BigMedley: I just wish there was a part like the coda in
the song. It's so pretty.
pianoluisxD: hey the song its so beatiful you touch it
wonderful but search tha left hand because
its a note wrong!!
JD361001: im playing this song too! it sounds like exactly
like urs! Quit the echo its annoying
NinSiniano: This echo is annoying! Everything else is
very fine!
randomlyunknown2012: i know you are trying to show expression, but
since its a dance i thin the tempo should be
pretty steady. If you are going to have
variations, I think you should make them
slighter.
paopaomanalansan: Oh do you wear eyeglasses?
kafforno: I like it!
chukivano: Much to fast on the notes after the grace notes,
especially on the second page. Keep your playing
at piano on the second page, don't make the
crescendos too loud. Oh and on the fourth
measures of the first two lines, left hand thumb
goes up to D. Lastly, the Coda must be more
dolce, ignore any crescendos your arrangement
may have. and pay attention to the pianissimo on
the second to last measure and the low A, though
it is staccato, should be held slightly
longer, and still pianissimo.
