[CLAM] note/chord scoring

[Jean-Luc Menut]

Hello all,

Inspired by Rocksmith (http://rocksmith.ubi.com/rocksmith/en-US/home/) 
and JamOrigin tools (http://www.jamorigin.com/main/), I was wondering 
how difficult it could be to implement, with clam, a system of "scoring" 
single notes and chords made by a guitar plugged on a computer (without 
any effect added).

The goal would be to display notes/chords to a player, to record him, 
and to compare the recording to what was supposed to be played to know 
if it was correct or not.

It seems to be easier than recognize chords from a song because 1) there 
is no other instrument/voice/effect playing at the same time 2) we know 
what is supposed to be played.

Any opinion or advice is welcome

best regards,
Jean-Luc

PS : If you aware of another framework/library more suitable for my 
needs, I'm also interested.
