His activities extended in many directions. He founded the Young People’s Concerts at Carnegie Hall, and became supervisor of music in the public schools of New York, completely reforming the teaching of music. The good effects of this are felt to this day. He also founded the People’s Choral Union, in which working men and women were taught singing and the rudiments of music and then promoted into a chorus of twelve hundred voices which studied and performed the old oratorios of Handel and Haydn. He officiated as conductor of the Oratorio Society from 1898 until 1912, and during this period conducted first performances in New York of Edward Elgar’s “The Dream of Gerontius” and “The Apostles,” Anton Dvořák’s “Stabat Mater,” Gabriel Pierné’s “Children’s Crusade,” Johannes Brahms’s “Song of Fate,” and Wolf-Ferrari’s “La Vita Nuova.” His interest in the pedagogy of music culminated in the founding of a music-school—the Institute of Musical Art—which was liberally endowed by James Loeb and others, and which has developed into one of the few great music-schools of this country and Europe. This school soon began to assume such proportions as to demand all of his time and vitality. He therefore retired from other public work, with the exception of the conductorship of the Society of Musical Art, a unique chorus of sixty-five professional singers, giving only two concerts during the season, representing the highest that can be attained in choral singing. For its programmes he drew upon the rich and partly unknown treasures of the _a capella_ choruses of such masters as Palestrina, Orlando di Lasso, Cornelius, and Brahms; and as this chorus was composed of the very elect of New York’s church and concert singers he obtained results ravishing in their beauty. When we were boys together we quarrelled dreadfully and outrageously. Frank would try to assert his two years’ seniority over me and I would resent this with both hands and feet. I remember my mother resolutely separating us and giving me a little room to myself, as that seemed the only way to achieve peace between us. But I am happy to say that since 1885, when Frank returned to New York, we have lived and worked together in absolute harmony and mutual helpfulness. In fact, the unity between us has been so complete that we are now inclined by contrast to consider each other as having been exceptionally devilish and nasty during those early boyhood years. I know, of course, that the blame was entirely his, as he was so overbearing and presuming because of the accident of his earlier birth, while he is equally convinced that I was altogether too cheeky for my age and it was absolutely necessary for my own good and future welfare to put me where I belonged.
