Binary Tunes

• Use a high note for a 1, and a low note for a 0
• Represent letters using the binary numbers from 00001 to 11010 (1 to 26)
• This is explained in more detail here, with examples: http://csunplugged.org/modems-unplugged-2/
• Steganography: is a message hidden in something else - in this case, a song
• Write your own song that contains a hidden message.

Extension

Consider hiding the binary numbers in the rhythm (long and short notes), or make a video with dance moves that code binary numbers
