The form adopted by Saint-Saëns in his second concerto, op. 25, is sufficiently novel. Its first movement is labelled "Andante sostenuto," and commences with a long introduction for the piano, somewhat in the style of Bach. The passionate melody which succeeds to this, and may be considered as the principal theme of the movement, is, however, quite modern in character. The delightful "Scherzo" and inspiriting "Finale," are slightly suggestive of both Weber and Mendelssohn, whilst bearing the distinctive mark of their composer's personality. In his fourth concerto in C minor, op. 44, Saint-Saëns has departed still further from the usual model. This work is divided into two sections, which include five changes in the "tempo." A noticeable feature in the concerto is the reintroduction in the last movement of themes previously heard in the first, thus producing a sense of homogeneity. The fourth concerto is the most ambitious work of the kind that Saint-Saëns has written. It is also the best. A few years since, the composer attempted the experiment of performing all four works in succession at a concert given at the St. James's Hall. Saint-Saëns did not make his _début_ as an operatic composer until he had reached the age of thirty-seven, and then only with a one-act opéra-comique, entitled "La Princesse Jeaune," produced at the Opéra Comique Theatre in 1872. This curious little work, the scene of which is laid in China, was not well received and speedily disappeared from the bills. The overture is delightfully quaint, and is occasionally heard at concerts. Now that one-act works are coming into vogue, this delicate little score might well be reproduced. The reputation acquired by Saint-Saëns as a symphonist, and what is known in France as "un musicien savant," had been sufficient to cause any pretension on his part to aspire to the fame of a dramatic composer to be looked upon with suspicion. Added to this, he had the reputation of harbouring feelings of admiration for Wagner, which at that time was quite enough to prevent a manager from producing his works. An opera entitled "Le Timbre d'Argent," not to be confounded with Vasseur's operetta "La Timbale d'Argent," was written before the war of 1870, and was destined for the Opéra Comique Theatre. It was, however, not brought out until 1877, when it was played at the Théâtre Lyrique under the direction of Mons. A. Vizentini. The influence of Gounod is very apparent in this work, and Bizet even found therein certain affinities with Auber which I confess myself unable to discover. One thing certain is, that this opera has but little in common with Wagner. "Le Timbre d'Argent" reveals the hand of the practised musician, but is very unequal as a whole, and does not occupy an important place in the composer's dramatic outfit. A point to note in this opera is the superiority of the orchestral treatment and general workmanship over the melodies, many of which border upon the commonplace.
