Music Appreciation teaching program ??

[William Case]

Hi;

Can anyone recommend a program to download from Fedora repo / any Linux
repo / or the world that teaches Music Appreciation?  

I have something in mind like 'Rosette Stone' but for music.  Something
that really starts with the basics and works up.  

I am think that maybe after 65 years, I can finally learn to recognize
different beats, find out what a harmonic sounds like and discover a
chord.  And then, move on to find out what they are useful for.
