Beware though, as "quality" is a tricky concept: for it may be based on objective criteria, but may also be the result of prejudices that often underestimate the quality of new art forms and especially those that attract new generations. Thus we propose an open and fresh approach to arts appreciation. It means to understand the technique of a work of art, because we are talking about artistic disciplines, with specific techniques. A student should be able to distinguish a watercolor from an oil painting, a sonata from a bachata, a sonnet from a free rhyme.
