Likya Dede

The little girl is out of sleep. She asks Likya Dede to tell her a story that she has not heard before. Likya Dede accepts with one condition: At the end of the story she must find the name of the story and the characters. She happily accepts the challenge and Likya Dede beings his story about a man and a woman.


Through out the story he talks about:

How they exist,
How they become lovers,

How they become one,
How they become extinguish,

How they become permanent.


The piece is symbolizing the rite of passage for the little girl. At the end of the story, she will find the name of the characters.


The source of the Likya Dede stories are based on Anatolia. His main aim is to present the wholeness of the cultures which had been shaped in thousands of years, by many civilizations.

Likya Dede is a modern story composed for dance, narrators, symphony orchestra and ethnic instruments. Little girl and Likya Dede acts during twelve consecutive movements. A monolog of Likya Dede pursues the dialogue and music continues.

Tritonet, a musical abacus, provides an innovative way of teaching harmony. It allows a practical and easy to comprehend methodology, making learning music theory more accessible. Based on the Circle of Fifths, its original design integrates a broad spectrum of possibilities for music theory education, both traditional and new. Tritonet has an interconnection with geometry, mathematics, and astronomy, which was an idea envisaged in the 5th century to be the foundation of academia, a useful tool to reconnect Music with Quadrivium.

Following my research for Tritonet, I wrote a textbook called “The Tritonet Approach to Music Theory”.


In addition to the textbook, I also designed a set of Max/MSP patches to provide a harmony toolset for the digital music production industry. It enables users by applying "Dynamic Midi Mapping" to create chords with proper voice leading, to change harmony automatically, to play the keyboard and the Midi pads effortlessly, to extract the harmonic structure of one musical piece, and to apply it to another on Ableton Live. 


My ultimate goal in my life is to develop a novel tonal domain signal analysis instrument, which will complement the time and frequency signal analysis that is currently the standard around the world. This will allow researchers to analyze harmonic structures in a time-space domain.
