Ringtones in different categories
"Monophonic" plays a single note/sound at a time. (Somewhat like playing the piano with one finger only).
"Polyphonic" plays many notes/instruments at the same time. In general, with phones, this refers to so called MIDI format sound files ( MIDI = Music Instrument Digital Interface or somesuch; I didn't google to check the acronym 😉 ). Phones in general also support a MIDI format called SP-MIDI (SP = Scalable Polyphonic). To use the same analog, polyphinic MIDi is like the whole orchestra (multiple different instruments playing at the same time). There are variations in devices as to how many simultaneous instruments they support (e.g., 4, 16, 40 simultaneous sounds, or whatever).
You can also use other digital audio formats that can reproduce multiple, simultaneous sounds, but they're not using a MIDI (software or hardware) sound generator. Those formats are such like WAV or MP3.
