Son of a farmer, Rosche attended his first singing school at age 10. When he was 12 years old, his father bought an organ, and George began the study of music in earnest with Miss Christina Carver. At age 15, he attended Dana’s Musical Institute at Warren, Ohio, for a year. He then began teaching piano and organ, and later singing schools. During this time, he also studied harmony and composition with Rev. Corthauer of Massillon, Ohio. At age 19, he went to Stuttgart, Germany, and attended the Royal Conservatory of Music for two years, studying piano, pipe organ, harmony and composition and voice culture. Rosche returned to America in 1876, and went to Indianapolis, Indiana, where he taught piano and other subjects for three years.
