Why is it important for speakers to vary their tone during a speech?

Varying tone during a speech is crucial because it significantly impacts how an audience receives and engages with the material being presented. When speakers modulate their tone, it helps to convey emotions and highlights important points, making the speech more dynamic and relatable. A varied tone can capture attention and maintain interest, preventing the audience from becoming bored or disengaged. This engagement is essential for effective communication, as it enhances the audience's understanding and retention of the information shared. A monotone delivery, on the other hand, can lead to disinterest, causing the audience to lose focus and miss key messages. Thus, varying tone is an effective strategy in oratory that enriches the overall impact of the speech.
