I find Beethoven's Triple Concerto almost irredeemably bad and would like to understand what I'm missing.

There's something about this concerto I have found impossible to connect with. And I will happily listen to some of the other Beethoven concerto's on repeat (particularly Piano 3 & 4). I find the Mozart and Haydn concertos wonderful and the Triple Concerto is classical-leaning Beethoven (I also happen to enjoy his Symphonies 2 & 4 a lot). This is to say, I do kind of hate it in a bit of a vacuum. Although I think more so than Mozart and Bach, Beethoven wrote some real dross.

I think the Triple Concerto is the most popular piece I would put in the dross category. I think harmonically it's incredibly boring, fair enough it doesn't have any of Mozart's genius sleight of hand harmonic boldness, but the Haydn Cello Concertos, for instance, are not harmonically innovative but they are still a delight. I feel this does almost nothing of interest, and that is accentuated by how plodding it is. The orchestral parts are so simplistic and there's very little rhythmic drive or interest. And I don't even think the three instruments interact with each other in a fun, interesting, whimsical way.

Also it's so long. Almost 20 minutes on the first movement. Approaching 40 minutes in total.

I'm always more interested in the works people don't connect with. And I'm genuinely very open-minded to understanding it, and if anyone wants to share any favourite magical moments from the piece, please do!
