Among the collection of marches constantly used in the Prussian army, is one composed by Frederick-William III. in 1806, which occupies a place between that of Frederick the Great, written in 1741, and the well-known Dessauer march. In that very same collection are the so-called _"Geschwind Marsch," No. 148, for infantry_, the _"Parade Marsch" No. 51, for cavalry_, and the _"Marsch Für Cavallerie" No. 55_, which emanate from the pen of Princess Charlotte of Prussia, niece of old Emperor William, and first wife of the present reigning Duke of Saxe-Meiningen. It is doubtless from her that Prince Bernhardt of Saxe-Meiningen, married to the eldest sister of the present kaiser, has inherited his powers of composition, for his name figures on the title page of many a piece of music; and among his other more important works has been the setting to music of _"the Persians of Aeschylus,"_ which has been most successfully staged at Athens. This is published under the initials of _"E.B." (Erbprinz Bernhardt)_. Though King Frederick-William IV. did not himself add anything to royal musical literature, as did his predecessors on the throne, he devoted much attention to ecclesiastical melody and song. The Berlin cathedral choir of men and boys--trained to sing without musical accompaniments--owes its origin to his ambition for having a choir in his own Protestant basilica at Berlin, corresponding more or less to the Pope's in the Sistine Chapel of Rome. It was he who engaged Mendelssohn as director of this choir, as well as composer; and it was the latter's successor, the director of the music of the Chapel Royal at the Prussian court, who compiled a collection of volumes containing settings of many of the Psalms of David, most beautifully arranged.
