(soloist John Harrison) Baroque Music Characteristics Here is an extract from Vivaldi’s Four Seasons: (Performed by the Orchestra Gli Armonici) Here is the Hallelujah from Handel’s Messiah: Here is Gloria in Excelsis Deo by Bach performed by The Netherlands Bach Society: Let’s have a listen to some of their work. Johann Sebastian Bach (composed over 1,000 pieces of music!!), George Frederic Handel (wrote The Messiah) and Antonio Vivaldi (The Four Seasons and Gloria remain very popular) are considered to be the most famous Baroque composers. It is not surprising, therefore that the music composed and performed at the time similarly stretched the boundaries of what had been heard up until this point. Great artists such as Rembrandt and Caravaggio were developing new techniques in the world of art. It was also a time of great scientific discoveries – (think of individuals such as Gallileo and Sir Isaac Newton) and new lands were still being explored. In Europe, the 30 years war (1618-1648) was being raged and powerful rulers such as Louis XIV in France, Charles II in England and Peter The Great in Russia reigned with considerable ruthlessness. The Baroque period was a very eventful period of history. We are going to have a look at the following: New instruments were also invented and the tonality of major and minor keys was firmly established. It was a time of great musical development as famous Baroque composers, such as Bach (his death in 1750 is typically seen as being the end of the Baroque Period), Handel and Vivaldi created grand works.

Then we'll have a more complete story of how hair color works. Hopefully soon we'll have a better handle on the genes that decide how much pigment to add. Other genes decide how much dye to add to the paints.Īll of these genes work together to determine how much red and how dark the hair should be. The MC1R gene determines if red will be added or not. Only these genes are determining how much eumelanin is in the hair, not pheomelanin. And the oranger haired child inherited some of each.Īnd this is how it works for people who don't have red in their hair too. The child with auburn hair inherited mostly H's. So in theory, a child could be anywhere between HHhhhhhh (strawberry blonde) to HHHHHHHH (very dark red hair). Remember, your kids will get 4 copies of the gene from each of you and that the number of on genes adds up to give a hair color. Let's say you are HHHHHHhh and your husband is HHHHhhhh. You said you have auburn hair and your husband has red-orange hair. Using this system, someone with very dark hair would be HHHHHHHH and a very light haired person would be hhhhhhhh. If one of these hair color genes is on, we'll represent it with H and if it is off, we'll represent it with h. Remember you get one copy of each gene from your mother and one from your father giving you a total of eight copies of these hair color genes. What about your case in particular? Let's say that there are four genes that determine how dark someone's hair is. MC1R isn’t the only gene that affects hair color! These mice have a difference in their ASIP gene, which causes this hair color difference. So they end up with red hair and freckles. In redheads, the MC1R gene no longer works resulting in a build up of pheomelanin. People who don't have red hair convert most of their pheomelanin to eumelanin using MC1R. There is a single gene that can determine whether someone will have red hair. How does the body know how much pigment to make? And which ones? Genes of course. If you add a little red, then you end up with pink. And a more orangish redhead has lots of this pigment. In the same way, strawberry blonde has just a bit of pheomelanin. Brown has more and black hair has a whole lot of eumelanin. It is the amount of each of these that determines hair color.īlonde hair has just a bit of eumelanin. Our bodies make at least two different pigments, eumelanin and pheomelanin. What do all these hair colors have in common? A pigment called pheomelanin. They can have strawberry blonde, almost orange, auburn and mixtures of all three. You are right in saying that almost always, two redheads will have kids with red hair.īut as your family shows, this doesn't mean that all of the kids will have the same shade of red.
