“Good Bait” was written by Tadd Dameron. This is among one of his first compositions that he wrote for Dizzy Gillespie’s band which he was a part of in the 40′s. However it was made famous by Count Basie’s Orchestra. You can think of this song as similar to the A sections of a rhythm changes tune.
This tune settles into two key centers, Bb major and Eb major.
