Every week, you will find a new recording here of one Johann Sebastian Bach’s 1080 works, performed by The Netherlands Bach Society and many guest musicians.
Six (6) works posted, only another one thousand and seventy-four (1074) to go. 😉
Music is an area with well known connections to many other domains, people, places, history, literature, religion and many others. Not that other domains lack such connections, but music seems particularly rich in such connections. Which also includes performers, places of performance, reactions to performances, reviews of performances, to say nothing of the instruments and the music itself.
A consequence of this tapestry of connections is that annotating music can draw from almost all known forms of recorded knowledge from an unlimited number of domains and perspectives.
Rather than the clamor of arbitrary links one after the other about a performance or its music, a topic map can support multiple, coherent views of any particular work. Perhaps ranging from the most recent review to the oldest known review of a work. Or exploding one review into historical context. Or exploring the richness of the composition proper.
The advantage of a topic map being that you don’t have to favor one view to the exclusion of another.
