In music, there is tonality and there is rhythm; two elements that work together to communicate emotion. In human discourse, words act as the rhythm while body language is the tonality. Each must work in harmony to evoke communication that is readily understood. Have you ever met someone who gave you a compliment while they were standing with arms crossed and without making eye contact? I bet you felt conflicted because the communication felt insincere, right? But, it sounded somewhat ok. That is because the rhythm of the words and the tonality of the body language were not in alignment.
