"Now, the instrumentation in the jazz band and the jazz dance band has gone through many evolutions. For instance, in the 'twenties the tradition was two or three saxophones"

This quote by Gerry Mulligan speaks with the evolution of jazz songs and dancing bands over the years. In the 1920s, the conventional instrumentation for a jazz band or dance band was 2 or three saxophones. This was the requirement for the time, and it was the audio that was most popular. However, as time went on, the instrumentation of jazz bands as well as dancing bands started to develop. New tools were added, such as heralds, trombones, as well as drums, as well as the sound of jazz began to alter. As jazz songs and dance bands continued to advance, so did the instrumentation. Various instruments were added, and also the sound of jazz started to come to be more complicated and also varied. This development of jazz songs and dancing bands has actually remained to now, and it is a testament to the imagination as well as innovation of jazz artists.
