You can add a song to a presentation and play it across slides in the background of your slide show.
If you want to use music from the web, you have to download it to your computer before you can use it in a presentation.
To play a song across slides
-
On the Insert tab, select Audio, and then Audio on My PC.
-
In the file explorer, browse to the music file you want to use, and then select Insert.
-
With the audio icon selected on the slide, on the Playback tab, select Play in Background.
Play in Background makes the audio file start automatically during a slide show and also makes the audio play across multiple slides.
Play multiple songs across multiple slides
If your slide show is longer than one song, you can add more songs. However, if you find that you're having trouble synchronizing the music with the slide show, you can use a third-party audio editing tool, such as Audacity®, to string the songs together into one file so they play continuously throughout the slide show.
