Jump Time is a Sy Oliver chart written for the Tommy Dorsey Orchestra, and is a Trombone feature. This version was transcribed from his November 19, 1940 session live to air from the Hollywood Palladium, which was also his 35th birthday. Although not one of Dorsey's better known titles, Jump Time is a great chart for the swing dance crowds and it grooves along from start to finish. After the intro Piano solo the Brass are expected to sing the invitation for the Trombone soloist to start playing. However, we have also cross-cued this unison line onto the Saxes, in case your Brass players are not in a singing mood. There are a couple of ad-lib solo spots for Trumpet 2 and Tenor 1, and Alto 1 & Tenor 2 have brief Clarinet doubles for the last chorus.
