Angor hoped to make something crystal clear, so he spent some time selecting materials with proper colors.
Next, he needed to choose a piece of music as well as an illusion that went with the music.
He already had something in mind; he would use "City of Sky".
Now the question was, what kind of scenery suited the music best? Different people might have different views about this one since they all had different tastes. Angor did not expect to find a perfect answer. However, the least he could do was to try and find something commonly accepted.
He would go for something that was "relatively perfect" to accompany the City of Sky. Something that most people would find acceptable.
And he would do so by listening to the music carefully just like how people comprehended books by reading them a lot.
He opened the music folder and played the song.
