The effect of a music/ movement program on preschooler's motor rhythmic abilityIntroduction rhythm is present in any human activity (Oreb & Kilibarda, 1996) affecting not only the music performance but also the performance in maths, language and academic achievement (Kuhlman & Schweinhart, 1999), that is a wide framework of human cognition and behavior. Moreover, rhythm is believed to influence the development, performance and learning of motor skills (Thomas & Moon, 1976). However, in spite of its significance in human's life there seems to be no consensus for the exact meaning of the multifaceted rhythmic phenomenon.
