Tune of the Day: Lamentabile by W.F. Bach
This is the second movement of Wilhelm Friedemann Bach's Flute Duet in F major. It is an extremely slow and meditative piece, marked “Lamentabile”, which in Italian would literally mean “mournful”. The movement is set in binary (AABB) form, and the first part starts out as a canon at the fifth; that is, when the first voice enters it repeats the melody exposed by the second voice, but a fifth higher.
Thanks to Jean-Marc for suggesting this piece!
