A visit to these rooms is always highly pleasing and instructive, not only to the practical musician, but to all lovers of good music. With the former Mr. Lewis is ready to join in a duet; allowing his visitor to choose from among his many instruments the one with which he is familiar, while he himself is prepared to take any other one necessary in forming the duet. To those who cannot play, or who, perhaps, choose to listen rather than to play, he is ever obliging, and acts as though he considers it a very pleasant duty to entertain his friends. At such times he will commence with his favorite, the piano, and go through successively a performance upon each one of his many instruments, giving his delighted listener a taste, so to speak, of the melodious sweets of each. He delights not only to play, but is also quite fond of conversing on general music; with which subject he is very familiar, and is ever interesting and instructive in discoursing upon the advantages and pleasures to be enjoyed by its study. Indeed, at such times one is in doubt whether to admire him most as a performer or as a theorist; for as the latter he is remarkably proficient, and in treatment delightfully eloquent. As may be inferred from the foregoing, Mr. Lewis is in his manners extremely affable and easy. He charms his visitor by his simplicity, modesty, and freedom from that conceit which might be perhaps expected from one so wonderfully skilled in his profession. Pope's expressive lines apply to but few persons so closely as they do to Mr. Lewis; for he is truly "Of manners gentle, of affections mild; In wit a man, simplicity a child." In these times of charlatanry, when titles are so often assumed with a reckless disregard of truthfulness, I hesitate to apply even to one so fully qualified, so extra skilled in music, as Lewis, the prefix _professor_; for I wish, as I ought, to entirely disassociate him from the mere pretenders to whom, in general, I have just referred. But to him the title surely belongs; and there is no competent judge, who, when made aware of the great talents and acquisitions, theoretical and practical, of Mr. Lewis in the science of music, will not cheerfully accord it to him. Mr. Lewis does not encourage a use of this title as applied to himself: it is, however, habitually given to him by those who enjoy his acquaintance, and who believe that it belongs of right to him. Although depending for his support upon the profession of music, his intense love for the noble art is so pure, is so conscientious, as to lift him far above the exhibition at any time of a spirit of cupidity, and to cause him frequently to discourse the most exquisite music, when he can expect no other reward than the pleasure he feels in thus gratifying his auditors.
