Musicality is a noun that means sensitivity to, knowledge of, or talent for music. The word also refers to the quality or state of being musical (aka melodiousness.) A musical person has the ability to perceive differences in pitch, rhythm and harmonies. One usually differentiates between two types of musicality: To be able to perceive music (musical receptivity) and to be able to reproduce music as well as creating music (musical creativity).
Musicality may also refer to fitting a dance to the music being played, with the goal of relating the dance to the music's rhythm, melody, and mood. Good choreography is always musical. Beginner dancers usually think they should step on the beats of the music, and may vary the size of their movements with the volume of the music, while more advanced dancers dance to the melody, variations of rhythm, and mood. This is the key characteristic of improvised dancing. Unlike most ballroom dances, which tend to use the music as a metronome to guide the dance, Lindy Hop, West Coast swing, Argentine Tango, for example, view matching your dancing to the spirit and mood of the music as the highest goal achievable.
