Songs should have an infectious melody and rhythm and, I think, should elicit an emotion of happiness or of celebration or of sadness or of sorrow or of love or laughter, whatever.

Any musical form that has been around long enough to have cultural resonance beyond just being a cutting edge kind of communication - but, especially, when it begins to reflect on a time and reflect on a culture - is effective in a musical.

I work in a dramatic context, meaning we write with a lot of character specifics, a lot of story specifics. There's a lot of architecture in our songs.
