On Musical Masterpieces

So you, a musically well-educated musician, hear a piece of music new to you, are gobsmacked by it and passionately declare it a masterpiece. Your companion, an equally musically well-educated musician, disagrees. He says it's merely a pleasing, well-made piece of music. Do you imagine you could successfully defend your assessment of the piece as a masterpiece?

If you answered Yes, we suggest you think again and reflect on what the legendary teacher of composition Nadia Boulanger (and we here use the word "legendary" most advisedly) had to say on the matter:

I can distinguish music that is well-made and music that isn't. Yet, what distinguishes well-made music and a masterpiece, that I cannot tell. I won't say that [an objective criterion to distinguish the two] doesn't exist, but I don't know what it is. It all comes down to faith. As I accept God, I accept beauty, I accept emotion. I also accept masterpieces. There are conditions without which masterpieces cannot be achieved, but what defines a masterpiece cannot be pinned down.

Just so.

(The above quote was transcribed from a lovely film on Mademoiselle Boulanger by Bruno Monsaingeon which can be viewed here.)
