Petersen #4643315. Published by Lynn L. Petersen (A0.973237). Interplay (2011) is a duet for flute and tenor saxophone in three movements.  It was inspired by a trip to Glacier National Park in 2010.  Its three movements are musical depictions of scenes and formations in the park.  Rapid Ascent features ascending arpeggio figures, inspired by sheer cliffs and steep elevations.  The lakes and streams in the park are the basis for Rippling Current, which features gentle undulations and subtly changing patterns, reminiscent of kayakers gently paddling across a mountain lake.  Jagged Edges suggests the sharply irregular rocky ridgelines through disjunct melodic lines, staccato, and shifting meters.
