Oboes are usually made of wood, but there are also oboes made of synthetic materials. A soprano oboe measures roughly long, with metal keys, a conical bore and a flared bell. Sound is produced by blowing into the reed and vibrating a column of air. The distinctive oboe tone is versatile, and has been described as "bright". When the term "oboe" is used alone, it is generally taken to mean the standard treble instrument rather than other instruments of the family, such as the "cor anglais" (English horn) or the oboe "d'amore". - Metropolitan Opera Live in HD (also known as The Met: Live in HD) is a series of live opera performances transmitted in high-definition video via satellite from the Metropolitan Opera in New York City to select venues, primarily movie theaters, in the United States and other parts of the world.

The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek ("mousike"; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound." What is the relationship between 'ariana ghez' and 'oboe'?
