romatic period嘅小提琴作品!(急)

I would recommend Zigeunerweisen by Sarasate.
( Whole name: Zigeunerweisen ( Gypsy Airs) , Op.20 ) ( 流浪者之歌)

It is a very famous and well-known piece,
also the most famous piece of Sarasate.
Many people can recognize it when listening.
It is quite technical-demanding too, ( a lot more than grade 8 level)
and it is very romantic.

You may go to the following website to look at the scores.

Salut d'Amour by E.Elgar.
(very romantic piece)
