Claro de Luna is an Argentine tango-style adaptation of the well-known first movement of Ludwig van Beethoven’s piano sonata no. 14 in C# minor, “Quasi una fantasia”, Op. 27, no. 2, popularly known as the Moonlight Sonata. Dark, bold, and passionate, this adaptation remains true to the original’s harmony, melody, and form. Its edge and driving energy derive from Argentine tango’s characteristic rhythms and sharply accented beats.
