I consider it a masterpiece in the fullest sense of the word: one of those rare compositions which seems to reflect most strongly in itself the musical tendencies of a whole generation.”

Location recording, remote broadcasts, image intensifiers, contrast compression, diplexed audio, and live subtitling are just some of the other media technologies pioneered for opera. 3-D and interactivity have already found their way into opera. And an opera project has already used the technical facilities of the European Center for Nuclear Research, home of the giant supercollider featured in Angels & Demons. Yes, opera.

Operatic singing, which was developed in Europe during the 17th century, places far greater vocal demands on an opera singer than on any other type of singing. Opera singers rarely use microphones, and therefore must develop their voices to make a sound that will project and be heard above an orchestra and be heard throughout a large theatre.
After years of practice and study, an opera singer learns to use his or her body as an amplification device. By controlling the muscles of the diaphragm (a muscle beneath the lungs and above the stomach) the singer can regulate the amount of breath used. The diaphragm expands and contracts, regulating the air that passes through the vocal cords, which, in turn, causes them to vibrate. The speed at which the cords vibrate determines the pitch. As the sound passes through the mouth, it resonates in the upper chest cavities and the sinus cavities of the face and head. These cavities act as small echo chambers and help amplify the sound. The shape of the mouth and the placement of the tongue near the lips contribute to the tone and sound of the words.
Many singers begin their operatic training in university. Opera students study singing, music history, composition and vocal pedagogy (voice teaching). In addition to music classes, they study diction and often study at least one foreign language. After university, singers begin to work in the professional world. Their first roles are usually small parts, but if they continue to study and train, they may move on to the bigger principal roles.
Professional singers develop a number of roles in their repertoire. Since the principal artists are required to have their parts memorized before rehearsals begin, singers must prepare well in advance of each contract. Singers have voice teachers who help them refine their singing techniques and many will also have an acting coach. Even a well established singer will have a vocal coach to teach singing and acting techniques for specific roles.
Each person’s vocal tract is constructed differently. The roles that a singer performs are dependent mostly upon their vocal range, but within the vocal ranges, there are many colours and weights of voice that further determine which roles he or she can sing safely. Vocal colour refers to the richness of the sound and vocal weight refers to how powerful a voice sounds.
After the role has been studied intensely and the singer is hired to perform, they arrive at the opera company for the rehearsals. This time is spent refining the music with the conductor and staging the action with the stage director. Each director has a different idea of how the character should be played, and each conductor has a different idea of how the character should sound, therefore the singer must modify his or her techniques to reach the desired result.
Physical health is a major priority to a singer. Contrary to popular belief not all opera singers are overweight. Conventional wisdom used to state that excessive weight gave added volume and richness to the voice however, in recent years, people have discovered that physical fitness can give similar benefits to a voice. Plus, the overall health benefits of being in shape overshadow any loss of vocal power. Most singers, like professional athletes try to avoid such substances as tobacco, alcohol and caffeine.
