TRANSCRIPT

From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of January 12, 2015.

This week, we feature a Blacksburg- and Roanoke-based musical group, with a tune whose name and note patterns recall how rivers and streams follow laws of energy and physics.  Have a listen for about 40 seconds.

MUSIC


You’ve been listening to part of “Minor Meander,” by No Strings Attached, on their 1999 CD, “In the Vinyl Tradition Volume II,” from Enessay Music.  As the tune repeatedly builds up and then cascades down, it captures the pattern of solar energy evaporating water up into the atmosphere, and gravitational energy pulling water back to the landscape, down through stream and river channels, and ultimately to the ocean.  That energy gives water the force to erode and shape a stream’s landscape.  But water’s erosive force—which varies depending on the water’s rate of flow—meets different levels of resistance in the various kinds of rocks, soils, living things, and human structures over which water flows.  Following laws of physics that control how energy changes and materials move, the complicated interaction between stream force and landscape materials results in a variety of stream-channel patterns, which range from single, straight streams to braided rivers with many winding and intersecting channels.  One of the possible patterns is large bends called meanders, seen famously in the Seven Bends area of the North Fork Shenandoah River in Shenandoah County, Va.  Thanks to No Strings Attached for permission to use this week’s music, and let’s end with about 15 more seconds of musical energy from “Minor Meander.”
