You can add background music to your Tella video from Tella’s built-in music library, or upload your own track. You can also preview tracks, adjust the volume, and remove or replace music at any time.

### Open the audio tab

1. Open your video in the Tella editor.

2. Select the **audio** tab.

### Browse and preview Tella’s background music

1. In the audio tab, browse the background music that is available.

2. Select a track to preview it.

3. Click **Play** to hear how it sounds.

4. Use the seek control to skip around and preview different parts of the track.

5. Browse the full set until you find a track you like.

### Add a track to your video

1. When you find a track you like, select **add**.

2. The full track is added across the full duration of your video.

### Adjust the music volume

1. Use the volume control in the audio tab to make the music louder or quieter.

### Remove or replace the track

1. To remove the current track, select the remove option in the audio tab.

2. Add a different built-in track, or upload your own to replace it.

### Upload your own background music

1. In the audio tab, select **upload**.

2. Choose an audio file from your computer.

This is useful if you have branded music, something you created yourself, or a custom track.

### How Tella handles track length

* If your background track is longer than your video, Tella fades it out at the end of the video.

* If your background track is shorter than your video, Tella loops it so you have music for the full duration.

### Preview your video with music

1. Click **Play** to preview the video with your background music.

2. If needed, adjust the volume until it sounds right.
