I don't know if the umbrella (or parasol) has any relation to the music (I guess the musical group is folkloric in nature) or is there by chance. If it were one thing or another, perhaps they would say that it is music to summon the rain or to alleviate the sun. But, in any case, the object plays well with the red touches of the clothes of the members of the group, and, in addition, the scene stands out in a particular way.
