Since we´ve discussed tutorials and missions, why not step out of design for a bit and enter the sound department? More specifically, let´s talk in-game music:
The game I´m working one won´t have space for several tunes. In fact, we might have only one tune for the opening and another one (probably a variation) for the game itself.
Yes, only one. A short one. That´s not much, I know. So how do we make it suitable for the game?
My personal experience is that repetitive melodies get listeners tired pretty quickly. That´s probably more true with casual games. That´s why I am considering to use only percussive sounds in the soundtrack.
First, it would fit the game style. Secondly, it´s very economical. Finally, I believe this kind of music can be more easy on the ears and last long, since listeners tend to create the other music elements in their head while listening.
Am I forgetting something? Is there anything wrong with this line of thought?
