Polyphonic
sound consists of several sound components played at the
same time like a real melody through a speaker. Polyphonic
sounds are used in ringing tones and message alert tones,
for example.
Your phone has sound components from over 43 instruments
that can be used for polyphonic sounds, but the phone
can only play four instruments simultaneously. The phone
supports Scalable Polyphonic MIDI (SP-MIDI) format.
You can receive polyphonic ringing tones via your multimedia
messaging service.
