Yes, I have been a composer before knowing MLP.

And even if some of my works have a relation to MLP, they're only a part of my creations.

I started to "compose" when I was eight years old. ("Compose means: I figured out what sounded good and what sounded bad. My first real pieces of music were created about five years later.)

One of my earliest works was a "concertino" in G minor for organ, whic means a piece in four parts (prelude - fugue - interlude - fugue). I composed it during summer vacation 2008. The sound is MIDI-based (and terrible, I know that^^)

One year later, again during summer vacation, a second piece of music for organ was created. This time it "only" was a Prelude and Fugue combination, C major. (My music professor said the ending was funny^^)

Somewhen in 2010 a friend of mine asked me to compose a short piece of music for piano for him to play, and I ended up with a fugue in B minor:

Time passed by, and around February 2011 I started a little experiment. I composed a fugue with a theme an other composer already had used, and my choice was Bach's Fugue in A flat major from the "Well-Tempered Clavier Book". Instead of piano I composed for organ. But listen for yourself:

November 2011: I found the beginning of a fugue I had started about a year before and decided to finish it. Piano, E flat major.

If you like these pieces of music, let me know it. If you don't, let me know it as well.^^

Very well done. They're all very pretty. I'm not usually much into piano, as I tend to prefer fully orchestrated pieces, but these were great!
