Trilla
Rural song coming from Andalucian folk music, which was sung during the threshing in the 'gañanías andaluzas' to the sound of the ringing of the donkey bells. There are those who think that it isn't exclusively Andalucian, although its similarity to the 'toná' (since it doesn't have musical accompaniment either) could contradict this theory. They are wide spread in the area of Jerez and one of its biggest performers was Bernardo el de los Lobitos. Currently Fernando de la Morena includes it frequently in his repertoire.
