In their playful pursuits, African-American girls demonstrate a fundamental complement of Black music-making: syncopated rhythms and intricate percussion ignite hand-clapping and foot stomping; call-and-response patterns that define the interplay of linguistic and musical doing between their voices and bodies during group play; and a strong ...
Music theory analyzes the pitch, timing, and structure of music. It uses mathematics to study elements of music such as tempo , chord progression , form , and meter . The attempt to structure and communicate new ways of composing and hearing music has led to musical applications of set theory , abstract algebra and number theory .
The Oxford Companion to Music describes three interrelated uses of the term "music theory": The first is the "rudiments", that are needed to understand music notation (key signatures, time signatures, and rhythmic notation); the second is learning scholars' views on music from antiquity to the present; the third is a sub-topic of musicology ...
Media richness theory (Daft & Lengel, 1986) [11] shares some characteristics with social presence theory.

The theory assumes that resolving ambiguity and reducing uncertainty are the main goals of communication.

[1] Communication is defined in both commonsense and specialized ways. Communication theory emphasizes its symbolic and social process aspects as seen from two ...
