The title master exists to give you additional design options. Use it to make unique style changes just to the title slide (or slides) in a show.
What's a title slide? It's any slide in your show that uses a Title Slide layout. This is the default layout for the one slide automatically included in a new, blank presentation.
The Title Slide layout is often used for a slide that introduces a new section of a slide show. Thus, you might have several title slides in one show, and that's where a title master becomes helpful. You'll experiment with this master in the practice session.
Note There is a connection between the text styles on the slide master and those on the title master. The title and first level of body text (top bullet) on the slide master relate to the title and subtitle text on the title master.
An example of how you might experience this: You change styles to the title and subtitle on the title master, making them boldface and centered. On the slide master, you then make different changes to the title text and top-level body text: you change the font type, and make them flush left in alignment. You then look at the title master again and — oops, its title and subtitle have taken on the changes you made to the slide master text.
Advice: Make text changes to the slide master first, and then to the title master. If you do it in that order, your customizations on the title master are always preserved.
