This is my field of "expertise". (What a silly word to describe what I know on the subject. Let's just say that I know more than many, and am supposed to know more than most since I am an artist, and an art instructor.) However, this category is not likely to grow very rapidly since I don't have much to say regarding the subject.
Besides, I have said a great deal about Music in the Abstract Musician.
But who knows. I might surprise myself some day and dwell on this subject. If so, the section is here waiting patiently.
