Low. Low Noise

some frequencies below 20 Hz (say, 16 Hz) can be perceived as audible sound by about 6% of men and 18% of women, up to distances of 40 km in certain atmospheric conditions (a stable layer of air next to the ground). As a result, the lady in question in the memoir must switch the radio on in order to be able to sleep.

You can hear very low-frequency sounds at levels above 88–100 dB down to a few cycles per second, but you can't get any tonal information out of it below about 20Hz—it mostly just feels like beating pressure waves. And like any other sound, if presented at levels above 140 dB, it is going to cause pain. But the primary effects of infrasound are not on your ears but on the rest of your body.

No Darkness Suite

  Piece 'No Darkness Suite' is similar to a fantastic nocturne, but it sounds light and positive. It's hard to find a video for such music, so I got a film that I shot in 2022 during the Kyiv blackout - I just went out into the street, which was in complete darkness, you don't see that often.  For the first time in my practice, I used the Ukrainian national instrument with 64 strings - the bandura. Why bandura? Because I have it (my son is learning to play on it) and I've been eyeing it for a long time.   I hope you will not fall asleep and listen to the end.  Дякую! Thanks! 

Electro House Free Jazz Guitar

It seems that is a nice family - Electro House Techno vibe and free jazz guitar. Sometimes I have an impression that sax would be on the pair. Another point - I can't add some trendy bebop line. I don't use any fx-pedal, guitar sound is SX guitar and Logic. The latest mix has deep boomy house kick I like and athmospheric far guitar. Indeed that is a Green warm humbucker on the vacation, which became Tele.

Halfsteps 2. Diffused, sleepy and relaxed

I continue to make halfsteps ) and have posted a new video called Halfsteps 2 [Free Form Jazz Guitar]. It uses the same static footage (the same October crossroad), but now that is the movie with a people crossing street. I know that is amateurish, mobile video is not a Dolby TrueHD , but today that is the plus. Guitar tone is solid and round, melodical line is diffused, sleepy and relaxed.  Compare with the first Halfsteps .
