Because instruments were scarce
Explanation:
A minor key usually has a lowered or raised third. Just figure out the chord which is fairly easy. then lower or raise the third or middle note of the chord until it sounds minor. Or you can just play the scale with all the flats or sharps in it. either way.
Well, there are several elements in art including: space, texture, color, form, shape, and of course tone. Lets use space. Space is what gives your photo depth. All pictures should have a foreground, middleground and background. You can use space in your photography by having negative and positive space, allowing the viewer to move their eyes all around the photo.
Hope that Helps!
