Within a Region - Dougherty, William 1988- (BabelScores, 2013)
Within a Region Within a Region is a work centered on the harmonic region of a minor third (between B and D). The entirety of the pitch material is derived from a slow oscillation between the spectra of B, C, C#, D, and the microtonal regions between them. This limited harmonic palette is juxtaposed with highly disparate gestural material which first grows out of a single 7th natural harmonic on a C string at the onset of the work. Due to the special tuning (one pianois tuned down a quarter-tone and the hammered dulcimer is tuned down an eighth-tone), notated unisons sound as a blurred pitch region. Various written-out rhythmic devices such as the layering of multiple simultaneous tempi, accelerandi, and ritardandi serve to create a continuous undulation of the perceived tempo
