Note that we can extend this concept easily by taking more measurements of our sounds. For example we could measure how sharp the onsets of our sounds are. A drum sound will have a very sharp onset, whereas a violin sound will have a smooth onset. We call this measurement the 'attack' of a sound. Now let's consider we add the attack as a third dimension to out picture. The axis with the attack will point into the screen. | Note that we can extend this concept easily by taking more measurements of our sounds.

The more attack we have, the sharper the sound. That implies that drum like sounds would be further into the screen and sound with soft onsets, like a soft bowed violin will be closer to us. Not that adding just this one dimension enables us to discern a much greater variety of sounds now. | |||
