Types of ring tones

Monophonic - A monophonic ringtone is a series of musical notes, one note at a time.

Polyphonic - A polyphonic ringtone can consist of several notes at a time.
The first polyphonic ringtones used sequenced recording methods such as MIDI. Such recordings specify what synthetic instrument should play a note at a given time, and the actual instrument sound is dependent upon the playback device. Later, synthesized instruments could be included along with the composition data, which allowed for more varied sounds beyond the built-in sound bank of each phone.

Truetone - Truetone is an audio recording, typically in a common format such as mp3, m4a or aac. Truetones, that are often an excerpts from songs, have become very popular as ringtones.
