Question: Experimental music is a general label for any music that pushes existing boundaries and genre definitions . Experimental compositional practice is defined broadly by exploratory sensibilites radically opposed to, and questioning of, institutionalized compositional, performing, and aesthetic conventions in music . Elements of experimental music include indeterminate music, in which the composer introduces the elements of chance or unpredictability with regard to either the composition or its performance. Artists may also approach a hybrid of disparate styles or incoprorate unorthodox and unique elements .

The practice became prominent in the mid-20th century, particularly in Europe and North America. John Cage was one of the earliest composers to use the term and one of experimental music's primary innovators, utilizing indeterminacy techniques and seeking unknown outcomes. In France, as early as 1953, Pierre Schaeffer had begun using the term """" to describe compositional activities that incorporated tape music, musique concrete, and elektronische Musik. Also, in America, a quite distinct sense of the term was used in the late 1950s to describe computer-controlled composition associated with composers such as Lejaren Hiller. Harry Partch as well as Ivor Darreg worked with other tuning scales based on the physical laws for harmonic music. For this music they both developed a group of experimental musical instruments. Musique concrete (French; literally, "concrete music"), is a form of electroacoustic music that utilises acousmatic sound as a compositional resource. Free improvisation or free music is improvised music without any rules beyond the taste or inclination of the musician(s) involved; in many cases the musicians make an active effort to avoid "cliches", i.e., overt references to recognizable musical conventions or genres. 1.

Question: (CNN) -- For the second time in six months, Henrique Capriles Radonski will be in an electoral fight for the presidency of Venezuela.

His opponent is different this time, but the stakes may be even higher: What course will the South American country chart after the death of Hugo Chavez?

In October, Capriles proved to be the strongest challenger the opposition ever fielded against Chavez, yet he still he lost to the charismatic leader by double-digits. But Chavez's battle with cancer kept him from being sworn in, and he died March 5.

On Sunday, Capriles will be in a contest against Nicolas Maduro, the interim president and the man Chavez picked as his successor.

Q&A: Venezuela's presidential election

At age 40, he has been a mayor, a parliament leader, and a governor of a major state who has been given a second chance to win the presidency.

"I am seeking to win the confidence of all Venezuelans," Capriles said recently. "I want a united country. I want Venezuelans to join together (and) work together with a single goal."

The most important issue, he says, is to tackle poverty.

Generous social programs are a foundation of the government that Chavez headed, and Capriles has that he will not do away with them. But he has promised to end the large subsidies that Venezuela provides to Chavez allies.

An attorney, Capriles was elected to parliament in 1998, when Venezuela had a bicameral legislature.

He was just 25 years old at the time, but he quickly advanced to become the president of the Chamber of Deputies and then president of the entire Parliament. 1. What is happening to Henrique Capriles Radonski?
