What surviving tunes are the oldest, and how old are they. I presume most of the oldest will be early church music. The oldest, English, tune or song I can think of is Summer Is A Coming In which I think is about 750 years old. What others are still out there? Which is the oldest? How far back in time can we reasonably push the date for the oldest tune? Are there Jewish, Hindu, Buddist or other religious songs/tunes/chant that have survived for millenia?
