Aspect

Any quality of musical material.

Usage

Event — "Anything" in music terms — a unit of music at any given scale of consideration.

Just as an event is a very broad term for "what may happen", aspect is able to equally broadly describe what is being played. Similarly, like with events, you can have macro-, mezo- and micro- aspects.

Dimension — A scalable quality of the material.

Parameter — An aspect applicable to a single sound and continous.

There are some distinct types of aspects. Check for example additional info on dimensions and parameters. Yes/no questions that you ask about an event relate to binary aspects. Some aspects are formal in character and some deal with wider cultural references.

Not every aspect can be applicable to every type of musical material, and the complete list of aspects is impossible to make. Here are some examples:

Aspect Remarks
Density mezo-
Duration the only (?) aspect applicable to every material, as long as precison is not required
Composer for pre-composed material
Genre macro-
Mode if material uses modes
Mood mezo-
Number of sources expressed in natural numbers
Pitch micro-, parameter, dimension
Stability quite subjective and imprecise measure
Style macro-
Tempo dimension
Timbre complex micro-aspect, parameter
Type of sources constellation or family of instruments
Volume parameter, dimension

Theoretical clarification (!)

The great overview of the topic can be found in Carl Bergstrøm-Nielsen's "Sound is Multi-Dimensional"
https://vbn.aau.dk/files/66106441/SIMD.pdf

In the treatise and historically, Dimensions/Parameters/Aspects are not separately defined, and there are many takes on this topic. Parameter is often a basic term, and Aspect here at G4M is equivalent to the most broad understanding of a parameter (parameter is as in a narrow definition). The distinction between different types of aspects is introduced in the context of music games design due to more formal (mathematical / systemic) nature of complex games.
