I have been induced to write the following pages by the consideration that a brief Memoir of the Philharmonic Society of London, at the close of half-a-century of its existence, may excite interest among the lovers of an art, the advancement of which, not only in England but throughout the civilised world, has during this long period been so greatly promoted by its labours. And this interest, I venture to think, will be felt, in an especial measure, by the numerous body of musicians and amateurs, both in this and other countries, who have been more or less connected with the Society in various capacities; as subscribers to its concerts, as composers and performers whose talents it has called into action, and as members and associates of the Society itself. I cannot but think that a view of its career, obtained even from a narrative so simple and unpretending as mine, may prove instructive as well as pleasing, by showing the means whereby the Philharmonic Society has gained an extent of influence surpassing that of any similar institution, and, notwithstanding the competition of younger rivals, and the vast increase in the number of musical entertainments, has reached its “Jubilee Year” in the enjoyment of “a green old age,” undecayed in vigour, resources, and means of usefulness.
