Glassworks

Glassworks is a chamber music work of six movements by Philip Glass. It is regarded as a characteristically Glass-like work. Following his larger-scale concert and stage works, Glassworks was Philip Glass's successful attempt to create a more pop-oriented "Walkman-suitable" work, with considerably shorter and more accessible pieces written for the recording studio. The studio album was released in 1982.

Movements

Philip Glass

Philip Morris Glass (born January 31, 1937) is a classical American composer. He is considered one of the most influential music makers of the late 20th century. His music is also often controversially described as minimal music, along with the work of the other "major minimalists" La Monte Young, Terry Riley and Steve Reich.

Glass has distanced himself from the "minimalist" label, describing himself instead as a composer of "music with repetitive structures". Though his early mature music shares much with what is normally called "minimalist", he has since evolved stylistically. Currently, he describes himself as a "classicist", pointing out that he is trained in harmony and counterpoint and studied such composers as Franz Schubert, Johann Sebastian Bach, and Wolfgang Amadeus Mozart with Nadia Boulanger.

Glass has founded his namesake musical group, the Philip Glass Ensemble, with which he still performs on keyboards, and has written operas, musical theatre works, ten symphonies, eleven concertos, solo works, chamber music including seven string quartets and instrumental sonatas, and film scores. Three of his film scores have been nominated for Academy Awards.

Glass

Glass is a non-crystalline amorphous solid that is often transparent and has widespread practical, technological, and decorative usage in, for example, window panes, tableware, and optoelectronics. Scientifically, the term "glass" is often defined in a broader sense, encompassing every solid that possesses a non-crystalline (that is, amorphous) structure at the atomic scale and that exhibits a glass transition when heated towards the liquid state.

The most familiar, and historically the oldest, types of glass are based on the chemical compound silica (silicon dioxide), the primary constituent of sand. The term glass, in popular usage, is often used to refer only to this type of material, which is familiar from use as window glass and in glass bottles. Of the many silica-based glasses that exist, ordinary glazing and container glass is formed from a specific type called soda-lime glass, composed of approximately 75% silicon dioxide (SiO₂), sodium oxide (Na₂O) from sodium carbonate (Na₂CO₃), calcium oxide, also called lime (CaO), and several minor additives. A very clear and durable quartz glass can be made from pure silica which is very tough and resistant to thermal shock, being able to survive immersion in water while red hot. However, quartz must be heated to well over 3,000 °F (1,650 °C) (white hot) before it begins to melt, and it has a very narrow glass transition, making glassblowing and hot working difficult. In glasses like soda lime, the other compounds are used to lower the melting temperature and improve the temperature workability of the product at a cost in the toughness, thermal stability, and optical transmittance.
