Work with the two choruses which sang in German and in Latin began in October, 1915. Hitherto the orchestra had had no chorus of its own, but was obliged to depend on the good will of Philadelphia choral organizations to co-operate in producing choral works. Now for the first time the name “Philadelphia Orchestra Chorus” appeared, and, as the first chorus of 400 members, was trained by Mr. Stokowski. The second chorus of 400 voices was rehearsed by Mr. Henry Gordon Thunder. The requirements were severe as to personnel and rehearsals. The spring was occupied in the selection of voices. When rehearsals began in October, men and women were rehearsed separately until January. After that they had weekly rehearsals together. Singers who were inattentive or who skipped rehearsals were not retained, and towards the end everybody was over-worked and wrought up to a pitch of excitement.
