Mobile phone ringtone question

I am looking for a ringtone because i do not like any of the ones native to my phone, or those that I find all over the net. I am specifically looking for the soft ringtone I hear in various TV series. Kind of a non-intrusive soft ring of say 5 notes or so… If anyone has any idea about what I’m talking about, (or wish to recommend one) please leave a link… thanks
