[TOMT]Classical song starts with an E

I don't remember the tune, so I can't hum it. I found it on Youtube a while back. It starts with an E, I feel like it was a Spanish word or similar for the title. Cannot remember the composer. It's also in 3/4 time and was rather upbeat. Definitely a classical song.

Sorry for the vague descriptions.

Edit: It is an instrumental piece, all one word
