Play music for the duration of your slide show
To play a song in the background of your slide show, do the following:
On the Insert tab, select Audio, and then Audio on My PC.
In the file explorer, locate the music file you want to use and then select Insert.
On the Playback tab, select Play in Background.
Do you want to 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.
