An expanding triangular series for an integer n is 1, 2, ... , n-1, n, and a contracting triangular series for an integer n is the retrograde of the expanding triangular series for n.
By setting 1 to a unit of time, either series can be realized as a rhythm in which the rhythm's ordered series of inter-onset intervals is an expanding or contracting triangular series, measured according to this unit.
I can think of isolated examples of such a rhythmic series. But I'm wondering if there is a composer or type of music for whom/which this sort of thing is a distinctive aspect, assuming n of sufficient size (and variety) to be distinctive.
