1. Select the song you want to be a ringtone in the iTunes music list, and right-click and select "Show Introduction"; Enter "options", including "start time" and "end time", and randomly intercept a time period less than 40 seconds (I usually only choose "end time" and fill in "0:30" and so on. ), and then click OK.
