Hora lungă (Cântec lung, Rom., literally 'long song'), is a Romanian regional folksong style characterized by the union of a lyrical text and improvisational melody.
[2] The singing may be accompanied by a combination of the shepherd's flute, a leaf held between the lips and used as a reed, a bagpipe, and non-native instruments.
A variant of the doina, the Hora lungă characteristics are: strong instrumental character, very ornamented, and indeterminate content structure.
Bartók studied evidence of or listened to similar music in central Algeria, Ukraine, and Persia.
Subsequent research has revealed similar music found as far west as Albania and Algeria, and as far east as India, Tibet, western China, and Cambodia.
