When editing PowerPoint templates or creating new presentations from scratch, you might want to insert a narration or add music to PowerPoint. There are two methods by which you can insert music into your PowerPoint slides and control how it is played.
Adding Music to PowerPoint using an Audio File
You can add music to PowerPoint by using an existing audio file via Insert > Audio > Audio on my PC.

Select the music file from your device to insert it into your PowerPoint presentation.

Once the audio file is added, you can drag and drop the audio icon to place it in your slide or keep it hidden via the Playback tab by checking the Hide During Show option. The Playback tab also lets you control whether to start the music by clicking or automatically.

You can also play the music in a loop and across all slides instead of just one. Other options allow you to preview audio, trim the music file, add a fade duration at the beginning and/or end of the audio track, and adjust the volume.

Adding Music to PowerPoint by Recording Audio
You can also record audio to insert a song or music into PowerPoint. You can use this feature if you intend to add a background score by recording it using a mic. Such as recording Live playback music. To start recording your mic and computer audio, go to Insert > Media > Audio > Record Audio.

Click the Start button to begin recording music from your connected mic.

Once the recording is complete, click Stop to insert the audio into your PowerPoint presentation. Once the audio file is added, you can manage playback settings via the Playback tab to play the video across or a single slide, trim audio, add fade effect, play in a loop, hide in the slideshow, and adjust other options according to need.

While many PowerPoint users might ask the question as to how to add music to a PowerPoint presentation, the process is the same as adding or recording audio in general. The same process can also be used to add narration, be it from an existing file or by recording it.
