I still have a problem determining the "established core" (like "classical cuban mambo")
So during a time-line, some African slaves were brought to Cuba (and States), where they also brought their culture - dance and rhythm. It mixed with local culture, and also with some imperial European culture. So, it changed considerably. Then, this mixture was gradually exported to States, and it was also slightly modified even during export. Then it was mixed with various influences in the States, some of it re-imported to Cuba and re-exported again several times. There was also some route via neighbor countries, like Mexico, Argentina etc ... From States, this mixture gradually drifted all around the world, changing further - in States and around the world. In Cuba this mixture also continued changing. Connections between these two paths were partially broken because of embargo
I think if we get bogged down in details, then we will miss the wood for the trees.
To simplify, salsa's musical roots are the Son. Change that core, then you will be left with something else.
Salsa the dance, as you correctly mentioned is also a mixture of different elements, with a strong African presence. That presence is in its cores. You have Eurpean and other elements. Actually, if Terence is reading this I would appreciate his view on the proportion of the indigenous influence, if any on the actual dancing, as to me, at least in its original form it looks like the African element is the dominant factor, followed by what was fused from Europe.
Anyway, staying on the simple view. The core of salsa and its main flavor seems to be Africa, both musically and dance wise. If we agree on that, then lets take it decades ahead when what we know as mambe/salsa were developed. On this modern phase the elements of the barrio and the street elements, where salsa had made its modern home were injected into the music and the dance (Terence may want to interject to correct/elaborate).
If we loosely agree on the above, then we need to see those elements when quality salsa music is being played. We can do so by watching the rhythm section: Congas, bongos and timbales, representing Africa. The maracas and guiros, representing the indeginious influence. The piano, wind section, etc. representing Europe. The singers, or for real salsa, the soneros, will have the ability to improvise on the spot when singing live, to tell their stories and sometimes humorous statements. That will come from Spain and the trovador culture, which many believe were taken there by the Moors (Arabs/North Africans), earlier on in their history.
So, when you see a concert of salsa when authentic music (I bet someone is going to ask me to define authentic salsa music, as well...LOL), you should see a sonero improvising, at some stage at least, and you should see all the cultural influences playing together in coherence, while providing room for improvisations ('communication'?) on the part of the musicians. The base of all this will be the strongly African influenced rhythm section. The lyrics will many times be
street influenced, about anything from love, betrayal, bad boys and even gun fights.
By the same token above, the dance should reflect the musical elements. Question. When you walk into an average salsa club near where you live, how much of the core African or Black, if you like influence do you see? If any of the main influences that made the original music and dance diminish too much, then you are going to have the core of the music and the dance effected.
So, Christian culture has, for instance, a reference point - it is year "1", connected with Jesus and with Earth traveling around the Sun. Everything regarding date and time is referencing that point.
In my humble opinion, the Christian culture is nothing but a pagan Sun God religion, with an astrological base of course, packaged to be sold under a new name and agenda. Jesus, representing the Sun (his images with rays shooting out from behind his head), and his 12 disciples representing the 12 signs of the zodiac/months of the year. His birth 25th of December correspondes to the Winter Solstice - a pagan symbol of re
birth, among other things and traditionally a time of celebration and festivities (that rings a bell to me). There are many other astrological 'correlations' within this cult or religion and it makes for fascinating readinga and area of research, specially when you see how connected the whole cult is with politics and political secret societies, where the real decisions are made.
So, not to loose the plot, the religion of Christianity is basically a religion of astrology and other occult practices from Rome and going back far beyond in time, where those who are on the top of the pyramid know it, and look to these as a source of knowledge and power, while the masses, the 'sheep' if you like, were fed a symbolic mumbo jumbo, to mind control them. The witch hunts where so many women and men were tortured and burnt, were nothing but this priesthoods attempts to control the same knowledge they lived by and take it out of the public domain.
Why did I go into so much detail about this popular sun cult in a salsa discussion? Just to demonstrate when a set of popularized/sanitized occult belief systems that is more than 2000 years old is capable of hoodwinking, millions of people, including even scientists and intellectuals on the planet for centuries, playing a great role in wars and mass murder, up to now, the age of the computers and space travel, then it is relatively easy for people to be 'misdirected' in something like a 'trendy' hobby such as modern salsa dancing, yoga, tai chi and anything else which is imported, where it is difficult to identify valid sources of references. It is a piece of cake! Shake the modern salsa dancer's reality tree then you get a 'religious' backlash.
Unless you take a somewhat scholarly approach.
That is what we are trying to say here on one level - Terence, Salsera Alemana, EL Che, DJ Yuca and Toca Timba.
People insist on seeing this within a limited paradign of " my 'style' is better than yours", because they want to and it facilitates a meaningless argument, which will take them from the ultimate truth that is being attempted to get across to them.
What and where is this "reference point" in salsa
So again, if you see people dancing salsa, but you do not see the black and the street influences as a major element in that dancing, then you are seeing a over sanitized 'sellable' version make for public consumption. That is the bottom line!
It is unfortunate that it is not usually possible to sanitize and/or standardize a rich art form without messing with its core., and again, change the core too much, then you end up with something else.
