Fabio Viola These sounds are the definition of ethereal and otherworldly. Beautiful, immersive ambient music that takes you on a cosmic journey. Pulse Emitter is one of the greats. Favorite track: Fog Land.

danilunaria Xenharmonic Passages is like a journey to another planet where landscapes and beings are surreal and beautiful. You don't understand them but somehow you feel at home. Outstanding electronic music!

Joshua Stefane Weird, wonderful, and entrancing! As pleasing to the ear as it is challenging, this ranks up there with some of the best experimental/ambient music I know. Personally, it makes me want to be a better composer. Thanks Pulse Emitter!!

“The latest from the ever-prolific synthesist and experimentalist Pulse Emitter is a formalist exercise in pushing into the unknown galaxy of microtonality—essentially meaning that it consists of intervals and scales not traditionally explored in Western music. This is interesting to us the layperson listeners not because its conceptually groundbreaking, but because great art is often made under rigorous methodologies. And truly this is one of Pulse Emitter’s most wonderful and strange works in a catalog full of them, a collection of landscapes as colorful and alien as anything the ProcGen big bangs in No Man’s Sky have been able to dream out of raw data. It’s a whole new world, crafted with a hand tied behind its creator’s back.” – Noisey / Vice

All of these compositions use tunings other than the common twelve-tone equal temperament (12-TET). The tunings for each piece are as follows:

7-TET - track 7
10-TET - track 2
14-TET - track 4
19-TET - tracks 1, 3, 5, 6, 8, 10
31-TET - track 9

This music is 100% electronic, made mostly with software synthesizers.

Pulse Emitter is Daryl Groetsch, in Portland, Oregon.

Released on the Expansive label.

Xenharmonic Passages is the outcome of Pulse Emitter’s explorations in microtonalism, specifically various equal temperaments. Experimenting with these tunings the artist found new emotions and colors to work with. These pieces pair a minimalist, ambient style with the creation of alien insect-scapes to complement the otherworldly atmospheres of the microtonal melodies. Each of Xenharmonic Passages’ ten tracks are themselves passageways to other places, real and imaginary. Get ready to relax and be transported with tones from another plane.
