An iPhone 7 can use a song from your music library as the sound for a Clock alarm when the song is available to the device and supported by the installed iOS version. This changes one alarm’s sound; it does not change your ringtone.
Choose a song for an alarm
- Open the Clock app.
- Select Alarm.
- Create a new alarm or tap an existing alarm to edit it.
- Select Sound.
- Choose the option to pick a song from your music library.
- Select the song, return to the alarm settings, and save the alarm.
Make sure the song is actually available
Streaming-library status, downloads, subscription changes, and digital-rights restrictions can affect whether a track is usable when the alarm fires. For an important wake-up alarm, test it before relying on a particular song and keep the iPhone charged.
Alarm volume is separate from media playback
Turning down a song in the Music app does not necessarily set the alarm’s alert volume. Review the iPhone’s Sounds & Haptics settings and test the alarm at the volume you expect.
If the song does not play
Choose one of Apple’s built-in alarm sounds to determine whether the Clock alarm itself works. If built-in sounds work but the selected track does not, download the song locally when supported or choose another compatible track.
The iPhone 7 is a legacy device and cannot run current iOS releases. Menu labels and Apple Music behavior may differ from newer iPhones, and the device no longer receives current iOS security updates.
