How did Joseph Haydn begin his musical education in Hainburg?

Joseph Haydn began his musical education in Hainburg after his cousin, who served as a school principal and choirmaster in the city, offered to take him into his home to provide him with training.1

While living in Hainburg, the young Haydn sang in the church choir, learned to play various instruments, and gained a solid foundation in musical knowledge. He moved to Hainburg to live with his cousin before he was six years old and remained there until he was eight, at which point he was invited to serve as a chorister at St. Stephen’s Cathedral in Vienna.1
