Almost all music critics divide contemporary musical styles into three main categories: rock, pop, and rap. Each of them is divided into many sub-styles.
Popular music
Pop is popular music. An extremely broad term that has encompassed many genres and subgenres. It includes styles such as disco (dance music with an abundance of effects, a clearly defined rhythm section, the addition of wind and string instruments), trance (electronic music with an abundance of cosmic melodies), house (completely electronic music, the only instrument of which is a synthesizer, repetitive musical phrases are a characteristic feature), techno (city music, metallic sound, cold vocals, a huge number of effects), funk (a dance genre with leading drummers, out of tune and low melody). This musical direction is especially popular among domestic musicians.
Rock music
Rock as a genre is rooted in the old, foreign, black blues, which appeared in America in the twenties of the twentieth century. Any blues consists of twelve measures or sections of the composition, each of the measures consists of several notes, with the emphasis always on the first. The traditional instrumental set of blues music includes bass or contrabass, drums, horns, keyboards and, of course, a guitar. Rock grew out of "guitar" blues, which does not have as many winds and keyboards as traditional.
Rock and roll became the music of young people in the fifties of the twentieth century, it was a simplified variation on the blues. Over time, rock grew out of it, which became an art under the influence of the Beatles.
The Beatles actually became the founders of half of the rock subgenres.
In fact, rock is blues, but with a different meaning. Rock is, first of all, protest music. There are many subgenres in rock. For example, hard rock is a style with a heavy, harsh sound, the rhythm section occupies a dominant position in this style, it is in hard rock that you can hear the most interesting, "free" vocals. Pop-rock is called soft, rhythmic music with light arrangements, designed for a wide audience. Folk-rock is a popular trend now, trying to combine rock and folk music. Psychedelic rock is unconventional, complex music with an abundance of effects, usually having a serious impact on the listener. Heavy metal - harsh, heavy, inharmonious music, it is very far from the usual standards.
Very often in the modern world there is a mixture of genres, when it is quite difficult to determine exactly which style a particular composition belongs to.
Rap music
Rap most likely originated from the reggae dance style in Jamaica. There is a lot in common between these styles - uneven rhythm, repetitive musical fragments, complex work of the rhythm section. In fact, rap lacks vocals as such. The text is pronounced here in a recitative. The main instruments are bass and drums, and additional effects are often used.
