Setting up a custom alarm tone is a new feature in iOS 7. All your iPhones and iPads running iOS 7 can have a custom alarm tone instead of the default set of tones that iOS ships with.
This is a short tutorial and a very basic one at that. If you've figured out the process already, please feel free to skip to other articles of interest.
How to Set a Custom Alarm Tone on iPhone, iPad, and iPod Touch
Step #1. Open the Clock app on your iDevice.
Step #2. Select the Alarm Clock icon from the menu (bottom.)
Step #3. Add a new alarm by tapping on the ‘+‘ sign on top-right. Or, tap on Edit to edit an alarm clock already set.
Step #4. Tap on Sound.
Step #5. Scroll up and under SONGS tap on Pick a Song.
Step #6. Pick a song from the playlist (or any part of the music app.)
Step #7. This will be now set as the alarm tone
That's it! Simple, right?
When I first set out to set a custom tone for the alarm, there were no songs under SONGS. Instead, there was only Pick a Song. Obviously, you need to tap that and then add a song. I think you might have to do it for every song.
You can also buy ringtones through iTunes store and have them added to the list. In that case, you will be choosing the tones from under the ringtones section of the screen.
