I notice that when writing lyrics, I tend draw much of the emotional content from autobiographical origins. However, when I approach the same song from a sonic angle, I tend to allow the instruments and percussion take a more passive role in terms of conveying that feeling established by the words.
Whether this is a stylistic development of mine, or just inadequacy in my sound design and composition, I don't know. Just a trend I noticed.
What gets you in the mood to create? Is it emotionally driven? Is it just the urge to create? Do you just enjoy making fat ass beats?
