[Tutor] Sound, frequencies and chords

[Mr Gerard Kelly]

Hi everyone, I'm a python noob but I have an ambitious (for me) goal: I
want to make a simple program that allows you to hear combinations of
notes according to a vector of frequencies.
 
Does anybody know any module that allows you to input a frequency in Hz
and returns a sound with that frequency, and lets you do that with
multiple frequencies, so that you can build chords? I've googled around
but I can't find what I'm looking for. I don't want MIDI since from what
I know it only lets you choose from 12 notes (C, C#, D, D#) etc., but I
want the full range of frequencies.

If you can let me know about anything, I'd really appreciate it, thanks!
