intensity element
The amplitude intensity (volume) has an effect on sound texture. For example, a note played softly or loudly has different textures - a drum beat played softly sounds different from one played loudly; a saxophone note played softly or loudly has different textures, and so on. The volume here concerns intrinsic music aspects rather than the overall aspects that would be handled by the volume of a control system (control module).
adsr element
There are different models describing the envelope of a sound. The basic model addresses attack, decay, sustain and release. The adsr element is used to mark the envelope.
Harmonics will be addressed in a future phase.
