iOS 16.2: How to Use the Apple Music Sing Karaoke Feature

Apple Music Sing works with Apple Music's real-time lyrics feature and is available on the iPhone, iPad, and Apple TV 4K (2022). It also lets you control how loud the vocals are in a song. This means that you can sing along with the original artist or turn down the vocals and sing the song yourself.

When a song has background vocals, the lines that are sung at the same time can move separately from the main vocals. This makes it easier to follow. And if there are two or more singers, their voices will be on opposite sides of the screen so that you can sing along more easily.

Apple hasn't said which songs will be able to use the Apple Music Sing feature. All it has said is that it will work with "tens of millions of songs" when it first comes out.

How to use Apple Music Sing on an iPhone or iPad

1. Start playing a song on your iPhone by opening the Music app and selecting a song.
2. Tap the "Lyrics" button (the quotation mark in a speech bubble) in the bottom left corner (if it's there for the song you're listening to).
3. Tap the Sing button, which looks like a microphone and stars and is to the right of the track's progress bar. If it's not there, you can't use the Sing feature for this song.
4. While the song is playing, hold down the Sing button and move the slider up or down to change how loud the vocals are.

When you're done singing along with the music, you can turn off the feature by tapping the Sing button again.

As part of the new feature, Apple Music released more than 50 new playlists that focus on "all the epic songs, duets, choruses, and anthems that people all over the world can't stop singing."
