Perhaps two million years ago the creatures of a planet in some remote galaxy faced a musical crisis similar to that which we earthly composers face today.
Perhaps many of the perplexing problems of the new music could be put into a new light if we were to reintroduce the ancient idea of music being a reflection of nature.
In a broader sense, the rhythms of nature, large and small - the sounds of wind and water, the sounds of birds and insects - must inevitably find their analogues in music.
One very important aspect of our contemporary musical culture - some might say the supremely important aspect - is its extension in the historical and geographical senses to a degree unknown in the past.
The retrospective glance is a relatively easy gesture for us to make.
