[Denny Genovese] Pioneers of Natural Harmonic Music ]

New Musical Instruments
Harmonic Series Music
Proposals for the new World Harmony Center


While the World Harmony Project was incorporated in 1992, it's musical roots go back several decades before. The following entries give credit to some of the people who have been involved.

World Harmony Project's Exotic Music Ensemble 1994

Back row: Joshua Lederman, Buddy Young, Buzz Kimball, Denny Genovese, Wade Hines, Keton. Bob Nuefeld. Front: Karen Boon von Ochssee, Dawn Delo

This group fulfilled WHP's first mission: to discover the musical properties of the Natural Harmonic Series as a scale, compose and perform music based on these discoveries and to record it for posterity. Elements of this scale formed the roots of  the music of many of the worlds cultures, so the stylistic theme of the ensemble was the  musical traditions from  around the world. EME took this a step further however, by composing new music, based on an expanded version of the scale, in the spirit of unifying the roots of the various nations in a planetary cultural effort. EME was a pioneer effort in the cause of World Music.

Harry Partch

Harry Partch was the musical pioneer who returned Just Intonation to Western music after 3 centuries of forgetfulness. In the process, he introduced Western Music to three additional pitch classes, based on the addition of the seventh, ninth and eleventh harmonics to the tonal pallet. This made possible the expansion of the triad (harmonics 4, 5 and 6) as a basic harmonic unit to the hexad (Harmonics 4, 5, 6, 7, 9, 11) providing 6 tonal pivot points in each chord.

 Partch also implemented the mathematical inversion of the Harmonic Series (Subharmonic Series) in his music and the resulting network of scales formed a 6x6 matrix of tonalities. Arranged in sequence by frequency, the pitches of the matrix, along with those of related secondary tonalities form a 43 tone scale that increases the melodic and harmonic resources of  Tonality many fold.

To implement his music, Partch built an orchestra of instruments especially designed to play his expanded musical scale, and used odd numbered rhythmic meters and polyrhythms as well. Much of his music was vocal and presented in a theatrical context, portraying mythical themes.


Harry Partch with Peter Coraggio - 1971

Peter Coraggio,  was a pioneer of Electronic Music in the 1960's and 1970's. A student of Vladimir Ussachevsky at the Colombia/Princeton Electronic Music Studio, he brought Electronic Music to Hawaii in 1971 when he began his career as professor of music at the University of Hawaii. In that same year, he brought Harry Partch to Honolulu for a series of lectures and performances. Subsequently, one of Peter's students, Denny Genovese learned of the Harmonic Series and Just Intonation.

The instrument they are playing in this photo is the ARP 2500 modular analog synthesizer. This Instrument formed the core of the Analog studio of the Hawaii Electronic Music Group and later the Southeast Just Intonation Center. Some of it's components continue today in the custom Theremin, played by Denny Genovese.

Ivor Darreg  was a prolific and visionary Writer, Composer, Music Theorist, Instrument Designer and Networker whose tireless efforts helped to develop the theory and practice of Microtonal Music, including Just Intonation and the Harmonic Series, in the 20th century. He was a mentor to Denny Genovese, as well as a number of others, and an early supporter of World Harmony Project.

Erv Wilson and Denny Genovese - 2001

Erv Wilson is the great guru of microtonal music theory in the United States. This picture was taken at his home in Los Angeles in 2001.

Joe Monzo, Denny Genovese and Jonathan Glasier - 1998

Jonathan Glasier grew up in San Diego with Harry Partch as a frequent house guest. His father, John Glasier senior, was a great cellist and violist, who could improvise in many different microtonal scale systems, and was one of Partch's most constant friends and supporters. Jonathan was a member of Partch's ensemble, and personally cared for the composer in his last years of failing health.

In addition to his life long career as a microtonal musician and instrument builder, Jonathan self published the historic magazineInterval - a microtonal newsletter throughout the late 1970's and most of the 1980's. As a child, he developed a form of Harmonic Singing  and taught this method to Harry Partch, Jonathan Goldman and others. He is the co-proprietor with his wife Elizabeth, of the Sonic Arts Gallery in San Diego.

Joe Monzo is a composer, musician, author, computer programmer and teacher specializing in Just Intonation. His method of organizing tonal materials into multi dimensional lattice configurations provides clear pathways for tonal explorations.

Denny Genovese with Dr. Easley Blackwood - Chicago 1985

Dr. Easley Blackwood, of the University of Chicago is an important author, composer, performer and teacher of microtonal music . In 1985, he released an album of 12 compositions, one in each of the equal temperaments between 13 and 24 pitches per duple (octave). Each composition was a masterpiece that clearly exemplified the properties of the scale it was created with. For this reason, he is best known as a proponent of equal tempered scales. However, he was an important theorist of just Intonation as well. Denny Genovese interviewed him that summer for an article about the album which appeared in Interval Magazine, and returned many times after that for tutorials in Just intonation.

Easley Blackwood with the Motorola Scalatron

The Motorola Scalatron was an early polyphonic synthesizer that was capable of being tuned in any configuration of up to 31 pitches per duple (octave). Tunings were stored in memory banks that the player could quickly switch between with radio style buttons.

Dean Drummond and Denny Genovese - NJ 2001

Dean Drummond was a member of the Harry Partch Ensemble, is the heir of Harry Partch's instruments, following their era with Danlee Mitchell, and is the founder of the Partch Studies department at Montclair University in New Jersey.

Denny Genovese, Barbara Hero and Robert Faulkrod at the SEJIC studio - Gainesville, FL 1997

Barbara Hero is a scientist, author, lecturer and music therapist who has done extensive research on the applications of the Pythagorean Lambdoma (the frequency matrix that forms the basis of Harry Partch's Tonality Diamond), in various bands of the electromagnetic spectrum. 

Robert Faulkrod is a poet and electrical engineer, who built a keyboard to play the Lambdoma scale and simultaneously project the combinational waveforms in a laser light show. When they produced a limited number of these keyboards for sale, Denny Genovese designed and facilitated a collaboration with British programmer, Robert Walker to create a component of his MIDI program, Fractal Tune Smithy that allows musicians to play Lambdoma music with their PC computers.

Barbara Hero, Dick Lord, Robert Faulkrod, Linda Joy Lewis

Wells, Maine 2002

Dick Lord created an alternate operating system for the Ensoniq Mirage, a historic sampling synthesizer, in the 1980's. This operating system facilitated the use of microtonal scales, including Just Intonation. Linda Joy Lewis, a gourmet vegan chef, served as Hospitality Coordinator and has been a board member and devoted supporter of World Harmony Project from it's inception in 1992.

Mark Rankin produced interchangeable fret board kits for guitars, and other stringed instruments for many years.
