"Music uniquely among the arts is both completely abstract and profoundly emotional. It has no power to represent anything particular or external, but it has a unique power to express inner states or feelings. Music can pierce the heart directly. It needs no mediation. One does not have to know anything about Dido and Aeneas to be moved by her lament for him. [Henry Purcell's opera, from 1689] Everyone who has ever lost someone knows what Dido is expressing. And there is, finally, a deep and mysterious paradox here, for while such music makes one experience pain and grief more intensely, it brings solace and consolation at the same time".
