A question asked a lot is how to create a ringtone from iTunes for a song. Here are step by step instructions with pictures.

1. Find out the start and stop points of the ringtone in the song, no more than 30 seconds
   In this case, I want the first 25 seconds of Buttons by The Pussycat Dolls:
   
2. Right click song and choose “Get Info”
   
3. On the Options tab, set the start and stop times, from step 1
   
4. Select OK
5. Right click song again and choose “Create AAC Version”
   
6. Look for new version of the song with a time of 30 seconds or less
   
7. Right click song and choose “Show in Windows Explorer”
   
8. Rename file from .m4a to .m4r
   
9. Drag back into iTunes
   
10. The ringtone has been created. Sync your phone
    
11. Remember to set the original song back to normal start and end times. Right click song and choose “Get Info”On the Options tab, unset the start and stop times.
