Filed Recording at Riverside (September 2018)

What is Filed Recording?

“Filed Recording” is the term used for an audio recording produced outside a recoding studio, and the term applies to recordings of both natural and human-produced sounds. Field recording of natural sounds, also called phonography, was originally developed as a documentary adjunct to research work in the filed, and foley work for film. “Field recordings” may also refer to simple monaural or stereo recordings taken of musicians in familiar and casual surroundings.


Yasuharu Nagura has performed a new live recording entitled 『Bugs in A Silent』that is recorded September 17, 2018. First, he recorded field sounds of insects at riverside under the moonlight. Next, in accordance with the sound, the sound of water was expressed with a step/sequencer. Finally, he improvised with a synthesizer using the blue note scale.

The Principle of the Analog Modular Synthesizer

What is the analog modular synthesizer?

The analog modular synthesizer is a type of synthesizer which exists in both physical and virtual forms, consisting of separate specialized modules. The specialization is usually in the module being designed to allow the modification or processing of one parameter of a signal, such as the frequency (oscillator), spectrum (filter), or amplitude (amplifier). The modules are not hardwired together but are connected together with patch cords, a matrix patching system, or switches to create a patch. The voltages from the modules may function as (audio) signals, control voltages, or logic conditions.

In general, when introducing modular synth, selection of modules for assembling the system is an important event before purchase, and it is the real pleasure of modular synth. But for beginners of analog modular synthesizer, it will be the first major hurdle. Choosing a module yourself is a very difficult problem unless you understand what you need and what you want, clear vision and knowledge. Therefore, I will explain the basic knowledge of the sound source circuit, the circuit in charge of the control signal, and the control standard.

Configuration of sound source circuit
The analog modular synthesizer is basically composed of the following circuits.

Circuit in charge of audio signal
The three functions in charge of the audio signal are as follows.

Abbreviation for voltage controlled oscillator. An oscillator that creates a basic waveform.

Abbreviation for voltage controlled filter. A circuit for processing waveforms.

Abbreviation for voltage controlled amplifiers.  A circuit for controlling volume.

Circuit in charge of control signal
The main circuits for controlling the above three functions are as follows.

Envelope Generator
A circuit that generates a voltage that varies with time by four parameters: Attack / Decay / Sustain / Release (Reverberation).

Abbreviation for low frequency oscillator. Send a low frequency as a control signal to the control circuit of the audio signal, giving a periodic change (For example, if you send it to the VCO, you can create a vibrato).

Keyboard or Sequencer
Function to input performance information.

Control Standard
An analog modular synthesizer roughly controls each function by sending and receiving two types of information as voltage.

Signal on / off information. Control the length of the sound.

Abbreviation of controlled voltage. Control the value of each function, beginning with the interval.

In the case of a modular synthesizer, it is possible to more flexibly modulate the audio signal with a patch cable.

latest collections | 『Otsu』,『Omi Hachiman』,『Hikone』, 『Samegai』(2018)


I stayed in Otsu city, Shiga prefecture. After crossing the Biwako Bridge, I looked at the Biwako Bridge from the Biwako Ohashi Kome Plaza. The view of Lake Biwa from the balcony at the second floor was outstanding. At the restaurant, I ate Omi beef. It is one of the best beef in Japan. Omi beef is raised in the rich nature represented Lake Biwa. It is the roots of Tajima cattle that was originally used for aguriculture. We call the mix of meat and fat “sashi.” Omi beef has fine sashi overall. In the Edo periodo, there was a history that it was eaten by Daimyo, and it is still popular now.


I climbed to the mountaintop station of Mt. Uchimi (1,105m) by a ropeway. From there, I moved to the top of Mt. Horai by the lift. The highest peak of Mt. Horai is 1,174m. I could see sea of clouds and Lake Biwa. On sunny days, you can see Lake Biwa, Mt. Ibuki, and Mt. Hira.  It was a luxurious space in the sky that can be reached by ropeway.


I stayed in Omi Hachiman city. I took a walk through Hachiman moat, Himure Hachiman Shrine, and Shinmachi street (the street of Omi merchant). I felt the life of Omi merchant with frugality, simplicity, and fortitude. Next, I went to Hikone castle in Hikone city. I watched Hikone Castle from Genkyuen. Genkyuen is a stroll garden with a central pond. You can watch the scenery around Hikone Castle as a large garden in the early Edo period. Finally, I went to Samegai, Maibara city. Along the Jizo river at Samegai, the cityscape is still continuing. Jizo river is famous as a group of “Bai-ka-mo”(plum, flower, and algae) in a river made of fresh water spring from the area. Samegai is selected as a Japan heritage as a culture of water and prayer.


The Difference between Mixdown and Mastering

mix down & mastering by Yasuharu Nagura | the highest sound quality with 44.100 kHz, 16 bit, wav file

“Mixdown” is to adjust the volume and sound quality of each instrument in the song. It is like rasping on furniture. Because each musical instrument is played on a separate track, each unit can be raised and lowered. You can apply echo and other effects to songs. You can also adjust the pitch of the song.

Making the final polishing work is called “mastering”. Throughout the album, it is to match volume and sound quality so that you do not feel uncomfortable even if you listen to each song. It is like painting varnish on furniture. You can adjust the sound pressure using designated software. Currently, there are mastering service by artificial intelligence.

New Album “On the Music of the Heavenly Spheres” (2018)



Yasuharu Nagura has performed a new live recording entitled 『On the Music of the Heavenly Spheres』that is released August 1, 2018.




In ancient Greek music theory, music harmony (Harmonia) was thought to be the same as harmony of the universe. It is the idea that the operation of the celestial body emits sound and the whole universe plays harmony. This was called “celestial music.” At the root of this idea, the universe is based on the principle of numbers. And there is a Western traditional idea to embody this principle by music. This album was influenced by the philosophy of “celestial music.”

Sojorn, Gujo City – Riverside-

The town was founded in 1559 in a small mountain valley next to the Nagara River. Here, two fast running rivers, both tributaries of the Nagara River, create a natural moat around an area at the foot of a small mountain – known locally as Mount Hachiman. Over time, a small town blossomed and grew in this protected are below the castle.

スクリーンショット 2018-10-13 17.38.57

The following message was sent to me through the contact form on my Bandcamp page.

 Hello Mr. Nagura,

i am a big fan of your creative work and i started creating music myself so i did a Remix of your Track “A Buddy From Rio”. You can find it on Soundcloud. If you dont like it and want it removed, just let me know.

p.s. I would like to express my sincere gratitude for your efforts toward this project.

Currently, there are four unreleased sound sources.

New Album “The Recovery of Soul Life” (2018)


Yasuharu Nagura has performed a new live recording entitled 『The Recovery of Soul Life』that is released May 6, 2018. He performed “the recovery of soul life” on analog moduler synthesizer.

The concept of album is to restore the life of the soul. It is not special. It is to restore the feeling of joy and sadness in daily life, such as village festivals and dedication to deceased people. It is to recognize that the street trees flying at equal intervals are olive trees growing gently.

People do not know what they want. Everyone is moving around because they do not like where they are. Everyone is asleep or yawing on a running train. Children only know what they are looking for and they are lucky. People are not sure what they are seeking because they are corrupted by the culture of ready-made goods and the culture of standarized goods. People can be truly satisified by showing their creative abilities. “Emergence!”
