less than sixty-four numbers,--which in itself constitutes a sufficient reason for abridgment. In the first three parts the connecting narratives, recited by the evangelist, are assigned to tenor and bass, and declare the events associated with the birth of our Lord,--the journey to Bethlehem, the birth in the manger, the joy of Mary, and the thanksgiving over the advent of the Lord,--the choral parts being sung by the shepherds. The fourth part, that for New Year's Day, relates the naming of Jesus, and follows his career in a grand expression of faith and hope. The fifth part illustrates the visit of the three kings, the anxiety of Herod when he hears of the advent of the Lord, and the assurances given him to allay his fears. In the sixth section the visitors depart to frustrate Herod's designs, and choruses of rejoicing over the final triumph of the Lord close the work. In his voluminous life of Bach, Spitta makes an exhaustive analysis of the various parts, an abridgment of which will be of interest in this connection. The only variation from the particular character of each section is to be found in the introduction of the first chorale in Part I. at the close of Part VI., in the form of a brilliant choral fantasia. "In the first three the Christmas feeling prevails most vividly; this is effected in great measure by the chorales which are interspersed in far greater numbers than in the last three, and which are almost all familiar Christmas hymns. Most of them are simply set in four parts, with highly ingenious applications of the church modes." The first and second parts close with chorales, but in the third the opening chorus is repeated at the close. "Part IV. has least of the character of church festival music. The Biblical matter consists of a single verse from the Gospel of Saint Luke, ii. 21, which relates the circumcision and naming of Jesus. Not much material could be worked out of this, and Bach has almost entirely set aside all adjuncts from the liturgy. No Christmas hymn, indeed no true chorale, is introduced in it.... This section, therefore, bears more strongly the stamp merely of a religious composition; it is full of grace and sweetness, and can only have derived its full significance for congregational use from its position in context with the rest of the work." Parts V. and VI., devoted to the history of the three kings, are in no respect inferior to the first three.
