Someone Has Invented a Grand Piano Only Cats Can Hear (And There’s an Album, Too)

Cats have awesomely good hearing. While most humans top out at 15,000 hz, cats can detect sounds up to (and maybe beyond) 64,000 hz. That’s eleven octaves, one more than even a dog. It helps them hunt prey.

This got some scientists thinking “Well, if we’re going to make music for cats, then we should be sure to use their entire hearing spectrum!” The result is a special grand piano that, when played in its upper registers, can only be heard by felines.

To test it out, a pianist performed a series of songs for a row of cats. Selections included some national anthems along with Jay Z and the Backstreet Boys. According to video shot during the experiment, the cats really seemed to dig it.

Should you have a cat and wish to provide him or her with some recorded musical enjoyment, there’s an album available. Here’s the track listing via The Daily Mail.

An album for cats is available to the public and includes the ultrasonic feline-friendly versions of national anthems belonging to internet-censoring countries.

The track list reads:

1. China – Yiyongjun Jinxingqu (‘March of the Volunteers’)

2. Iran – Mehre Khavaran (‘Eastern Sun’)

3. North Korea – Aegukka (‘Patriotic Song’)

4. Turkey – Istiklal Marsi (‘Independence March’)

5. Russia – Gosudarstvenny Gimn Rossiyskoy Federatsii (‘State Anthem of the Russian Federation’)

6. Saudi Arabia – an-Nasid al-Wataniyy (‘The National Anthem’)

7. Vietnam – Tien Quan Ca (‘The Marching Song’)

8. Cuba – El Himno de Bayamo (‘The Bayamo Anthem’)

9. Myanmar – Kaba Ma Kyei (‘Till the End of the World’)
