I'll give you a different example. Chopin - Waltz in C Sharp Minor...states Tempo Guisto which is perfect time yet all the professional recordings i have heard have a rubato time to it not perfect time.
Explain Please.
those who are experts of chopin know considerably well how to play his compositions in the style they are written. would a waltz marked with tempo guisto on it be interpreted differently with a tempo guisto polonaise? i would guess so. at least i would expect subtle rhythmic difference in how a pianist approaches the two pieces.
some thoughts:
1. does tempo guisto in waltz mean that one has to play the piece at swiss clock precision? i very much doubt it
2. could it mean "perfect tempo of a waltz ", or "perfect waltz tempo?",
3. or is it possible that chopin was hitting on a relatively stricter time, due to the then fashion of certain type of rubato, by which chopin didn't want it in this particular piece?, which therefore can be translated into something like: "ok, guys, now play this
waltz in stricter waltz rhythm, will you?"
i can see myself buying no. 2 or 3. i doubt he wrote tempo guisto at the beginning of the piece, while talking loudly to his students "ok, guys, here is a metronome. play it just like it!!".
