A ringtone is the sound that alerts you to an incoming call or text message. They come in many different forms, ranging from recordings of original telephone bells to polyphonic klingeltöne kostenlos that play several notes at once.

Originally, they were designed to be simple and easy to understand, but now a wide variety of ringtones can make your phone ring, and even beep or vibrate. In fact, ringtones are one of the most popular features on mobile phones.

Some ringtones are just plain old, basic melodies, while others can incorporate your voice into the tune. Sing tone ringtones, for example, incorporate your voice over a backing track, similar to karaoke.

Most ringtones are monophonic, meaning that they only play one note at a time. These are the most common and easy-to-understand ringtones, but you can also choose to have polyphonic ringtones, which can play multiple notes at once.

Another type of ringtone is an MP3 ringtone, which uses part of a song as the ringtone melody. These are more common on smartphones than on older models, and you can often download them directly to your device from online music stores like iTunes.

If you want to change the ringtone that plays when you receive a call or message, go to Settings, then Sounds and Haptics. Select the desired sound and tap it to hear what it sounds like.
