I finished listening to the
Beethoven early string quartets (opus 18) performed by the Guarneri Quartet.
I enjoyed them, and that enjoyment grew as I became more familiar through multiple listens (which is the way that I usually listen to classical music).
I ended up listening to a lot of other material as part of this "project." I listened to some of the Mozart Quartets, and thought they sounded clearly different from Beethoven (though I would be challenged to describe that difference in words).
I also listened to Beethoven's 1st and 2nd symphonies (which were written around the same time as the early quartets), and I felt like I could tell that this was the same composer. I think the similarity to Beethoven's early symphonies might be the way that the instruments that are not carrying the melody tend to support the restatements of the melody in different ways as each movement develops.
Next up for focused listening are the
middle Beethoven quarters, also by the Guarneri Quartet.
I have listened to the first quartet of Opus 59, and it already seems like these will be noticeably different from the early quartets - so lots more listening in front of me!
