To me, the pop music feel "predictable", even more like regurgitation of previously thoroughly chewed meals for optimal mass digestion...
Yes, to me too. The difficulty here is the use of the term “predictable” which to a large degree can be exchanged with the term “expectation”, EG. It’s predictable if it does/goes how we expect. But then that gets complex because the history of classical music is largely about what we “expect”; melodies and harmonies create dissonances, progress/lead into each other and “resolve” into consonances in line with rules developed over centuries based on what sounds right/is “expected” . In the mid romantic period and later, holding that “expectation” before “resolving” it is one of the defining traits. In other words, “predictability” isn’t necessarily the issue (“boring”), it’s more about the details of how we (composers) deal with predictability. Ravel’s Bolero should be one of the most boring pieces of classical music ever written but it’s a firm favourite of classical audiences.
P. S. I feel that the tragedy of Haydn is that his output is massive and quite even, and he did not left prominent masterpieces like many other composers.
Not sure that’s entirely true. There’s the “London Symphonies”, “The Creation”, the “Tost” quartets and the Trumpet Concerto. In a sense though, Hayden’s great genius is also his own downfall. If you pioneer a musical form (the symphony) that is so appreciated, respected, popular and long lived, it’s inevitable that other geniuses will come along, develop it further and that you’ll eventually be superseded.
I’m guessing predictable for a trained musician might be fairly different from predictable to me.
That’s not necessarily true or rather, predictability is not necessarily a bad thing. I’ve known a number of classical musicians who would list Mozart as their favourite composer. On the other hand, actually getting inside a piece (when you practice and perform it) and analysing the score in detail definitely gives you a perspective that is likely to be significantly different to an average member of the audience. Although again, that doesn’t necessarily mean you’ll like it less. In addition, a musician is almost certainly going to be biased by the instrument they play. An orchestral trumpet player is most likely to be biased towards those pieces which have particularly good (and enjoyable to play) trumpet parts but also, after 80 rehearsals and 20 performances of say Mozart’s Symphony 40, it can get a bit boring for some, especially as it’s not very technically demanding for many of the musicians compared to today’s standards. Additionally, I can (or could) usually stop at a particular point in a Mozart score and ask “what would be the perfect chord/chord progression or orchestration to use next” and almost invariably, my answer to that question is exactly what Mozart actually did. Of course, I’m no Mozart, I just have the benefit of knowing the “rules” from 200+ years of Mozart being extensively studied and analysed, “rules” that Mozart knew instinctively and was at least partially responsible for establishing as “rules”, an entirely different scenario.
In the era where most performances are played back as recordings, the goal is to create the "one and true" performance... straight, idiomatic and without any reinterpretation by the performer.
That’s not really true. It’s certainly true that recordings provide a historic, repeatable record of definitive performances/interpretations, which cannot help but influence and potentially limit other performers’ interpretations. Additionally, due to the ability to edit takes, there is an audience expectation of a level of technical excellence not expected before the age or recordings, which can also influence the levels of risk performers’ are willing to take. However, these are both just somewhat limiting factors, NOT factors which completely eliminate reinterpretation or taking performance risks. Indeed, taking risks and individual interpretation is still what separates the “great” performers/conductors from the “good”, albeit within a somewhat tighter framework than was the case before and in the early years of the recording era.
