Djent is a subgenre of progressive metal. Its distinctive sound is a high-gain, distorted, palm-muted, low-pitch guitar sound. The name "djent" comes from the genre's characteristic sound, it is an onomatopeia of the sound.
Djent as a style is characterized by progressive, rhythmic, and technical complexity accompanied by a dense layer of polyphonic groove. An example djent song features heavily distorted, palm-muted guitar chords, syncopated riffs, and polymeters alongside virtuoso soloing.
Another common feature is the use of extended range seven-string, eight-string, and nine-string guitars. There has been extreme uses of numbers of strings in a guitar. Some of the most popular djent metal bands such as Periphery, Vildhjarta, Veil of Maya, Tesseract and Animals as Leaders were all founded in early 2000s, so it is possible to say that Djent is a newer subgenre than thrash and heavy metal.
Metal keeps evolving day by day, forming many different genres with many different sounds. It is nice to see that metal is still active today.
