RULES
Each question plays two intervals.
Both share the same base note
 (always at reference pitch).
The top note of the second interval
 may be in tune or slightly detuned.
Identify whether the top notes
 are the same,
 or how many cents apart they are.
Reach 100 pts in as few tries
 and as little time as possible.
Correct answers award more points
 the smaller the deviation was
 (if not 0).
Free-Input: ±5¢ tolerance
