In the understanding of this text, the ecology of music encompasses the entire range of what is called “music” in conventional music theory.

The ecology of music concerns the sounding musical event – the music surveyed from outside by the sense of hearing on the level of the mind, and much more even, the musical performance in the concert hall.

So, the ecology of music begins where the composition is already completed, i.e. where the finished musical event resounds on the level of the mind and is perceivable to the inner ear.

The ecology of music also concerns the influence of music on its entire outer surroundings, particularly the musical influence of the mind on its environment.

The ecology of music concerns everything that surrounds the finished piece of music.
And the aspects of the environment of the finished piece of music are: the inner ear of the composer, of the musician, and of the listener, their nervous system, their body, and eventually the whole environment of the musician – the field of material ecology.
