Question for classical-enclined editors: I was reading about 20th century classical music and realized we have a way to store information about tonal music (i.e. the main key used in the work) but not for atonal (or serial or dodecaphonic or…).
Should we? And how would we display it? I thought about adding this option in the Works Key attribute but it doesn’t look like a clean solution (“atonal” or “serial” or “A major” or “A minor” or…).
