Please get your datatypes straight. The return value isn't "false", it's false. The inputs aren't "1" and friends, they're 1 and friends. Please format "1/4" as "1/4". Also, inconsistent return value datatypes ( tonyli's issue ).

If the values in array are exactly the same as one quarter note

This is incorrect. If they add up to one quarter note .., do something.

Adding the puzzle tag does not make these things right. That tag is somewhat appropriate though, because there's a lot of superfluous information in the description. It's nice for flavour, but absolutely unnecessary for solving the kata - maybe put it in a separate section people can skip if they don't actually want to learn music theory and just want to add some numbers?

• half of the needed info to solve this isn't given in the description.
• we already have katas about time signatures, and built in a better way (https://www.codewars.com/kata/57091b473f1008c03f001a2a) hence, "yet another duplicate" after your multiply one.

No random tests

Different return types are bad

Serioulsy...?

• inputs aren't described properly
• no random tests
• like... yeah right, you didn't do the basic "multiply" kata when you subscribed... x(
• the task has no interest.
• no blocks in the test suite
