2017 in a nutshell

How was your year? It’s always exciting to look forward to a new year, making and setting up a fresh plan with a full of motivation! At the same time, it is very important to think about the past year, what are the achievements, and what I have missed. 

This post is about my memorable activities of the year 2017. I selected 4 activities:

  1. DELETION at International Film Festival Rotterdam

    ‘DELETION’ is a short film made by Esther Urlus, who I met two years ago for Light Leak project with Filmwektplaats. She’s a special filmmaker in The Netherlands, who create DIY 16mm experimental films. The length of the film is around 10 minutes, completely abstract, accordingly there was enough space for me to explore with sounds. The film is about a murder scene -accordingly, a horror movie!- but you don’t see or recognize anything through the screen. The story is behind the complete abstract scenes. The soundtrack therefore has a big role for audience to follow the story line.
    Thankfully this film was nominated at Tiger Competition for Short Films 2017 at IFFR, which gave me a totally new experience to attend the festival, sitting there with other amazing filmmakers and actors/actresses. Even though the film wasn’t the winner, it was for me a great achievement. I hope to have more opportunities working on films. I quite like it.

  2. Azimuth #3

    ‘Azimuth’ is a foundation that their multichannel system offers composers/artists to create spatial music/arts with the system. Azimuth #3 was my first experience with it. The piece I wrote is ‘Punky-Pulse-Pool’ for 32 channels.
    The materials were created from a short theme, a gesture using pulse oscillator, and as in variations on a theme, it was developed, manipulated, and re-synthesized into diverse forms. Then instead of presenting them one after another, they were massively and randomly thrown in time and in space. As if one freely plays a puzzle with multiple different blocks, the layered and squeezed sound materials are then sculpted and re-organized not only musically but also spatially. In that way new relationships between sound events are revealed, and the allied, survived sound parts are newly developed from there with a found connectivity.
    I wrote the blog post about my experience in more detail.


  3. ‘Bamboos’ for Bamboos

    Some might remember those Bamboo instruments that I made a piece for some years ago. Then I wanted to do something different with it, and here I made a live piece using them. Here I use(make) them as resonating ‘electronic flutes’ using audio feedback system. When I close the holes, their original tone varies. The feedback works like ‘breathes.’ Then I apply a number of signal processing. Together with it, I attached small metal rings on the holes that are wired to Arduino that gives a low voltage flow. My touch could change its voltage as I am also connected to another analog circuit. In other words, the voltage flows throughout my body and whenever the contact is made between me and the instruments, it changed. The variation is chaotic, unpredictable. Then this signal is added to the feedback sound, which is related also to the movement of my fingers. The program note for the piece is below.

    Notes on “Bamboos”: Bamboos, their bodies, their own resonating voices. Every other gesture drives from there, as the performer continuously tries to distort, differentiate, and control them until the instruments and performer become strongly linked together. The whole space, occupied by bamboos’ stubborn voices whose struggles are running and jumping all over, later on becomes part of the resonating body, singing and breathing all together.

  4. Staff at the Institute of Sonology

    Probably the most surprising news was that I became a staff member in Sonology, where I studied and achieved Master Degree, for which I came here in The Netherlands. Somehow, probably it was my dream, one day, teaching here. Luckily and thankfully I got this opportunity.
    The subject I am teaching is ‘Spatial Music Composition for WFS system.’ The course is designed for students to plan and proceed their project with the WFS system and I give lectures on Spatial music with tons of musical examples of other composers, history on spatial music and spatialization system/tools, the meaning of space, musical space, and practical knowledge on how to use the WFS system. It demands quite some research that I enjoy very much. It is definitely a new experience for me, and there is far more to become better.

Well, that’s it. Now it’s the beginning of the new year 2018. I am very much looking forward to seeing what will come to my life. Hopefully it becomes a very creative, more musical, and inspiring year. It’s mostly up to me. 

I wish all of the readers a very happy new year!


Happy New Year + !!

It’s 2015!! I wish all who visit here happy new year! And please people who try to spam here, you too happy new year! (but please stop!)

I’d like to greet you with a video clip that I was involved as a sound designer. This is a test video for animation and sound. Thijs Geritz did the animation and I did the sound design, and we are willing to produce more such works.

About the sound, every sound was made in SuperCollider, sea wave and wind sound as well digitally produced with noise generators and filters. Some sound that has pitches was done with Supercollider Synthdef together with MIDI control. The final editing was done in Logic pro.

Enjoy the video, and hope we make more soon!

‘Bamboo’ for two Bambusoides and Computer

I’d like to introduce my latest piece ‘Bamboo’ for two Bambusoides and Computer.


The idea came when I was writing for Petzold (modern bass recorder) and experimented feedback effects with it. What I was doing was to use microphone inside and normalized the incoming signal without any air blowing into the instrument. Then a tone is created and the keys become a harmonic modulator. I couldn’t use this technique in another piece because it is feedback sensitive, creates some risks to blow the speakers, and didn’t have enough time to make it better. But I kept the idea.

Then I had this 3 meters bambusoides from a garden store, where I wanted to explore this idea, but I didn’t start working on it. And then I really wanted to try out with several different size of bamboos.

I cut the 3 meter’s bamboo in 3 pieces, one a long, and two shorts. They of course have a different resonant frequency (let’s say, soprano and alto). More interesting aspects with working with this Bamboo is its internal structure; it has the knots that are closed inside. However I think that the bamboos for the gardening purpose are treated with fire, and there was a small hall, a couple of centimetres in diameter, inside the bamboo. Because of this, every knots has slightly different resonant frequency and I wanted to use that.

I made two holes in each knots for the small bamboos, and one hole for the long one. One bamboo has 4 holes each, and I put a little loudspeaker in one side, and DPA microphone on the other side in order to create a feedback.

I love the sound of bamboo as a percussion too, so that the piece includes all the possible characteristics of its own: its percussive aspects, cylinder shaped instrument, flute like instrument, unstable yet quite organized resonant frequency, and so on.

Below you can listen to the piece. I am preparing for the video of the premiere. I hope you enjoy.
