Tablature in the context of 'Pulp Fiction' could potentially be a form of coded or symbolic representation, like the way the movie has its own set of symbols and motifs. It could be related to something as simple as the layout of a room which is like a 'tablature' of the events that take place there. But if we consider the more common musical sense, it could be part of the soundtrack's creation or a prop if a character was a musician.
There are many speculations about the man in the iron mask. One theory is that he was an illegitimate son of Louis XIV. He was locked away with an iron mask to hide his identity so as not to cause a scandal or a threat to the king's power.

In the story, the man in the iron mask was a mysterious prisoner. His identity was kept secret, and he was forced to wear an iron mask all the time to conceal his face.
