It’s hot … as in Sahara desert hot, except with humidity that makes it feel like Satan’s armpit. But if it’s going to be Sahara hot, we may as well spend A Night in Tunisia …

This jazz standard was written by Dizzy Gillespie in 1941, and quickly became a well known standard. The exotic, sweltering sound is woven by a funky bassline and a repeating chord progression which uses a jazz “trick” of substituting an expected chord with the tonality a tritone away (in this case, we want to hear A, we get Eb instead – this interval A-Eb is known as a tritone, or the “devil’s interval”). Also, an Eb chord in a D minor piece implies a Phrygian mode, which is a scale we commonly associate with the “exotic” lands of the African Mediterranean or middle east. So, the Eb chord is doing double duty: exoticism AND devilish trick. And we like it.
