In this video I am playing the sequence of 'Cherokee' using chains of Negative Harmony 7th chords, polarised towards the important cycle of fifths junctures in the regular sequence. The 'backdoor' IVm-bVII can also be expressed with Negative Harmony ideas, as can the tritone versions of both progressions. Following these chains and loops, strings of minor plagal moves, gives a me wonderful sense of falling backwards through space. There is a feeling of navigating a parachute drop gently on to the cadence point, rather than the sharp, tension-release of regular jazz harmony. Using tritone substitutions of the Negative Harmony minor 6th chord movement gives a rising semitone sequence (D7-G7-C7 = Bbm-Fm-Cm or D7-Db7-C7 = Bbm-Bm-Cm) another marvellous, liberating feeling for a jazz musician who has been tied into the cycle of fifths for thirty years. A 'backdoor' version can also be mixed in: (Dm-G7-C = Dm-Ebm-Bbm-Fm-C) therefore (Fm7-Bb7-C = Fm-F#m-C#m-G#m-C).
Here is a transcription of what I play in the video. The pulse comes and goes, giving it a sort of fantasia feel. I was short of breath, as the temperature in Ruislip that day in July 2018 was about 33ºC and Lockett Towers was not blessed with air-conditioning!
