Although technical discussions are interesting to composers, I suspect that the truly magical and spiritual powers of music arise from deeper levels of our psyche.
I am certain that most composers today would consider today's music to be rich, not to say confusing, in its enormous diversity of styles, technical procedures, and systems of esthetics.
I have observed, too, that the people of the many countries that I have visited are showing an ever increasing interest in the classical and traditional music of their own cultures.
I pick up the New York Times or Time and it's talking about the latest rock group, which I'm sure is exciting to some people, but it neglects a huge area of music.
If we look at music history closely, it is not difficult to isolate certain elements of great potency which were to nourish the art of music for decades, if not centuries.
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.
I must confess, my Spanish is not so good - except I read a little, so I started with the English but then determined that it would have to be in Spanish.
Unquestionably, our contemporary world of music is far richer, in a sense, than earlier periods, due to the historical and geographical extensions of culture to which I have referred.
