##### Age 14 to 16 Challenge Level:

Using an understanding that 1:2 and 2:3 were good ratios, start
with a length and keep reducing it to 2/3 of itself. Each time that
took the length under 1/2 they doubled it to get back within range.

##### Age 14 to 16 Challenge Level:

The Pythagoreans noticed that nice simple ratios of string length
made nice sounds together.

##### Age 14 to 16 Challenge Level:

The scale on a piano does something clever : the ratio (interval) between any adjacent points on the scale is equal. If you play any note, twelve points higher will be exactly an octave on.

##### Age 11 to 18

The reader is invited to investigate changes (or permutations) in the ringing of church bells, illustrated by braid diagrams showing the order in which the bells are rung.

##### Age 11 to 14 Challenge Level:

Suppose you are a bellringer. Can you find the changes so that,
starting and ending with a round, all the 24 possible permutations
are rung once each and only once?

##### Age 7 to 16

An article for students and teachers on symmetry and square dancing. What do the symmetries of the square have to do with a dos-e-dos or a swing? Find out more?

##### Age 11 to 14 Challenge Level:

Bellringers have a special way to write down the patterns they
ring. Learn about these patterns and draw some of your own.
