This is a hip-hop instrumental I created sampling Beethoven's Piano Sonata in F Minor, Op. 57 No. 23, commonly referred to as the Appassionata sonata. I took the sample from the third movement of the sonata, "Allegro ma non troppo - Presto," the very end of that movement.
As you can probably tell, the name of this song is a play on words. Appassionata - A Passion; Not A...
The piano has a very powerful rhythmic pattern which I enhanced with a heavy kick and clap snare and emphasis with a string section.
All of my music production is done in Propellerhead's Reason 5, using an Akai MPK49.
