Here's how. Hyperscore has three types of windows:

The Melody Window
The Percussion Window
The Sketch Window

Melody and Percussion Windows are color-coded. Take a pen, choose a color and draw in the Sketch Window. When you play your music in the Sketch Window, each line will sound like the music contained in the Melody or Percussion Window with the same color.

Once you have drawn some lines, you can use Hyperscore's powerful harmony function to make your music sound better.

Of course there's a little bit more to it than that, but not too much, and Hyperscore gives you a whole bunch of pre-made melodies and drumbeats to get you started.
