in bar 1, there is 'sotto voce' written between the right and left hand. what does it mean in this context? does it simply means to play softly or is it asking to play the right hand softly?(since performances oh this piece tend to play the right hand very quietly)
in bar 1, on the right hand, there are accents and slurs on the quavers, is this pattern suppose to be continued on in the successive bars or are you suppose play regular quavers until its indicated again later?
in bar 20 it is marked 'sostento'. what does that mean in this context?
when the crescendo/descendo markings are written below the left hand like in bar 1 and 2, does that mean you are only suppose to change dynamic in the left hand?
With the caveat that in Chopin most all markings are open to the performer's interpretation ...
- Sotto voce applies to the right hand, which should be quiet, as the left hand has the melody.
- The pattern should continue throughout.
- The sostenuto in bars 17 and 21 (in most editions, but also here) means to draw out the deep left hand melody. In effect, it usually means subtly slowing down.
- The crescendo/descrescendo markings below the left hand staff apply only to the left hand. In Chopin they sometime mean "push ahead" or even "speed up" in addition to or instead of growing louder or softer.
