For example, Fox Trots can be played from 32 to 38 measures per minute. When playing their songs, these orchestras generally set up their arrangements with the dancers' needs in mind . The music is often provided by a deejay or small bands. The music is arranged to enhance that ability. If by chance people find it a fun song to dance to that is a plus but no attention has been paid to what might make it easier for a dancer to follow the rhythm.
Small bands play their own arrangements of classic favorites or current pop tunes.
Seldom are the musicians dancers so again we have the focus on the musicians' performance ability on their particular instrument. They must play so that they can sound their best. Often if musicians are very proficient, they enjoy adding the equivalent of a dancer's syncopations to their music. This ability is recognized and very much appreciated by other musicians. Unfortunately it often gets in the way of an inexperienced dancer who is struggling to hear the basic rhythm.
