Tolkien's use of song and verse are an integral part of his writings. I am not musically talented myself, nor am I a scholar of song structure but I appreciate how he uses them for plot exposition and character development. In The Lord of the Rings, the medium of song is also used as a means of conveying the enormity of Middle Earth and the wealth of history therein. They give us a sense of the realms lore and heritage, stretching back over millennia. The respective sophistication of each song also reflects the culture that created them. Songs from The Shire are rustic and quaint. The songs of Men are bombastic and bold. Whereas Elven music is often melancholy and complex.
