Garry Garrett's Homepage All artforms have rules. Painting, singing, dancing, figure skating, computer programming, writing, etc. all have rules, some defined and some undefined. The amature does not understand the rules, and produces low quality art. Good artists learn the rules and follow them. Great artists learn the rules so well, that they learn when, where, and how they can get away with breaking the rules. Occasionally, an amature who does not understand the rules will break them in just the right way as to produce a great work of art. Because they do not understand what they have done, they will never again produce a great work of art. In music this is known as a "one hit wonder", but it occurs in all forms of art.
Breaking the rules often involves leaving out some "necessary" item, necessary because it's dictated by "the rules" of the artform. Rap music is music without harmony. Modern art is art without defined form. In the example of Rap music, Great artists, while they do not use harmony, they understand it and their music is written with harmony in mind; there's an implied harmony that's missing from the piece, which your mind fills in (the mind is good a filling in missing bits of information). The amature Rap singer does not understand harmony and the missing/implied harmon does not harmonize and the music sounds bad to the decerning ear. It is a falicy, particularly in the world of painting and sculpture, that a school can produce "modern artists". Modern Artists worth their salt have tons of classical art pieces to their credit that they have done that has tought them the rules. They know why that are leaving out what they are leaving out. They have an idea what their piece would look like done in the classical style and they know why they are not doing it that way.
Too many people put down modern artforms, because too many people who don't understand them attempt to create them. Because of the high paise (and $) that they earn, everyone wants to skip the classical and go right to the modern.
That's my $.02 worth.
