In Music each note is defined by its environment. There are no good or bad sounds – there are only sounds within a certain harmonic neighborhood of more or less tension.
It’s the individual human ear saying: “This tune is beautiful.” or “This sounds horrible.”
And each individual pair of ears is part of a certain cultural harmony itself, is part of a cultural environment.
Each human being is able to enlarge her or his cultural environment. Each human being is able to be part of a more complex harmony than the one she or he was born into. It takes the virtues of openness, curiosity and tolerance – but the rewards are huge.

What would this environment of stones be without the colourful leaf?
What would the leaf be in an environment full of other gaudy leaves?
