Carlos Chávez and I had been friends and composercolleagues for half a century. His role during that period as composer and conductor and his country's chief animator of musical life is now a part of music history.

It is imposible to imagine the Mexican musical scene of the past fifty years without his leadership. He and I felt ourselves brothers-in-arms, desirous of having the musico-artistic life of our two countries join the twentieth century.

His contribution as conductor, teacher and leader of the musico-cultural life of Mexico for half a century will always be remembered. But most of all, Carlos Chávez would wish to be remembered, and rightfully so, as composer. As, I once write: Whatever his musical style, harsh or mellifluos, it is the music of a personality, one of the most striking of our time.
