Southeast Just Intonation Center (SEJIC)

New Musical Instruments
Harmonic Series Music
Plans for an International Microtonal Arts Center


The SEJIC was the first activity of the World Harmony Project.

It's mission was to enhance the development of musical expression, by means of the implementation of Harmonic Series based Just Intonation, Polyrhythmic structures, and Timbral Tonality.

It began with a Music Studio, directed by and containing the musical instruments 
(acoustic and electronic)
of WHP founder, 
Denny Genovese.

These instruments were specially designed to be played in the Extended Just Intonation scale of 65 pitches per frequency duple (octave), developed by Denny Genovese while writing his New College Thesis, The natural Harmonic Series as a practical approach to Just Intonation .

The first part of the strategy was to improvise with the new scale to learn it's musical properties, then to compose music using these sounds, according to the properties discovered.

The second stage was to teach an ensemble of musicians to play the new compositions with the new instruments in the new tuning.

The third stage was to produce performances of the ensemble, test for audience response, refine the music and performance according to the feedback, and finally to record the music and make it available to interested listeners.

The name of the performing group was 
 Denny Genovese's Exotic Music Ensemble.

Four performances per year were co-sponsored by the City of Gainesville, Florida's Dept. of Cultural Affairs, in  The Historic Thomas Center from 1992 to 1998.

The Album, produced on cassette in 1994 and on CD in 1998 is called New Music - Ancient Principles.

Electronic Studio

The SEJIC housed an Electronic Music studio, as well. It included historic analog instruments and tape recorders, as well as computer based digital composition, synthesis and recording facilities.

Computers and software for producing music in Just Intonation were provided on the PC, Mac, Amiga, Atari-ST, Apple-II, Comadore-64 and TI-99 platforms.

In addition to the EME, the SEJIC studio was made available to other musicians and composers who wished to learn about or utilize the Natural Harmonic Series and Just Intonation.

Classes, Seminars, private Lessons and Residencies were conducted there as well.

The SEJIC served as the focal point of what evolved into the 1st World Harmony Center.

An additional set of instruments for Harmonic Series Music were developed at the SEJIC by Jeff Bunting during his residency in 1996.

An extensive Music Library and archive of scores and recordings of music in Just Intonation was maintained at the studio.

The SEJIC was directed by Denny Genovese from 1992 until 1998.

It was directed by Pat Pagano from 1998 to 2003.

L. to R.: Thierry Mingione, Darren Burgess, Pat Pagano, Bob Benchic

It was inactive from 2003 until 2007.

In 2007, it was revived under the directorship of Joshua Lederman, who created a series of radio programs around jam sessions with various Gainesville, Florida musicians  using Denny's instruments.


As of January 2012, everything is in storage, awaiting relocation to Urbana, Illinois in the Spring of 2013.
