Show - Displaying music in jMusic

This tutorial introduces you to one of the jMusic music utilities - ShowScore.
ShowScore displays a score as pseudo notation - half way between a piano roll display and common practice notation.
A score, part, or phrase can be viewed with ShowScore with the command View.show(score) .
The View class is part of the jm.util packagage so classes using the Show utility will need to include the line import jm.util.*;
(This will already be in many classes which require the Write utility for MIDI files.)

When a score is viewed in this way it looks like this:

• Each part has a random colour. Notes in the one part will be displayed with the same colour.
• The intensity of colour indicates the dynamic value of the note. Lighter is louder.
• Chromatic notes are indicated with a sharp '#' symbol just before their onset.
• Each phrase has a retangle around it so you can visualise phrase groupings.
• The ruler bar along the bottom the window is divided into beat increments. Every two beats a taller line is drawn.
• Clicking and dragging on the ruler bar can expand or contract the horizontal scale of the display.
• Beat numbers will appear in the ruler bar every two beats when the horizontal scale allows enough space.
