Musicality in dance is the quality that separates the babies from the ballerinas.  According to Nichelle Strzepek of Dance Advantage,  musicality in dance has two main components. Receptivity and Creativity.

Musical receptivity is ones ability to receive, comprehend, be sensitive to, and have a working knowledge of musical concepts like rhythm, tempo, phrasing, and even mood.

Musical creativity (or musical artistry) is the ability to connect with accompanying music, interpret it, or phrase and add movement dynamics that relate to music even in the absence of accompaniment, in a way that is unique or interesting (read her entire post on Musicality in Dance:  What is it? Can it be taught?)

In this video gone viral,  twin babies exhibit musical receptivity and creativity when their father plays a tune for them on his guitar.   Most enjoyable for me is the way they connected and interacted with the music, each other and their parents.   Baby ballerinas in training!

Inspiration from 11-month olds: priceless.
