Have a look here:https://www.serve.com/marbeth/fugues.htmlNow here is a progressive order for learning the WTC (from easiest to most difficult). As with all lists of this kind, variations do exist, and I would love to see some different lists.

The list has been handed down to me through tradition (my teacher received it from her teacher and passed it on to me and so on – I see no reason to disagree so far). I am not familiar with the Bartok edition, but I read somewhere in the forum that it is somehow idiossincratic and definitely not urtext (that is, it is packed with editorial performance directions – which to me says it is a very good edition to find out how Bartok played them, not necessarily a good edition on how Bach should be played, and as with any heavily edited edition certainly not authoritative in any sense). I would be very curious to see if his order of difficulty does indeed tally with the one I posted.Best wishes,Bernhard.
