Cooking really is about process, proportion, texture, color (taste), color (presentation), balance, contrast, seemlingly unrelated items coming together creating new experiences.
It will help you understand these terms in music and art more naturally while at the same time being easier to get started with (i.e. you have the skills necessary to create a dish more than to play the piano and draw)
Oh, thanks. I'm a pretty good cook, or so I've been told, but I'm really into improvisation. Not sure how much of that would carry over to art and music. I have an intuitive sense of flavours that work well together, but I haven't been able to translate that to playing instruments.
