THREE:In 1710 was established the Academy of Ancient Music, the object of which was to promote the study of vocal and instrumental harmony. Drs. Pepusch, Greene, and other celebrated musicians were amongst its founders. They collected a very valuable musical library, and gave annual concerts till 1793, when more fashionable ones attracted the public, and the society was dissolved. In 1741 was established the Madrigal Society, the founder of which was John Immyns, an attorney. It embraced men of the working classes, and held meetings on Wednesday evenings for the singing of madrigals, glees, catches, etc. Immyns sometimes read them a lecture on a musical subject, and the society gradually grew rich. The composers of such pieces at this period were such men as Purcell, Eccles, Playford, Leveridge, Carey, Haydn, Arne, etc. Public gardens became very much the fashion, and in these, at first, oratorios, choruses, and grand musical pieces were performed, but, by degrees, gave way to songs and catches.[157] Vauxhall, originally called Spring Garden, established before the Revolution, became all through this period the fashionable resort of the aristocracy, and to this was added Ranelagh, near Chelsea College, a vast rotunda, to which crowds used to flock from the upper classes on Monday, Wednesday, and Friday evenings, to hear the music and singing. These performances spread greatly the taste for music, and probably excited the alarm of the puritanically religious, for there arose a loud outcry against using music in churches, as something vain and unhallowed. Amongst the best publications on the science of music during this period were Dr. Holder's "Treatise on the Natural Grounds and Principles of Harmony," 1694; Malcolm's "Treatise on Music, Speculative, Practical, and Historical," 1721; Dr. Pepusch's "Treatise on Harmony," 1731; Dr. Smith's "Harmonics; or, the Philosophy of Musical Sounds;" Avison's "Essay on Musical Expression," 1752. Avison also published twenty-six concertos for a band, which were much admired.
