Nokia 3100 supports so called polyphonic ringing tones. 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. Your phone has sound components from over 40 instruments that can be used for polyphonic sounds but the phone can play four instruments simultaneously. The phone supports the Scalable Polyphonic MIDI (SP-MIDI) format.

You can receive polyphonic ringing tones via multimedia service, or download them via the gallery menu, or via the PC suite. If you receive ringing tones via multimedia message, you can save the tone to Gallery > Tones folder. To select ringing tones saved in the Gallery, select Open gallery from the ringing tone list.

You can use Nokia Sound Converter to edit ringing tones to be compatible with your phone. Nokia Sound Converter is a part of the Nokia PC Suite. With PC Suite you can also transfer ringing tones to your phone. Click here to download the Nokia PC Suite for Nokia 3100
