His opening aria in the opera to be rehearsed was in the key of E flat. The orchestra played the introductory bars, and waited with a casual interest for the new singer's opening phrase. The tenor commenced, but, instead of doing so in the key in which they were playing, he began to sing a semitone higher, in E natural. At first they were horrified at the discords which resulted. Gradually, however, as the aria went on, and the vocalist still sang exactly a semitone above the key in which they were playing, it began to dawn upon them that, instead of being sharp through nervousness or lack of ear, he was keeping a half tone too high intentionally throughout the piece. Consequently, when they heard him continue in E natural, without a moment's hesitation, or a single false note (for so great a musician was he that he could abstract himself entirely from his surroundings and from the sound of the instruments), their disgust turned to surprise, then admiration, and finally enthusiasm. When the aria was concluded there was an enormous burst of applause and the wildest excitement among them all, for they saw what a really great singer they had found in this newcomer. Of course he sang the remainder of his part in the proper key, but by this novel entry he won the lasting respect of his comrades.
The anecdote afforded a good illustration of his exceptional powers. The elder Garcia was certainly a wonderful man, and in some ways a unique figure in the history of music, for it is doubtful if any other singer has duplicated his extraordinary talent and versatility. Attention has already been called to the fact that he was conductor and impresario. As a composer he was responsible for over forty operas, of which number seventeen were Spanish, nineteen Italian, and seven French; and in many cases he was even responsible for the libretto. The greater number of these works were performed in Spain, France, and America.
When he was in Paris "El Poeta Calculista" was given, as we have already said, with the greatest success in 1809, and three years later "The Caliph of Bagdad" received no less appreciation. His power as an actor was equal to that as a singer, while his Spanish temperament gave a fire to his impersonations which could not but awaken enthusiasm. "J'aime la fureur andalouse de cet homme," wrote a contemporary critic; "il aime tout."
But of all his qualities that which perhaps stood out most was a remarkable gift of extemporisation. It was this which first attracted the notice of Rossini, and led him to write the tenor rôle in "Elisabeth" for the elder Garcia. The result was so satisfactory that when he set to work on his next opera, "Il Barbiere di Seviglia," he wrote the part of Almaviva specially for him.
The story of this production, as Manuel Garcia related it, was an interesting one.
In the December of 1815 Rossini had bound himself to produce a new opera by the 20th of the following month. He hesitated at first about accepting a libretto which Paisiello had treated so successfully, but having obtained that composer's permission he wrote the entire score in a fortnight. To avoid all appearance of rivalry with Paisiello he named his work first of all, "Almaviva, or The Useless Precaution"; and it was accordingly produced under this title in Rome at the Argentina Theatre on February 5, 1816, with the following cast:—
| Rossini | Signora Giorgi Righetti. |
| Berta | Signorina Rossi. |
| Figaro | Signor Luigi Zamboni. |
| Bartolo | Signor Botticelli. |
| Basilio | Signor Vitarelli. |
| Count Almaviva | Signor Garcia. |
The theatre was packed with the adherents of the older composer, who resented the new effort as an intrusion on his rights. In consequence of this the work was unmercifully damned, but it was kept on the stage and continually grew in favour until it became one of the most popular comic operas ever written.
These two operas, "Elisabeth" and "Il Barbiere," were not by any means the only ones in which the elder Garcia undertook the tenor rôle at the initial performance, for in the course of the long career which followed he had the honour of creating a number of other parts.
