What is known as the rise and fall in pitch and tone in the voice when conducting close order drill?

The rise and fall in pitch and tone of the voice during close order drill is referred to as inflection. Inflection involves the modulation of voice to convey meaning and emphasis, which is particularly important in a drill context where commands need to be clearly understood and effectively delivered. This modulation helps to capture the attention of the audience or troops and can also indicate the importance or urgency of a command.

In military settings, such as during close order drill, inflection ensures that commands are not only heard but also properly interpreted by those receiving them. This training in vocal delivery fosters discipline, precision, and unity among the squad or unit, contributing to effective communication. The other terms like rhythm, tone, and articulation, while related to aspects of speaking, do not specifically address the dynamic changes in pitch and tone that characterize inflection.
