I've been writing music since childhood when I put Poe's "Eldorado" and the poems in "The Merry Adventures of Robin Hood" to music.
They say a picture is worth a thousand words, and music can be used to convey more meaning than speech alone, so it is hard to describe music very well.
Most of my music focuses on repeating themes in a fashion that was popular during the Baroque period. A familiar example would be Pachelbel's Canon in D, except that my music is primarily electronic and is mainly oriented toward dance. Still, within it, you will find the repeated phrase that works as a scaffold to hold melodies and counter melodies.
