What is a Polyphonic Ringtone and a Monophonic Ringtone?

Solution:  Monophonic ringtones: These ringtones are simple because the phone can only generate one sound or beep at a time. The tune of the ringtone consists of a series of sequential beeps at different frequencies.

Polyphonic: These ringtones have the ability to generate up to 16 separate sounds at the same time. This makes for music that is much richer and the tunes are typically more recognizable.
