A scalable quality of the material.


Parameter is a type of Aspect that allows you to change a musical quality in some "direction" by an arbitrary small value.

Natural parameters include volume (this might be also a dimension) and tempo (not a dimension).

Parameter's give unique opportunities in music game design. One of them is a possibility of translating spatial relations to music.

By contrast one of the most non-parametrical example of an Aspect would be genre. Genre is usually changed directly from one to another. Even if you can make your madrigal gradually more and more jazzy, the "direction" of the transition and the choice of two edge values on that "madrigal-jazz scale" is subjective beyond common agreeability.
