Final answer:
Forward focus or 'placement' of tone refers to the specific positioning of the throat, mouth, and tongue to adjust the fundamental frequency and combination of overtones produced during speech or by musical instruments.
Step-by-step explanation:
In the context of functional resonance problems, forward focus, also known as 'placement' of tone, refers to the specific positioning of the throat, mouth, and tongue to adjust the fundamental frequency and combination of overtones produced during speech or by musical instruments. It involves shaping the cavity formed by the throat and mouth and adjusting the tongue to modify the mix of intensities of the overtones. For example, when a person speaks or plays a musical instrument, their forward focus determines the unique characteristics and tone quality of their voice or instrument. Different positions of the tongue, throat, and mouth create different resonant frequencies and overtones, resulting in distinct sounds. To achieve forward focus or 'placement' of tone, one needs to be aware of the resonance properties of the cavity formed by the throat and mouth and how specific tongue positions can modify those resonant frequencies and overtones.
