The music to the Forty-second Psalm, familiarly known by the caption which forms the title of this sketch, was first performed at the tenth subscription Gewandhaus concert in Leipsic in 1838, Clara Novello taking the soprano part. Though not constructed upon the large scale of the "Hymn of Praise," or even of the "Walpurgis Night," it is a work which is thoroughly artistic, and just as complete and symmetrical in its way. It contains seven numbers. After a slow and well-sustained introduction, the work begins with a chorus ("As the Hart pants after the Water Brooks, so panteth my soul for Thee, O God") which is a veritable prayer in its tenderness and expression of passionate longing. After the chorus a delicate and refined soprano solo ("For my Soul thirsteth for God") continues the sentiment, first given out in an oboe solo, and then uttered by the voice in a beautifully melodious adagio. The third number is a soprano recitative ("My Tears have been my Meat") leading to a chorus in march time by the sopranos and altos ("For I had gone with the Multitude; I went with them to the House of God"). Then follows a full chorus beginning with male voices in unison ("Why, my Soul, art thou cast down?"), answered by the female voices ("Trust thou in God"). Again the soprano voice is heard in pathetic recitative ("O my God! my Soul is cast down within me; all Thy Waves and thy Billows are gone over me"). A beautiful quartet of male voices with string accompaniment replies: "The Lord will command His Loving-kindness in the Day-time; and in the Night His Song shall be with me, and my Prayer unto the God of my Life." The response is full of hope and consolation; but through it all runs the mournful strain of the soprano (forming a quintet at the end), coming to a close only when the full chorus joins in a repetition of the fourth number ("Trust thou in God"), this time elaborated with still greater effect, and closing with a stately ascription of praise to the God of Israel. The Gutenberg Fest-Cantata. The occasion for which the short festival cantata known as the "Gutenberg" was written, was the fourth centennial celebration of the art of printing, which was observed at Leipsic in 1840 by the unveiling of Gutenberg's statue in the public square, and other ceremonies. The direction of the musical part of the festivity was intrusted to Mendelssohn. The text for the hymn to be sung at the unveiling, which occurred on the morning of June 24, immediately after the public service in Church, was furnished by Adolphus Prölsz, a teacher in the Gymnasium at Freiberg. Lampadius, in his Life of Mendelssohn, says of the performance:--
