Final answer:
A chairperson typically uses one tap of the gavel to call a meeting to order, which is part of the ceremonial aspects of formal proceedings.
Step-by-step explanation:
The chairperson traditionally uses one tap of the gavel to call the meeting room to order. This action has been a long-standing practice signifying the start of formal proceedings. The tap is part of the larger ceremony that involves members being present and gives a sense of gravity to the event. In settings such as the Supreme Court, a gavel may be used to punctuate the beginning of a session, where tradition includes a formal entrance and a chant by the Court's marshal, reinforcing the ceremonial aspect of the gavel's role.
