During the twentieth century, the concept of "Pop Music" emerged, and although popular music has always existed in one shape or another, this area of sound recordings meant that songs could become "hits" by reaching many people at once. Early on, many instruments did not translate well to tape. However, the trumpet proved to be an exception, and quickly became a standout favorite, thanks to its clear focused sound. Virtuosos like Louis Armstrong brought the trumpet to the forefront of popular music during the 1930's, and its popularity continued for decades, from Dizzy Gillespie to Miles Davis.
