Three different forms, but their common feature is their rhythm which, depending on the speed and the manner in which it is performed, will tell us whether we are dealing with a tango, a tanguillo or a rumba. The similarity between them could lead to confusion, and this is the reason for which the three styles are collected in the same CD, so that the differences between them may be appreciated clearly. Each rhythm lasts for roundabout 10 minutes, one version with a guitar, and the other without. Singing: José Parrondo. Guitar: José Manuel Roldán. Hand clapping: Manuel Salado and Juan Reina. Cajón (box-drum): Manuel Salado.
