As part of a larger project on using sonification with GIS data, we are experimenting with generating simple melodies from pictures.

Look at the following picture.

We see two rectangles, parallel to the horizontal axis. We generate music by looking at the picture from left to right. We use a higher note (G) to represent the vertical position of the upper rectangle and a lower note (middle C) to represent the vertical position of the lower rectangle. Since a piece of the upper rectangle is always above a piece of the lower rectangle, we generate alternating G and C notes as shown below.

Now look at the following picture. Again we have two rectangles which are parallel to each other, but this time they are at an angle between horizontal and vertical.

We again alternate notes between the top rectangle and the bottom one, but the notes representing the top rectangle steadily rise as do the notes representing the bottom rectangle.

The music generated from this picture is shown below.

Study the following pictures:

Figure A	Figure B	Figure C
Figure D	Figure E	Figure F
Figure G	Figure H	Figure I
Figure J	Figure K	Figure L
