I compose by trying to capture the emotions of the moment. It might begin with a motif, a short phrase, an idea, a feeling, or an interesting chord change that suggests a mood striking my inner gut deep emotions. The melody or chords open up a deep inner feeling or perhaps a buried memory or maybe even a hope or desire.
A Memo is a note, a memory, a moment of communication. A reminder to anyone who will listen to take a fresh look.
