In the summer of 2009, I completed a fifteen-day walk in the western Pyrenees from the French-Basque village of Sare to the Spanish ski resort of Candanchú. The walk formed a topographical contour of ascents and descents, rising overall from near sea level, at Sare, to 1961 metres at Collado de Petraficha. I then plotted this contour onto graph paper and converted it into a sequence of pitches. The pitch sequence, which spans a major seventh from C up to B, provides the melodic material for this piece.
