[6] Rossini's desperate idleness and habits of procrastination are proverbial. On more than one occasion personal restraint was resorted to, to compel the fulfilment of his engagements. Thus, at Milan, sentinels were placed at his door, and no exit allowed him, until he had completed an opera of which the two first acts were already in rehearsal. Barbaja, the celebrated _impresario_, kept him for some time prisoner in his palace on the Naples Toledo, refusing him liberty until he should have composed the long-promised opera of Otello. Remonstrances were disregarded by the inflexible manager, so Rossini set to work, and, with his usual facility, soon sent down a portion of the score, headed _Introduzione_. This was transmitted to the copyist; but the same evening Rossini applied for it again, on pretext of alteration. Next morning another MS. reached Barbaja, inscribed _Caratina_. It followed its predecessor to the copyist, and, in like manner, was re-demanded for correction. Barbaja gleefully rubbed his hands at finding that these revisions did not delay Rossini, who sent down page after page of copy, to the extent of an entire act. But the irritable manager was like to go distracted when, on applying to the copyist for the whole score, he found the introduction was all that had been composed. It had been travelling to and fro between Rossini and the theatre, and, at each journey, the incorrigible composer had headed it with a different title. The trait is characteristic, and strictly authentic. The same story is told, at greater length, and with some embellishments, in one of Alexander Dumas' volumes of Italian travelling sketches. Managers, however, found compensation in Rossini's rapidity for his provoking idleness. When he did set to work, he got over the paper at a gallop; and, when driven to the last minute, his fertility and invention were wonderful. Some of his finest things were composed on the spur of the moment, and in breathless haste. The celebrated air _Di tanti Palpiti_ is one of these. His dinner hour was at hand, when, driven to the wall by urgent solicitations, he one day sat down to compose it. His cook, learning that the _Maestro_ was really about to work--no very common occurrence--thrust his head in at the door, and ventured a supposition that he had "better not put the rice to boil." "On the contrary, boil it directly," replied Rossini, who was hungry. Before the rice, that indispensable preface to an Italian dinner, was fit for table, the air and its introduction were composed. _Di tanti Palpiti_ is still familiarly known as the _Aria dei rizzi_.
