Those who have always been interested in language are perhaps more likely to have innate musical skills. For the author, it started with rhyming words and phrases, which led to a fascination with rhythm. Barry looks at music primarily bottom-up from the rhythms of language, while others may see it as primarily melodic in nature. But melodies don't exist without rhythms. While prose is not inherently musical, musical ideas can be abstracted from prose as a form of poetry, then winnowed down to something singable or playable as instrumentals. It becomes the "seed" of the music, as classical composers would often do as a building block.
