This is a jazz tune that is really more or a blues tune. The piano left hand is almost entirely made up of tritones. Hence the title.
I’m a bit fixated on the tritone: two notes which are three tones apart in pitch. An interval of three tones, that is. For centuries known as “the Devil’s interval”, or “the taboo interval”. It features heavily in blues music. Perhaps not coincidently known as the Devils music.
Have a listen, please, if you like:
I attached this tune to my story Meet Mister Mitosis, in the place called Hugo’s Ballpoint.
