Paraverbal Communication Skills

Paraverbal communication refers to the messages that we transmit through the tone, pitch, and pacing of our voices. It is how we say something, not what we say.
The pitch is your key voice and is it high or low. So the high pitch in most times will interpreted as anxious or upset, while the low pitch will be more serious and authoritative. Note that the combination of various pitches to create a mood.
