Character : Of an ambivalant nature, loquacious and mumbling, timid and craven, he will sometimes play the old man, sometimes the servant, but he will always play a secondary part. He will thus play the part not of the Doctor but of his assistant or apothecary, not of the Judge but of his magistrate, not of the Notary but his clerk. He may also be a family man but will be of less importance than Pantalone.
His main trait is his endless stutter. When he tries to convey his thoughts, the other more alert characters will finish his words or sentences for him and he ends up uttering a completely different concept than he had originally planned. This annoys him to the point of anger and bad humor which he will reveal to the audience in long diatribes.
His problem in asserting himself and assuming his rightful place also stems from his blatant clumsiness. For exemple, if he is the Notary clerk, he will inevitably drop rows of documents and will spend the whole scene trying to retrieve them.
Tartaglia is also dreadfully myopic which prevents him from enjoying due success and therefore leting all the good deals pass him by.
Costume and Mask : He is dressed in a green and yellow stripped suit, with a large felt hat and boots that are way too large for him. His mask makes him look thin and gaunt.
He will occasionally wear thick, heavy glasses.
