A ringtone is the sound made by a mobile or cell phone to indicate an incoming call. Technically, a ringtone is a program that activates the phone's speakers anytime it picks text messages or incoming call signals. Ringtones are based on a programming language called Ringing Tone Text Transfer Language (RTTTL) which was developed by Nokia.



Purpose of ringtones is to give a unique ring to a mobile phone so that it can be distinguished in an environment that has lots of mobile phone users. Almost all the newer phones from manufacturers like Motorola, Samsung, Siemens, Sony-Ericsson, LG, Sanyo, Panasonic now have ringtones capabilities. Ringtones are basically monophonic ringtones and polyphonic ringtones.

Early phones had the ability to play only monophonic ring tones. It comprises of a series of sequential tones at varying frequencies.

The difference between a regular monophonic ringtone and a polyphonic ringtone is equivalent to the difference between a solo flute player and the whole orchestra. Polyphonic ringtones can be played on mobile phones which are capable of playing more than one tone simultaneously. All the latest models support polyphonic ringtones. Many phones are now able to play more complex polytones; up to 128 individual notes with different instruments are played simultaneously to give a more realistic musical sound.

While polyphonic tones were better than monotones, they still sounded more like an old video game than the music they were patterned after.
