Campana 6/8 "tata ta ta ta ta tatata ta ta ta ta"
I'm working on this song and probably incorrect or incomplete, improving as i go.
No, no orisha is named, and there are no traits of one particular orisha either (no colours, numbers, attributes, or invocations). There is a religious layer, but it is about egun — the dead and the ancestors — and not about an orisha.
What does point to Santería
What the lyrics are really about In the middle section he tells who he saw "antes de llegar aquí", and that they were "arriba" and "bendiciéndome":
All these musicians have passed away. So they bless him from "above". That makes the song a tribute to the departed greats of Cuban music. In Santería terms this is egun: the ancestors who are honoured first at every ceremony (ibae). That fits the güiro image well: he arrives at the party and the spirits of the great musicians are there.
If you really want to link one orisha to it, Changó is the most obvious. He owns the drums, the dance, and the party, and "llegó la alegría" suits him. That is an interpretation, though; the lyrics themselves don't say so.
