Definition of tosca - What is it, Meaning and Concept

Tosco (or its female version: tosca ) is an adjective that is used to rate the person who lacks literacy, academic training or good manners .The concept is also used to refer to what is gross, rustic, uncivil or gross .

For example: “I don't like receiving orders from such a crude person, but he is my boss and I must abide by what he says” , “The grandmother was a coarse woman with few words, although she knew how to prove her honey ”, “ Don't be coarse! How do you think of opening the can with a hammer? ”.

A tosca can also be a rock porous that develops with fresh water lime.Also known as toba calcarea , the tosca It is part of the group of limestone since it is mostly composed of calcite.

The process of formation of a rough begins with the rain.This water has a reduced amount of carbon dioxide and minerals; when it reaches the ground, it begins to be loaded with carbon dioxide from the activity carried out by the bacteria and the plants, thus, the liquid dissolves calcareous rocks as it moves through the underground substrate, taking carbonate and calcium.The water then emerges through rivers, waterfalls or springs and loses carbon dioxide, precipitating calcite.Finally, these crystals begin to form a calcareous crust on the plants and their superposition derives in the creation of the rough ones.

validTosca† , finally, is the name of a opera written by Giuseppe Giacosa and Luigi Illica with music composed by Giacomo Puccini , which premiered in 1900 at the Costanzi Theater in Rome.It is based on a drama by Victorien Sardou entitled « La Tosca «, published in 1887 in Paris, and starring Sarah Bernhardt , one of the great actresses of the time.

The intensity drama that characterizes this opera by Puccini, as well as the beauty of some of its arias have made it one of the most relevant in the repertoire called verista , Italian music, which is characterized by an aesthetic that, towards the end of the 19th century and the beginning of the 20th century, began to show reality without idealizing it (this movement can also be called "realism").

In the history of Tosca we find some of the elements that most attract the public of the opera: love, passion, violence, intrigue and, almost inevitably, death .It is an unforgettable journey that manages to take the emotions of the public to the extreme, and in this the development of the characters plays a fundamental role, achieved in a masterly way both in the protagonists (Floria Tosca and Mario Cavaradossi) and in the antagonist (Baron Scarpia).This opera is among the three best known of the Italian composer, next to La Boheme and Madama Butterfly .

With respect to the musical structure of Tosca , it is very different from the division in arias that characterizes many of the most famous opera in history, from composers such as Mozart, Rossini or Verdi, although according to what Puccini had been developing until then: the discourse is continuous and they only break it or two arias.If we take The Barber of Seville (from Rossini), for example, we will notice that the work is divided into dozens of pieces, all well defined and properly titled for easy identification; Tosca , on the other hand, has extensive sections that merge together almost imperceptibly.

This makes it difficult to interpret any of its parts in the context of a concert; however, his two arias E lucevan le stelle , by Mario, and Vissi d'arte , from Tosca, have been sung in a host of recitals, and many tenors and Sopranos from all over the world continue to include them in their repertoires.
