As a witness for Peace, our role was to witness in two senses of the word: we SAW, and by our presence we offered affirmation by word or example of a solidarity based on love and faith and the Good News. The word that is much used is "accompaniment." Our contribution was less in our doing than our being-with.
It is not difficult to understand why music often touches us so deeply. Music is the key to the power within -- a bridge of sorts -- and there is an infinite variety of music suitable to individual tastes and preferences to lead in this inward search. Composers are often aware of the power of the music that comes from within them and have from time to time spoken of it ... Brahms, being deeply aware of the source of his creative gift, stated that his creative power was released in the moment of his realization of his oneness with the Creator.
