We can think of speeches organized chronologically, step by step, or spatially as following a “natural” or self-evident structure. When you’re talking about a process, for instance, walking the audience through the process step by step seems like a logical or natural choice.

Remember, though, that even if your speech is structured in a “natural” sequence, you still need an introduction that helps the listener understand why they’re listening to this story. Imagine that a friend is going to tell you a story about something that happened to them that day. First, let’s imagine that they start the story with “Something really funny happened to me . . . .” What are you listening for in the story? Now imagine if they started the story with “I’m really upset because of something that happened today.” Or “I really need your advice. Here’s what happened . . . .” With each of these different beginnings, we listen in a different way. In the first case, we’re primed to laugh; in the second, we get ready to offer comfort and sympathy; in the third, we’re prepared to problem solve. The same is true of the beginning of your speech: by setting the stage with the introduction or the “hook,” you’re letting the listener know what they’re listening for and how they should listen.

Chronological

A persuasive speech about Climate Change might describe the predicted effects of global warming in chronological order.

A chronologically organized speech pattern organizes its main points following a sequence of events or occurrences according to the time they took place. This structure works particularly well for informative and introductory speeches. For example, an introductory speech about the life events that lead you to attend your college could be organized chronologically starting with the first meeting with your guidance counselor, which lead to filling out an application a few weeks later to then drafting an essay, going on a campus tour a few months after that, having an interview with the department, and then finally getting the acceptance letter. Another example of a chronological speech topic would be a speech about a historical event, such as the Triangle Shirtwaist Factory Fire, the Boxer Rebellion, or the Arab Spring, which covers the events that occurred in the order in which they happened.

The advantages of a chronological speech pattern are that it is very easy to follow and it creates a clean, clear order. The timeline does the organizational work for the speaker and makes it easy to use. The cons are that there may be many events that occurred, such as in a speech topic about women getting the right to vote, which may not fit into the speech delivery time limit. So, consider the time allotted in addition to whether the time sequence of events is the most effective way to present the material before selecting this pattern.

Step-by-Step

An informative speech about Salsa dancing might give step-by-step instructions.

This pattern presents the steps involved in doing something and is useful for “how-to” or demonstration speeches where you are teaching or showing how to do a task. It follows the order of a process. For example, the steps involved in baking a cake, a speech demonstrating the dance steps required to do the Macarena, or how to create a PowerPoint presentation would use a step-by-step structure.

The advantage of this organizational pattern is that it breaks the task into small pieces for the audience. It allows them to see the process of doing something so that they may be able to do it themselves. The disadvantage of this pattern is that it can be tedious or repetitious if listeners are already very familiar with some of the steps in the process. With this organizational pattern, it’s particularly important to know how much prior knowledge of the process your audience already has.

Spatial

An informative speech about the International Space Station might use a spatial organization pattern, giving the listeners a tour of each part of the station as though they were moving through it.

A spatial pattern organizes each main point in a directional structure, connecting each main point to a whole. This structure is used for informative speeches where the topic is organized by location, geography, or moving through a space (“spatial” is the adjective form of “space”). For example, a speech about the parts of a resume might move in order from the top section to the bottom section. A speech about the regional cuisine of Germany might move from the Northwest region in a clockwise direction around the country. A speech about a building might start at the front doors and end on the roof. A speech about the pathway of Hurricane Sandy would include the geography showing the path moving from south to north east.

The spatial pattern is particularly useful if you want your listeners to be able to visualize an entire place or a complex object, since it moves between the part and the whole in a visual way. If you want your audience to visualize the Statue of Liberty, for instance, you might describe it spatially from top to bottom, rather than telling the story of its construction (chronological) or talking about the various things it has come to symbolize (topical).
