On April 25, 1843, the general returned, accompanied by Madame Lascours and all the officers of his staff. The following was the programme of the occasion: (1) A quartette from Webbe; (2) A Languedoc air in three parts, from Desrues; (3) A trio from the opera of _[OE]dipus in Colonna_, by Sacchini; (4) Singing at sight intervals of all kinds, major and minor; (5) Singing at sight in eight different keys; (6) Two rounds in three voices from Siller; (7) A quartette from the _Clemenza di Tito_ of Mozart; (8) A quartette from the _Iphigenia_ of Gluck; (9) A trio from the _Corysander_, or the _Magic Rose_ of Berton; (10) Exercise upon the tonic in all the keys, major and minor; (11) Exercise in naming notes vocalized; (12) Singing at sight a trio from the _Magic Flute_ of Mozart; (13) _Ave Regina_, by Choron--three voices; (14) The _Gondolier_, a round in three parts, by Desrues; (15) A quartette from the _Magic Flute_; (16) Chorus from the _Tancredi_ of Rossini; (17) The "Prayer" from _Joseph_, by Mehul. This is certainly a remarkable programme to be filled by illiterate soldiers with only six months' training. "It would be difficult," says the official report, "to paint the astonishment of the spectators upon this occasion. The confidence and readiness with which these soldier-students of music sang at sight the most difficult intonations, major and minor, the facility with which they read in all the keys, and, finally, the certainty and spontaneity with which they _all, without exception_, recognized and named various sounds vocalized, showed clearly that they possessed a very superior knowledge of intonation. All the pieces which they sung were rendered with irreproachable correctness, though the professor did not beat the time, except through the first bar to indicate the movement. "With the consent of General Lascours, all the teachers and professors in the city, including the members of the Royal College, were on one occasion admitted to a private rehearsal of M. Cheve's class. The result was the same--admiration and astonishment. The professor received on all sides well-merited praise for a success gained in so short a time and with such unfavorable conditions. "These soldiers have at this moment (September 1, 1843) reached a degree of power in intonation and in reading music at sight which is fairly wonderful. They can sing together at sight any new piece in three or four parts, the music being written, after the new method, in figures. If the piece be written in the ordinary musical character, no matter what the key, they can also sing it at sight together after they have together sung each part by itself. All the members of the class understand thoroughly the theory of music, and are able to write from dictation a vocalized air never heard before, no matter what the modulations may be.
