Individuals commonly move their bodies freely while listening to music. In recent years, many researchers have investigated the relationship between music and physical movements. Contemporary dancers move freely during improvised performances. Contemporary dancers move based on their own physical intuition. The dancer’s physical intuition is influenced by the surrounding environment including music. In this study, we conducted observation and interviews focusing on the selection of music during a warm-up period among contemporary dancers. The music selected by contemporary dancers during warm-up was divided into two functional roles. First, some dancers preferred music that enabled the dancer to concentrate on their own physical movement. In mental training for athletes, concentrating on music is commonly practiced to increase general concentration. Second, some dancers preferred music that directly affected physical movement. In this case, the dancer perceived and was sensitive to the music, and reflected it in their physical movement. The ability to perceive and sense music is considered to constitute musical literacy. In addition, musical literacy also includes the sense of pitch, sense of tone, adjustment, rhythm, and listening ability, forming the basis of various types of music-related activities. Dancers acquire musical literacy through dance.
