There are three types of ringtones: monophonic, polyphonic or musical. Monophonic ringtones have short tunes played with simple tones. In contrast, polyphonic ringtones have multiple tones that can be played simultaneously using instrument sounds such as guitar, drums, piano, etc. Finally, music ringtones, also known as musical ringtones, voice tones, real tones, sing tones or true tones, include actual parts of music songs.
