Modern time
From about 1900 onwards is called the "modern period". Many 20th century composers wanted to compose music that sounded different from the Classical and Romantic music. Modern composers searched for new ideas, such as using new instruments, different forms, different sounds, or different harmonies.

The composer Arnold Schoenberg (1874–1951) wrote pieces which were atonal (meaning that they did not sound as if they were in any clear musical key). Later, Schoenberg invented a new system for writing music called twelve-tone system. Music written with the twelve-tone system sounds strange to some, but is mathematical in nature, often making sense only after careful study. Pure twelve-tone music was popular among academics in the fifties and sixties, but some composers such as Benjamin Britten use it today, when it is necessary to get a certain feel.

One of the most important 20th-century composers, Igor Stravinsky (1882–1971), wrote music with very complicated (difficult) chords (groups of notes that are played together) and rhythms. Some composers thought music was getting too complicated and so they wrote Minimalist pieces which use very simple ideas. In the 1950s and 1960s, composers such as Karlheinz Stockhausen experimented with electronic music, using electronic circuits, amplifiers and loudspeakers. In the 1970s, composers began using electronic synthesizers and musical instruments from rock and roll music, such as the electric guitar. They used these new instruments to make new sounds.

Composers writing in the 1990s and the 2000s, such as John Adams (born 1947) and James MacMillan (born 1959) often use a mixture of all these ideas, but they like to write tonal music with easy tunes as well.

Electronic music
Music can be produced electronically. This is most commonly done by computers, keyboards, electric guitars and disk tables. They can mimic traditional instruments, and also produce very different sounds. 21st-century electronic music is commonly made with computer programs and hardware mixers.

Jazz
Jazz is a type of music that was invented around 1900 in New Orleans in the south of the USA. There were many black musicians living there who played a style of music called blues music. Blues music was influenced by African music (because the black people in the United States had come to the United States as slaves. They were taken from Africa by force). Blues music was a music that was played by singing, using the harmonica, or the acoustic guitar. Many blues songs had sad lyrics about sad emotions (feelings) or sad experiences, such as losing a job, a family member dying, or having to go to jail (prison).

Jazz music mixed together blues music with European music. Some black composers such as Scott Joplin were writing music called ragtime, which had a very different rhythm from standard European music, but used notes that were similar to some European music. Ragtime was a big influence on early jazz, called Dixieland jazz. Jazz musicians used instruments such as the trumpet, saxophone, and clarinet were used for the tunes (melodies), drums for percussion and plucked double bass, piano, banjo and guitar for the background rhythm (rhythmic section). Jazz is usually improvised: the players make up (invent) the music as they play. Even though jazz musicians are making up the music, jazz music still has rules; the musicians play a series of chords (groups of notes) in order.

Jazz music has a swinging rhythm. The word "swing" is hard to explain. For a rhythm to be a "swinging rhythm" it has to feel natural and relaxed. Swing rhythm is not even like a march. There is a long-short feel instead of a same-same feel. A "swinging rhythm" also gets the people who are listening excited, because they like the sound of it. Some people say that a "swinging rhythm" happens when all the jazz musicians start to feel the same pulse and energy from the song. If a jazz band plays very well together, people will say "that is a swinging jazz band" or "that band really swings well."

Jazz influenced other types of music like the Western art music from the 1920s and 1930s. Art music composers such as George Gershwin wrote music that was influenced by jazz. Jazz music influenced pop music songs. In the 1930s and 1940s, many pop music songs began using chords or melodies from jazz songs. One of the best known jazz musicians was Louis Armstrong (1900–1971).
