How to teach Music to a Programmer – II

Posted by rafinhaviolino en agosto 18, 2008

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. But a detail: wasn’t the practice of the music that the church learnt from Greece. Just the theory. On truth the church did all that they could do to finish with the Greek music. Just as they did to “erease” all that wasn’t from and for God. In fact, the church modes originated in the 9th century. Authors from that period misinterpreted a text by Boethius, a scholar from the 6th century who had translated the Greek musical theory into Latin. But about the music from church on midle age we talk soon 😉

How to teach Music to a Programmer – I

Posted by rafinhaviolino en agosto 11, 2008

Music is not something that is closed to a group of people. Everybody can hear music, sing or dance. But the music had different meanings in the past and here I will try to explain a little of the little that I know.

The word “music” came of the “muse”. This is because the Ancient Greeks were used to see the music as a thing to find the beauty and truth. On that time they believed that the music was a gift from the gods, and that it could cure diseases and do miracles.

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.
