## Polyrhythm Trainer (#194)

Greetings fellow Rubyists,

This week's quiz is to create a polyrhythm training program. The user
will be prompted to tap out a rhythm with two keys: left and right.
Each time the user presses a key the program will display how close to
the correct timing the key press occurred. The program will be
configurable to train the user in any polyrhythm 2:3, 5:4, 11:17, and
so on. The program will also have a configurable tempo. After a number
of complete rhythms the program will display the ratio of how many
notes were successfully struck, success determined by being within a
threshold around the perfect timing.

The display can be as simple as a console application or use a full
graphical interface. [Ruby Inside][1] recently had an article about
graphical toolkits if you are interested.

[Polyrhythm][2] is the simultaneous sounding of two or more independent rhythms.
