However, some of the key early performances at the Tonkünstler Society in Vienna were for much larger forces (as was the fashion at the time); Haydn led performances for both large and small ensembles. Material surviving from these large-scale Viennese performances indicates the use of tripled wind (arranged into three separate groups, each one similar to the "Harmonie" wind ensembles of the time), doubled brass and as many as ten horn players, backed up by at least eighty string players and similar numbers of singers.
