Let's take a look at the sampled content banks that come with Garageband. Click on the eye icon in the lower left corner. You'll see the box open up giving you several different categories of samples.
The thing to remember here is that most of your samples will be of varying tempos, keys, and time signatures. However, in the samples that come with GarageBand out of the box, there's not a lot of variety. When choosing a sample, keep in mind what you need for your particular song.
You have the choice of samples by type, which includes guitars, strings, drums, and percussion; by genre, including urban, world, and electronic; and by mood, including dark, intense, cheerful, and relaxed.
Now, let's look at actually using a sample.
