A rhythmic musical style

The composition of American black folk songs is very complicated. It not only retains the tradition of African music, but also is gradually influenced by European music, resulting in many African-American music forms, such as blues, ragtime, soul music, gospel songs and so on. Most of them show the unfortunate life, sadness and desire for happiness of black people. Among them, Bruce and Lagenheim have the most far-reaching influence, and some of their artistic features are still preserved in jazz.

Blues music is also called "blues" or "sad music". /kloc-in the 0 th and 7 th centuries, a large number of African blacks were sold to the United States as slaves. These slaves were influenced by the earliest forms of music-labor songs and field songs, which were strongly influenced by the music familiar to African blacks. Religious music is one of the important media of early musical contact between blacks and whites in the southern United States, which influenced blacks musically and formed black hymns. The appearance and development of these three kinds of music provided the premise for the birth of Bruce.

In the second half of the19th century, the style of black music developed rapidly, and at the same time, it was influenced by African music and traditional music brought by American whites from Europe, forming a unique style of black folk songs and blues music. At the same time, the popularity of guitar is also one of the factors that have a far-reaching impact on the development of Bruce in music. Before that, the most popular musical instruments in black hands were violin and banjo. However, the guitar is the most suitable instrument to accompany Bruce. This is because the guitar almost has the characteristics of human voice, and the player can use the sliding string to make the notes out of tune and make the guitar make people cry.

Blues has always been a kind of improvisational music-that is, players compose melodies while playing. Early blues singers also wrote their own lyrics and played the guitar while playing. Therefore, blues lyric songs often adopt the form of repeating a single melody and adding a new melody at the end of the song. Some characteristics of blues reflect the influence of African music. Every vocal melody is followed by a short guitar instrumental music, which is obviously a common form of response rotation in African music. Compared with European style, the range of blues singers is closer to African style; Emphasis on repetition, in order to strengthen motivation and excitement, is a way of playing in Africa. Nevertheless, blues is not an African music, but a very independent music style, which is strongly influenced by Africa, Europe and the United States.

Blues songs use three chords (I, IV and V) to connect in a certain order or module. Generally speaking, a bar (4 beats) is matched with a chord. Usually a piece of music is twelve bars and three lines of melody, each line accounting for four bars; But singers often sing only two bars per line, and the last two bars are accompanied by guitar. The usual structures are: I-I-I-I, VI-VI-I-I, V-IV-I-V. Guitar plays a very important role in blues music, weaving structure and enriching melody, but often a good guitarist doesn't show off his skills, but just sings the melody in his heart properly with his guitar, or laughs or cries.

Blues is produced to express the singer's personal feelings, which provides musicians with an opportunity to express themselves; Their love, their hate, their attitude towards work and so on. The famous blues singer Brown Marks once said, "I never use my imagination to write music. The blues is not a dream, but a reality. " Bruce itself is a state of mind, music of ordinary people, and music from life. And its content includes a lot, which is the most true reflection; Resistance to injustice, longing for beauty and love, frustration after setbacks, emotional catharsis; At the same time, humor, self-deprecation, and sometimes even a tearful smile.

Ragtime music is a kind of piano music. This music style was the most popular in the 20th century10s and 20s, but it originated from a "mob" dance performed by black bard. Tracing back to the source, this performance is that white actors blacken their faces with charcoal to make fun of black people. But after the liberation of slaves, they also formed a wandering troupe to compete with whites in singing and dancing. This kind of music is familiar to people in the form of mob dance or piano music that entertain guests in salons, casinos and snack bars. Ragtime music is the closest to European style in origin, at least with traces of African music.
