Silence is the language spoken by solitude. There is something awesome and breathtaking about real silence; it is numinous, pulling us out of self-containment and calling us toward the invisible. Spiritual seekers "home in" on silence as homing pigeons to their roost, because therein lies the language for personal communication with the sacred. Silence accompanies us into our innermost selves where we are present to the sacred. When word breaks into that kind of silence, there is communion.
To listen to music or to sing a chant is to do something that has no practical purpose; it is just celebration and praise; it is just tasting the joy and beauty of life, the glory of God. Listening to it, even in the midst of a very purposeful day, reminds us to add the other dimension to our experience, the dimension of meaning, that makes it all worthwhile.
