scale

scale - noun - a collection of musical notes that provides material for part or all of a musical work.

Someone once said the most difficult thing to define is the simplest. How true of the musical scale. Not only is this a collection of notes, but it also has several properties and additional (adverbs!) to describe it (diatonic, chromatic, whole-tone, etc). Ignoring most of these additional properties doesn't really do justice to the term, but consider the following items: scales go up and/or down a musical score and the separation of the notes from each other is constant. If you'd really like to be bamboozled by the description of a scale, try out wikipedia.

Post-Impressionism

Post-Impressionism – n - A varied development of Impressionism by a group of painters chiefly between 1880 and 1900 stressing formal structure, as with Cézanne and Seurat, or the expressive possibilities of form and color, as with Van Gogh and Gauguin.

The best known post-impressionist is Vincent Van Gogh (1853-1890). His Starry Night is a spectacular example.

In my opinion, the post-impressionists were the beginning of the end for Western art.
