Music would forever be changed by the developments of the 20th and 21st centuries and through the invention of the internet, music has become a global median for all languages.
The twentieth and twenty-first centuries brought about major changes in the world of music as many people knew music up until then. For centuries before, music was mainly made up of instrumental music from stringed and wind instruments with the exception of Operas. With advancements in technology and culture many new genres of music developed along with an increased involvement of women in music. There was also an increased presence of vocals being used in the creation of music during the twentieth and twenty-first centuries. This had much to do with the change in culture as well as the advancements in technology and increased the variety of venues musical performers could play in. The new electronic instruments also developed during this time were a strong contributor in the large increase of different types of music created.
A large number of new musical genres were created during the 20th and 21st centuries. These include but are not limited to Jazz, Rock and Roll, Country, Blues, Folk, Pop, R&B, Rap, and Electronic. Many of these new genres are derivatives of earlier forms of music and many have sub genres underneath the main ones. This huge influx of new musical genres was due in part to the large numbers of immigrants entering the United States and the melding of different cultures into one another. The melding of cultures helped bring new ideas and some new musical inventions such as the electric guitar, bass guitar, drum kit, synthesizer, sampler, and keyboards to create fresh new melodies. It was through these freedoms and experimentation that musicians were able to express ideas that would change the way the world would view and hear music forever.
