How to teach Music to a Programmer – II

Well… lots of people already know about Major and Minor mode. On the western music, since the XVII century, we are used to hear another “kind of sound”. The base of our music are major or minor scales, and all of them has the same distance beetwen notes. What I wanna say is that you can hear a D, G, E (major)… scale and you will always hear the distances “T – T – S – T – T – T – S”.

But before the tonalism, the music was wrote on modes. Modes that were used on Greece and then used also by church on midle age.

The music was learnt by all the society, and mathematics and music had same importance. But wasn’t just with numbers that the music had relation. Also with astronomy, sports…

They were used to think that a person should practice all. A man that just practices music would be pretty “female” while one that just practice sports would be rude.
