The primary focus of "pitch" in vocal expression is indeed the highness or lowness of the voice. Pitch refers to the perceived frequency of a sound, which means it determines whether a note or sound is considered high (like the sound of a whistle) or low (like the sound of a bass drum).

In vocal expression, pitch plays a crucial role in conveying emotions, attitudes, and intention. For example, a higher pitch can express excitement or nervousness, while a lower pitch may convey seriousness or calmness. Therefore, understanding and manipulating pitch is essential for effective communication in singing, acting, or public speaking, as it can significantly influence how a message is received by an audience.

Other aspects of vocal expression, such as volume, quality, and rate of speech, are important as well, but they do not define pitch itself. Volume relates to how loud or soft the voice is; quality refers to the particular timbre or texture of the sound; and rate of speech indicates how fast or slow someone is speaking. These elements contribute to vocal expression but are distinctly separate from the concept of pitch.
