Synesthetic life:

Made this one around 2007. The original version was tad different but didn't really sound too good. It was less house and more like fast tempo hip-hop.

Blissful choo-choo:

Made this around 2011. Tried a different type of percussion than the usual 1-2, 1-2.

Nature innervates:

Made this one around 2011. Tried something new than usual, mixing in some nature sounds. Sadly, I don't remember what site(s) I took those from.

Waves collide:

Started this one around 2011 along with others in the same file. Basically, I had one percussion looping while I made as many melodies I was inspired to on it. It's how I usually started working with Fruity Loops. Finished this one in 2019 and added an electric guitar part at the end.

Never too much electronic:

Made this around 2008 (I think) and many times it happened that I got bored with one type of electronic genre and headed towards another in the same composition. The trumpet part might be a bit too familiar but I haven't yet pinpointed a song or melody that sounds exactly the same.

It's one of my longest tracks.

Hopping around with the piano synth:

These are some of my first compositions, pretty bare. The first was made around 2008 and the second around 2007, the latter with two friends tagging along on what beats and sounds to put in there.
Since I had no midi controller until 2014, most compositions were done either from mind and drawing notes with the mouse or sometimes playing the notes on Reason's perpendicular keyboard with the mouse, as only Fruity Loops (later FL Studio) had the option to use the PC keyboard at that time. I didn't start these ones on the classical guitar.

It's pretty much my first ever finished composition, made around 2006. It has rock influences (tried mimicking an electric guitar) since I was mostly listening to rock genres from a young age. I also experimented with minors and majors in this one. Overall, quite synth/artificial sounding but I was OK with it back then albeit generally melancholic.
I remember getting some DragonHeart movie (Draco character) vibes when making it, so it's probably the reason it ended up named like that.

As I listened to more types of music more and more and got not only accustomed but inspired, I developed a fancy to recreate my own compositions in various ways. This helped a lot at combining genres. Thus the second and third versions for dragon were born (around 2008). The latter is more of a template than actual music though.

YouTube has removed the second version considering it spam. But the issue was solved the next day after appealing. Good and swift work, thanks. Let's hope it doesn't happen again with the third one :D
