Deleuze, Repetition, Rhythm

A primary aim of Difference and Repetition is to distinguish fundamental, dynamic, Repetition from derivative, static, 'repetition'. One way that Deleuze attempts to contrast them is as 'rhythm' vs. 'cadence', respectively, though given the accepted synonymy of those two, this effort is less than clarifying. Another way is his characterizing the static version as 'repetition of the Same', thereby implying that the dynamic version be understood as 'repetition of the Different'. However, this contrast can be interpreted in two, not necessarily consistent ways. On the one hand, 'repetition of the Same' can be interpreted as a relation between two identical terms, i. e. A and A, whereas 'repetition of the Different' requires a minimum of three terms, at least two of which must be distinct, e. g. A and B, and B and C. On the other hand, a 'repetition of the Same' could denote two terms qua identical, with a 'repetition of the Different' accordingly denoting those same terms qua numerically distinct. So, the distinction that Deleuze means to draw is not immediately clear, but what he does successfully make explicit in the relevant passage is his recognition that 'Repetition' and 'Rhythm' are synonymous.
