Chopin uses the term stretto on places that doesn't always "fit".
Could you give an example?
One place in the concerto, and one in nocturne op 32/
There's one in op 10/12
Where in which concerto? As for the nocturne, the slight speeding up in the stretto makes perfect sense to me.Yes, some people slow down there. They shouldn't: the stretto version is more exciting.
