Final answer:
An embouchure is the technique used by wind and brass instrumentalists to control airflow with their mouth and facial muscles, and it is not related to using lipstick or playing string and keyboard instruments. The statement in the question is false.
Step-by-step explanation:
An embouchure refers to the way a musician uses their mouth, lips, facial muscles, and sometimes teeth to play a wind or brass instrument. It involves the adjustment of the player's lips, cheeks, and facial muscles to control the air flow into the instrument, which creates the desired sound. This technique is especially crucial for instruments like the trumpet, flute, clarinet, saxophone, and other similar instruments.
The statement that an embouchure involves using lipstick or is related to playing strings and keyboards is false. Lipstick is not typically a part of the embouchure, and the concept applies specifically to wind and brass instruments, not to strings or keyboards that do not require breath control.
The correct answer to the student's question is B) False.
