From Hooks & Harmony:
The English composer Frederick Delius said, “Music is an outburst of the soul.” We forget that for some, it’s not as easy as it was for Mozart. Each piece is a work of art, and the composer may labor for days, weeks or months to leave his or her exact thumbprint on it, telling us, “This is me. This is who I am and how I’m feeling.” It’s an extremely personal task, writing music. So many nuances can affect it: tempo, chords, dynamics, melody and harmony, instrumentation and structure. Change one aspect, and you get a different song, or a different feeling.
It’s a good read. Keep going.
