The core premise is deceptively simple:
Here is a practical exercise known as a "Harris Cycle" that was transcribed by his student, bassist David Friesen:
In the 1970s, frustrated by the limitations of diatonic (seven-note) scale theory, Harris wrote a book. It wasn't a songbook; it was a philosophy. He posited that most improvising musicians are trapped inside "the box"—the major scale and its modes. The was his explosive escape hatch. eddie harris intervallistic concept pdf
For decades, the name Eddie Harris has resonated far beyond the cool, smoky confines of the traditional jazz club. Known primarily for his soul-jazz anthem Freedom Jazz Dance and his pioneering work on the electric saxophone and Varitone device, Harris was more than just a performer. He was a mathematical mystic of melody. Among serious improvisers, music theorists, and obsessive collectors, one term carries an almost legendary, cryptic weight: The Eddie Harris Intervallistic Concept.
But perhaps this is fitting. Eddie Harris was an inventor who believed music lived in the mind and the fingers, not just the page. While you search for the file, build your own intervals. Cycle your own thirds. You might just discover that the PDF you were looking for was the pattern of intervals you generated yourself. The core premise is deceptively simple: Here is
Don't let the lack of a PDF stop you. Take a C Major scale. Remove the 4th and 7th. Play in leaps of 4ths only. Chromatically alter one note per bar. Congratulations—you have just entered the Intervallistic Universe. Eddie would approve.
However, Harris’s secret was that he swung the mathematics. He used the concept as a springboard , not a cage. He would play a cycle for two bars, then resolve it into a blues lick. The was his explosive escape hatch
Start on a note (C). Ascend by a Major 3rd (to E). Ascend by a Major 3rd from E (to G#/Ab). Ascend by a Major 3rd from Ab (to C). You have landed back on C after 3 leaps. That is a closed cycle .
