Australian pianist Simon Tedeschi had this to say about comparisons in a recent article (reference & link below). Its part of an article about the types of questions that audience members inevitably ask him after a rectial.
[One question is 'Who is your favourite composer?']
Why are humans so addicted to comparisons? Why must there be a best? This is like asking me what my mood is like on Thursdays at 5.23pm. The sum total of keyboard literature is enough to satisfy even the most prolific of pianists, such that we will never master it in ten lifetimes. As I have said before, the music will always be greater than us. Aside from this cornucopia, there is the simple matter of mood. One day I may feel angry and so will gravitate towards Beethoven's seamier works. Before bed, my old friend dopamine will ensure that a Bill Evans ballad does what the doctor ordered. Bach, I feel, is the 'greatest' composer that ever lived, and yet his music is perhaps not my 'personal favourite.' These are the kind of variables that pillage my brain after being asked this well-meaning but futile question. I call it hiatus interruptus - the unwillingness to grant a performer a break from all mental activity after a huge night. . .
[Another question is 'What do you like more, jazz or classical?']
I would give classical 9.7 out of 10, but jazz only 8.2. [this 'statistical' answer is obviously a joke, but Mr. Tedeschi plays not only classical but also jazz music]
I mean this quote as a stimulus to discussion and debate.
So just seeking your opinion on the issue of making comparisons about music. An open discussion about that.
You can discuss comparisons you find useful and those that you don't. You can give examples.
