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.

Lisa was running late. Lisa, 25, had a lot to do at work,plus visitors on the way: her parents were coming in for Thanksgiving from her hometown. But as she hurried down the subway stairs, she started to feel uncomfortably warm. By the time she got to the platform, Lisa felt weak and tired-maybe it hadn't been a good idea to give blood the night before, she thought. She rested herself against a post close to the tracks.

Several yards away, Frank, 43, and his girlfriend, Jennifer, found a spot close to where the front of the train would stop. They were deep in discussion about a house they were thinking of buying.

But when he heard the scream, followed by someone yelling, "Oh, my God, she fell in!" Frank didn't hesitate. He jumped down to the tracks and ran some 40 feet toward the body lying on the rails. "No! Not you! " his girlfriend screamed after him.

She was right to be alarmed. By the time Frank reached Lisa, he could feel the tracks shaking and see the light coming. The train was about 20 seconds from the station.

It was hard to lift her. She was just out. But he managed to raise her the four feet to the platform so that bystanders could hold her by the arms and drag her away from the edge. That was where Lisa briefly regained consciousness, felt herself being pulled along the ground, and saw someone else holding her purse.

Lisa thought she'd been robbed. A woman held her hand and a man gave his shirt to help stop the blood pouring from her head. And she tried to talk but she couldn't, and that was when she realized how much pain she was in.

Police and fire officials soon arrived, and Frank told the story to an officer. Jennifer said her boyfriend was calm on their 40-minute train ride downtown-just as he had been seconds after the rescue, which made her think about her reaction at the time. "I saw the train coming and I was thinking he was going to die." she explained. What are the answers to this following set of questions: 1. Who was ariving for thanksgiving?
