Music and Visual Arts

I believe music and visual arts have a lot in common and many artistic people have a sensibility for both.
I went to high school in Vienna, Austria, and I still regret the fact, that at a certain age we had to choose between art education and music. I chose visual arts, but would have loved to continue with classes about music as well.
Both art forms can express moods and atmosphere so well, both can evoke emotions in the audience (as can language, I guess, but I never got much into writing).
Recently, when I started teaching a course in color theory, I found myself using a lot of comparisons and referring to technical parallels between the two.
Both art and music benefit from contrast between economy and variety, rhythm and calm, a strong statement and an element of surprise. Accents make the work come alive but the general layout of the composition is more important than the detail.
In any case, I feel it is best not to say it all, but to leave a little room for the pleasure of interpretation.
