i recently came accross to pancada and his tattoos and i really like this one

unfortunetly i didnt find any meaning yet or any more info about this tattoo and what it means. The closest thing ive came across was that this is some sort of musical note which i loved the idea.
id be grateful for any information

not from brazil but, unless I am mistaken that looks like a view of stairs from behind a keyhole no?

its basic that, thats nothing special from this tattoo
