The features of Powerpoint 2003 are already quite rich, but there is not a single feature that adds background music directly to the entire slide. Although we can insert the music by clicking on the "Insert-movie and sound-File Sounds" method (Figure 1), the music stops when the next slide is shown. So it seems impossible to make the entire slide use a background music.
But that's not the case, and I'm going to share with you the two ways that I've summed up in my practice in PowerPoint to insert background music (this article takes PowerPoint 2003 for example, and other versions refer to operations).
Method One:
1. Click "Insert-movie and sound-sound in File" (Figure 1), in the Insert Sound dialog box that appears, select the file you want to use as the background music, click OK (Figure 2), and click the "Auto" button in the pop-up dialog box to insert the music object (Figure 3).
2. Right-click the inserted Sound object (horn icon), select Custom Animation from the pop-up shortcut menu (Figure 4), in the Custom Animation task pane that appears, click the down arrow to the right of the music option that you just inserted, and then click Effect Options in the menu that appears (Figure 5).
3. In the "Play sound" dialog box that pops up, in the Effects tab, under the Stop playing item, select the appropriate number in the middle number box (Figure 6) by selecting the After (F): xx slide (middle xx is number).
The number can be set according to the total number of slides, such as a total of 49 slides, you can set to 50, so you can achieve until the end of the slide does not reach the set number, so the sound will not stop.
If the inserted sound file is relatively short, you can switch to the Timing tab and select the "until end of the slide" item in the Drop-down list box after repeat (Figure 7), which can be avoided because the sound file is too short to result in a situation where there is no background music to be shown later.
Also, remember to switch to the "Sound Settings" tab and check the "Hide sound icon during slide Show" item (Figure 8) so that the small horn icon will not appear when the show is displayed.
4. Then the slide show to try, is not the realization of the function of the background music.
