Follow Through - String Ensemble

I noticed a certain format by which a lot of music follows. I don't really know what it's called, but it's where one instrument plays a motif over and over again, and instead of changing the motif, the composer will just add more instruments with different instruments to show the progression of the song (and change the motif when they feel it's appropriate ofc). The songs I saw do this that inspired me are "Eye of The Gate Lord" and "Charge! Fearless Warriors".

After listening to "Charge! Fearless Warriors" I decided to try my hand at that style of music, and I gotta say, I loooove composing this way. This is just a short song to show you what I'm talking about, but I'm probably going to make this into a fully orchestral piece.

Anyways, Enjoy! :)
