How difficult is it?
The first movement is slow and technically manageable, but demands even triplets over several minutes. The third movement is another league entirely.
The real hurdle
The triplets have to stay absolutely even for six minutes. That tires the hand more than fast runs do.
How long does it take?
The first movement in four to eight weeks; the third movement belongs in a different category.
A rule of thumb, not a rule – how fast it goes depends on prior experience and practice time. This level is an assessment, not a measurement: most pieces exist in arrangements ranging from heavily simplified to concert level. The rating refers to the common arrangement.
Which instrument suits it?
Lives on quiet, even touch in pianissimo – on instruments with coarse touch response the movement loses its effect.
