"Somewhere between the vast distance that separates the mind from the heart lies a source of constant conflict and question that we refer to as moods. Unlike feelings, moods change with the mere suggestion of change. Unlike attitudes, moods cop their own behavior. Joy is an example of a feeling. Happiness? It is an attitude. But Ecstasy is a Mood! Then there is Depression... another feeling. Sadness? Once again, an attitude. But Desparation is a Mood! Music has a powerful effect on our moods."
