Piano Sonata in F Major, "Cosmos" - Movement 2 ("Moon")

Uploaded on May 28, 2018

This is the second movement of one of my incomplete piano sonatas. Each movement of the "Cosmos" piano sonata depicts at least one celestial body--there will be movements for the Sun, the Moon, the stars, and the planets.

The twist is that, in each movement, I break an unwritten convention of Classical music (at least from the Classical era). ...OK, I break two unwritten conventions this time. The first convention I break is the time signature--quintuple meter was rarely used (and only started appearing in the Romantic era and in folk music, to my knowledge), and this piece is in 5/4 time. The second convention I break is more important--this piece almost completely avoids common practice period harmony, while Classical music uses that in spades. This piece uses extraordinarily strange chord progressions (F minor-G major-F minor is only the start of it) throughout. Chords mainly move by step-wise motion.

This movement, a ternary-form slow movement, depicts the moon. The music rises and sets slowly, rather like the moon. The alien harmonies are reminiscent of the experience of actually being on the moon--it's weird.

Feel free to crescendo and decrescendo in a Bar 1-like manner every time you see a similarly rising and falling motif.

I finally finished this movement yesterday and tweaked it today. Because of its unorthodox new harmony rules, it's been bothering me for years. Time to finally let go of it...

I was surprised of the structure the beginning to meas. 14 brought! So mysterious and dramatic! Thank you!
As mysterious as the Moon is inscrutable.
