Groovin’ High was written by the great trumpeter Dizzy Gillespie in 1945. The chord changes are based off of Paul Whiteman’s composition Whispering. Be sure to learn the four bar intro from the original recording! You’ll also notice extra bars at the end of the form from the original arrangement leading to a key change (during the head). This is sometimes played, but most often in a jam session situation is ignored. This tune is most commonly played in Eb major.
