After a short prelude, the second part opens with a tenor aria for Abadil ("O, thou my Star") which is very refined in sentiment. It is followed by the chorale "Jesu, dulcis Memoria," sung by the chapel choir. A duet ensues between the two lovers on the castle terrace, which is very Italian in its flavor, and one of the most effective numbers in the cantata. The next two numbers furnish the wedding music,--a happy bridal chorus, and a charming bolero for orchestra. These lead to an unaccompanied quartet between Don Munio, Donna Maria, Abadil, and Constanza ("It is the Lot of Friends to part"). In the next scene occurs a vigorous duet between Don Munio and his wife, in which he informs her of his speedy departure for Palestine, followed by a stirring battle-hymn for male chorus. The next scene, "The chapel of the castle, choir chanting the dirge for the dead," is in strong contrast with the preceding. Mr. Buck has rarely written anything better in his sacred music than this beautiful requiem. In the next two numbers the messenger describes the manner of Don Munio's death, and the ghostly vision at the sepulchre, and at the end of his message the requiem changes to a jubilant chorus of gratitude ("In thankful Hymns ascending"). "Don Munio" is one of the most powerful and spontaneous of American compositions, and needs but little more amplification to deserve the name of opera. The Centennial Meditation of Columbia. The National Centennial celebration at Philadelphia was inaugurated May 10, 1876, with a special musical programme, in which the cantata with the above formidable title occupied a prominent place. The ode was written by Sydney Lanier, of Georgia, a poet who prior to that time had made considerable reputation by two poems printed in "Lippincott's Magazine." The national idea was satisfied by assigning the music to Dudley Buck, at that time living in Connecticut. It must be acknowledged that the work did not make a deep impression, although it contains some excellent musical writing, and for two sufficient reasons. First, it is not a work of musical genius or inspiration, as it was ordered by a commission for a popular show. It was not singular in this respect. The "Centennial March," written by Richard Wagner, for the same occasion, is page after page of sound and fury, executed for a most exorbitant remuneration. To ascertain its real want of inspiration one has but to place it by the side of the "Kaiser March," with its massive chords, its grand thematic treatment, and its stately movement, the outcome of patriotic fervor and national triumph. Second, the stilted and unmusical lines furnished by Mr. Lanier must have hampered the composer in every verse. This is all the more remarkable because Mr. Lanier himself was a practical musician. He had been for some time a violinist in the Peabody orchestra at Baltimore, under that accomplished leader, Asgar Hamerik. It is
