Method One: We could take each note on a keyboard and assign it a letter,
in
fact, that is exactly what the MIDI
standard does. It has 128 different notes.
Middle C is 60, C# is 70, D is 71... This allows us to "play" the small primes by
just playing the corresponding notes. You can hear this by clicking on the ear on
the left (or use the eye to view the score).


The problem with this approach is that it only allows us to play a few primes
(at most those below 128) and sound cards (as well as human ears) have difficulty
with sounds at the end of their spectrums. Fortunately there is an easy solution,
but first we pause for a question break.
You should correctly answer at least one of these questions before moving
on to the next page.
