Tune of the Day: By the Waters of Babylon
This famous setting of Psalm 137 was originally published by English organist Philip Hayes in 1786 as a canon for four voices. It has since been recorded by several artists, most notably by Don McLean in 1971 (the last track in his original American Pie album) and by Sr Janet Mead in 2006. It also made a prominent appearance in the first season of the TV show Mad Men (2007).
Since this is a canon, all four flutes play the same melody, but starting at different times, 4 bars apart. It is also possible to play this piece as a 3-part canon, ignoring the fourth voice; this is actually very common in modern arrangements.
