I think I linked to that excellent thread earlier. The idea is not to replace or compete with that or other great threads, but to serve as a resource for new listeners.There is a thread called For Love of Early Music which is a general thread for discussing this long period of music. There are similar threads for each period of music history.
I gather this thread has a specific purpose something like a monthly survey of the entire history of music by considering some works as representing each period as decided by one person.
The music wasn't decided by one person. Yes, I decided which sources to use, but not the works themselves. The works shown in this thread are the result of surveying nearly forty sources of recommendations including classical radio stations in the US, UK and Australia, books by Swafford and others, academic sources, publications from the US and UK, and internet sources such as our own Talk Classical listings.
For clarity, works listed at:
Level 1 received more than 22 recommendations
Level 2 between 16 and 21 recommendations
Level 3 between 10 and 15 recommendations
Level 4 between 7 and 10 recommendations
Level 5 between 4 and 6 recommendations
Level 6 either 2 or 3 recommendations
Level 7 only 1 recommendation
