          and scientific discoveries
        
          Greatest influence on creativity and production 
          Not only in a literal, physical way but psychologically and
          philosophically
        
- The speed and accessibility of all aspects of communication has dramatically
        increased
        - Developments have resulted in a world that is more informed
        about events elsewhere
        
          Helps to develop similarities and
            uniformity of taste 
          Extensive effect on concert and popular music
          
            Latin American dances 
            African American call-and-response settings 
            Microtonal melodies
            of Asian music
          
- The recording and broadcasting
        industries have developed to a point where:
          Long musical works can be recorded without interruptions 
          Recordings of any and all types of music are readily available
          
          Music is accessible anywhere (portable)
        
- Electronic instruments are more
        accessible
          New avenues of timbre are
          available to explore 
          Pitch manipulation offers new
          options to composers 
          Rhythmic complexity, beyond human
          capacity, is possible 
          Computer technology and MIDI
          (Musical Instrument Digital Interface)
          
            Offers incredible ease of composition and orchestration
          
- Technology has led to the experimentation and development of multimedia works
          Especially in the area of commercial production (MTV)
        
- The general noise level of the environment is much higher than
        in previous eras
          Certain types of music (rock/popular music) incorporate a
          higher decibel level
          
        
- The recording industry has led
        composers to compose with recording in mind
          This leads to the manipulation of the
            recording devices that control and change
          
            the original sound, as part of the compositional process
          
Composers as well as listeners expect
            perfection
            Which in turn raises the performance standard for performers
          
- The convenience of technically flawless recordings has had a diverse effect on live performance
        - Following World War II, Communist bloc
          countries
        
          (Poland, Czechoslovakia, Hungary, Bulgaria, Rumania, and East
          Germany)
          
            were cut off from the leading musical
              trends
          
The death of Stalin removed some restrictions
          The dissolution of the USSR and the Soviet bloc will
          inevitably effect
          
            future musical development
          
- The dissolution of overseas empires has allowed the
        development
          and dissemination of various indigenous musical cultures
          
            Has sparked a new interest in multi-cultural
              music
            
            New concepts and instruments for composers to explore 
            New areas of music education (ethnomusicology)
          
- An emphasis on music education has brought about a new type of
        patronage
          Schools, colleges, and universities are employing 
          Artists, composers, etc. as faculty
        
        II.  Function of Music 
      
        - Many colleges and universities
        have resources in teaching and performance
        
          They have become fertile ground for experimental and avant-garde
          composers 
          Some of the most elaborate resources
            for electronic music are to be found in
          
        
- In Europe, broadcasting studios
        have also been in the vanguard of this movement
        - Special festivals and concert series
        have been organized for the purpose of
        
          presenting works of contemporary composers, especially the avant-garde 
          and non-Western music
        
- There have been dramatic increases in the number of cities
        that have developed
          opera companies
          
            The U.S. produces mostly traditional works, some
            contemporary 
            Europe produces more contemporary works than U.S.
          
- Ballet has achieved a position
        of high importance in Europe and North America
          Modern dance is being
          incorporated with traditional
        
- European television and Public
          Television in the U.S. broadcast numerous concerts
          and musical events each year that include contemporary works
          
            These are generally adaptations of stage or concert
            performances
          
        III.  Style and Performance Practice 
      
      
        IV.  Music for Voices 
      
        The vocal music of the 20th century has been criticized for its
        instrumental character.
        
          Successions of intervals that could be easily negotiated by
          instruments, 
          often outside any tonal scheme, are demanded of singers.
        
In solo and choral works, the voice is often freed from verbal considerations.
          Shouts, screams, and grunts are often used
        
A new school of vocal production has evolved around "extended vocal techniques"
        More recently, there has been a noticeable
          return to
        
      
          
        - Single-Movement Forms
        
          Art songs
          
            Individual and cyclic settings
            continue to be composed 
            Some composers wed the voice to a varied array of
            traditional
            
              and electronic instruments
            
Choral works
            All the traditional and experimental
              forms 
            Writing for church and schools
            has occupied some composers' time 
            Few of the large religious works are appropriate for
            liturgical services 
            Liturgical music often uses a style that might be called neo-Baroque
            
              a contrapuntal style with 20th-century idioms
            
          - Composite Forms 
        
          Opera and Musical
          Theatre
          
            Opera continues to examine historic ("The
Rake's
Progress,"
            Stravinsky)
            
              and current ("Nixon in
              China," Adams) themes
            
In the U.S. there has been a growing need
              for chamber operas
            Many works have multimedia elements
            
            Musical Theatre flourished in the 1950s and 1960s in the
            U.S. 
            Resurgence of vitality in England in the 1970s and 1980s 
            The rather artificial distinction between opera and the
            musical play
            
              has become eroded 
              ("Porgy and Bess," Gershwin;
              "Sweeney Todd," Sondheim)
