Four foundations of effective communication are

Rate of speech:

• Vary your rate of speech to avoid boredom.

• Quick speech shows passion, while slow speech can make simple statements seem profound.

Volume:

• Speak at a confident volume to show authority and belief in what you're saying.

• Many people speak too quietly, missing out on authority, charisma, and confidence.

Pitch:

• Melody can make what you say more memorable.

• Most people use only a couple of notes when they speak, while using a wider range can add melody and impact.

Tonality:

• Emotion lives underneath your words, and your body language and face are the remote control for that emotion.

• The world of theater and singing can inform your use of tonality in speaking.
