There are MANY melodies and songs (with lyrics) labeled Hora Miresei (bride’s hora). One of the most popular in Romania is a song called Nuneasca (wedding dance, godparent’s dance), which is also the name of a wedding dance. Both songs accompany both dances. Below is sheet music and below that are YouTubes of Hora Miresei & Nuneasca. None of the YouTubes match any of the sheet music!
Below is the 2nd G Hora Miresei, sung by Florica Bradu, that most folk dancers know, described here.
Where there are MANY melodies called Hora Mireasa, Nuneasca seems to have only one. Nuneasca has MANY sets of verses, however.
