Disappointment for many budding singers who already saw themselves organizing family karaoke at Christmas: Apple Music Sing requires a latest generation Apple TV 4K, the one released in October 2022, to work. Why ? Because Apple has defined the minimum configuration on an A13 chip to perform this functionality which requires a lot of neural power. However, all is not lost for owners of Apple TV 2021 or earlier, there is a solution called AirPlay video.
With AirPlay, you can display on an old Apple TV the karaoke mode executed from an iPhone or an iPad, provided that it is compatible of course (you therefore need at least an iPhone 11, iPad 9, iPad mini 6, iPad Air 4 or iPad Pro M1 running iOS 16.2).
Start by activating screen mirroring in the Control Center of your iPhone/iPad (button with the two screens) and selecting your Apple TV. The screen of your mobile terminal will then be displayed on your television. All you have to do is activate Apple Music Sing in the Music app (press the microphone in the lyrics view of compatible titles) to see the karaoke appear on the big screen.
