This study will provide systematic and concise review of nonverbal communication highlighting mimicry and gesture codes as its two areas of research. Nonverbal communication is a way of communication in which, instead of using words, use of nonverbal cues can reveal much more to the communication partner. The goal of this study is aimed toward research of nonverbal communication as one of the communication areas which is frequently secondary in communication research. That is completely wrong approach as it is scientifically proven that people communicate 7% verbally (content of the message), 38% by voice (way of speaking, accentuation of the important parts, syntactic order, pauses and differences in rhythm of the speech) and 55% by proxemics and kinesics (facial expression, physical touching, spatial distance from communication partner, directing and gazing etc.) (Zrilić, 2010). This study starts by definition of communication and systematic division of communication on different areas, followed by introduction in visual values of spoken language: muscle movements which are named mimicry, also arms, hands, shoulders and body movements which are named gestures. Theoretic findings which display origins of nonverbal codes clearly point out that the nonverbal code has developed much earlier than the spoken code. People had used exclusively nonverbal signs in early stages of communication, language has developed afterwards. All suggested findings support alignment of mimicry and gestures as prosodic means despite of, according to the definition of prosodic means, not being included in the speech layer.
