Dramatic music depends more on colour than on form, Classical music more on form than colour: but both reach to the expression of the highest extreme of emotion. Lyrical music uses both colour and form, but keeps more in the middle range of emotion. Ecclesiastical music possesses forms of its own, and traverses a narrow field of immensely powerful emotion while it uses little colour, or rather it combines every colour used, with one strongly prevailing tint. It is at once.
