The latest root of sine collection demonstrates a clutch of talented artists exploring the way of the sine. Employing diverse techniques such as the glitch melodics of Michael Santos to the chaos patterns of Johan Zwart the results are compelling.

just intonation [henry walmsley]

This track was written to demonstrate the harmonic possibilities of using higher harmonics freely whenever the composer wishes, without the bounds of a traditional scale, but within the bounds of major/minor/seventh harmony. It is also quite funky!

Harmonics of 11ths, 13th, 23rds etc are prominent in this composition, without being overwhelming in their unusualness. The highest prime harmonic used was the 127th harmonic in the final melody! E#''' was also used (125th harmonic)

It was written using a new notation system which has been devised to make accessing higher harmonics as intuitive as possible (it still takes a bit of getting one's head around!). Please contact me if you would like to see the score written in this notation system, or for details about how this notation system enables interesting harmonic composition outside of the bounds of the Western 12-note scale to be realised.

It qualifies for chiptune since although it is (much to my shame) 16-bit 44100Hz audio instead of the pure 8-bit, the sounds were synthesised from scratch using modified sin/saw waves, with a bit of band-limited noise thrown in for good measure. The synth took as input CSV 6xN matrices as sequence files, and processed in Octave/MATLAB to give MP3 output which you hear here.

update 10th Apr 2015:

Here is a brief description of how the MP3 track was generated:

Just Intonation Notes (1/1 4/3 7/4 etc) <-> New Notation System (C F `Bb~7 etc) which is easier to read than pure numbers and where the letter corresponds (roughly) to the position in the 12ET scale
-> Excel block of chords and melody notes for visual presentation to composer (.txt)
-> Excel long (~1700 columns) of calculated note letters, frequencies, note lengths, etc
-> Excel final sequence file with 6 columns: channel, start time, frequency, note length, loudness, stereo position (.csv)
-> Octave/MATLAB code to take the 6 columns and turn them into chiptune (.mp3 or .wav)
-> Sometimes extra post processing in Audacity for final .wav

Sonata 1 'Cheery' - Chip Synth, Justly Intoned

Re-ignition

https://shimmeringmoodsrecords.bandcamp.com/album/spaces-between-words

In a world where every word carries weight, UK based electronic producer Simon Vince (HERE) invites listeners into a sonorous exploration of the unnoticed silences and spaces. With his latest ambient album and second release on Shimmering Moods ; Spaces Between Words. HERE crafts eight beautifully fragile and melancholic electronica tracks that delve into the delicate nuances of love and loss. 
Each piece is a hauntingly wistful soundscape, woven from electro-acoustic ambience and drones to shimmering synths, delicate textures, and gentle pulses that evoke the bittersweet essence of separation. 

From the emotive echoing tones in “Spaces Between Words” to the nostalgic reverberations and drawn out chords of “I Find You In Whispers" this album invites you to embrace the unspoken and the unshared, allowing you to linger in the quiet spaces that define our connections.

HERE - Spaces Between Words

I may not trust the intarwebs, but I will surely trust my label. When it comes to discovering new music (to pop me out of my echo chamber and insistent feedback loop), it’s easy to get lost among the new releases. There’s just too much of everything, and it’s only getting harder to discern. Anyone can share their latest content. And anyone can upload with a click. There’s a reason for that. The companies that host it all have made it easy for a reason: to monetize your music. To turn your content into cash. On the flip side, the labels take their time. They are, in turn, investing in the artist. So when you buy into the label, you buy into their world. Past Inside The Present has been curating my journey since 2018, and I have learned to trust Zach’s choice in music. So when he backs North Carolina-based vocalist Angela Winter for her slightly avant-garde solo debut release for the label, I’m all ears. I write “solo” because in 2024, we’ve already heard her voice on a collaboration with the label boss himself, titled Mid Sky. Together, the duo navigated “a realm between the terrestrial and cosmic with organic drones and ethereal vocals“. In August, Angela returns with a full-length titled Forbidden Questions In Space, centered around ambient and drone improvisations, and of course, her voice, for a koan-inspired drift into the endless cosmos. If you’ve been following Headphone Commute, you know that I tend to focus on mostly instrumental music, often with a darker tint of sonic experimentation. Today, I select one of those pieces from her upcoming album to give you a taste.

Ambient minimalism is gaining momentum. Some would argue that evoking atmosphere is harder than sequencing beats, and Fragments of Silence is proof. Laden with lush textures and ambient leanings, the album invites deep listening.

This 8-track LP marks the debut collaboration between Synthbiont, Anassimandrus, and Sacred Seeds: three artists with distinct sensibilities, united by a shared affinity for ambient, experimental, and dub techno sounds. Their convergence sets the tone for a singular, immersive experience.

Fragments of Silence is not background music. It’s a serious body of work that commands attention. It’s an hour-long descent into a vacuum chamber. An environment that evolves, coils, shifts, and builds toward dissonance and stillness.

Each track is grounded in a strong atmospheric character, unfolding with deliberate progression. The album leans heavily into experimental minimalism, imagine dark tunnels, ominous energy fields, and brooding landscapes.

Fragments of Silence is one of those albums that explores the intersection of distinct creative temperaments, marked by structure, mood, and experimentation. The result is an album that flows with intention and feeling, creating a space that listeners can fully sink into.

Description by SreeLakshmy 

Sacred Seeds is an ambient electronic music project by Wasim, founded in 2014 in Calicut, Kerala (India). Blending synthesis, field recordings, and experimental sound design, Sacred Seeds’ music explores the interplay between organic and electronic textures.

Sacred Seeds has performed at renowned festivals such as Magnetic Fields, Hilltop Festival, and Bloom in Green, sharing the stage with influential artists like Gaudi, OTT, Suduaya, and Symbolico, and many more.

Synthbiont & Anassimandrus is the ambient/experimental/dub techno project born at the end of 2018 by the collaboration between Nicolò Faggiani and Tommaso Gobbo. Their musical background comes from different musical experiences as DJs, vinyl collectors, and founders of EMC series. Their performances and music are composed through the elaboration of different digital and analog sources, processed field recordings, and sampling to create unique soundscapes.

Produced and mixed by Nicolò Faggiani and Tommaso Gobbo (Synthbiont & Anassimandrus) (1,2,5,6) and Wasim Raja (Sacred Seeds) (3,4,7,8)

Fragments of Silence

Warmth in Silence (Synthbiont & Anassimandrus Rework)

This is a justly intoned arrangement of J. S. Bach's Prelude in C Major, the first Prelude of the 48 Preludes and Fugues, a body of work by Bach which demonstrated that with tempered tunings every major and minor key was usable.

As well as being one of my favourite pieces of music, I thought it would be worthwhile to demonstrate that this music sounds just as interesting (maybe more interesting!) in Just Intonation (JI), where exclusively rationally-spaced intervals are used. JI is the natural way of tuning intervals. It derived from harmonic series, which are produced by string and wind instruments.

Due to the 'wrap-around' nature of tempered tunings, some transitions (e.g. D minor to G major) are good transitions in tempered tunings, but sound 'further away' or less harmonious in JI. Also, transitions from ,D' to `D (10/9 to 9/8) and from C to `C~7 (1/1 to 63/64) are noticeably microtonal shifts. Some people might like them, some might not. Personally, I like them. The major advantage is the purity of all the triads and seventh chords, which in my opinion outweigh the 'disadvantages' of having noticeable microtonality.

As always, I've slipped in an 11th and 13th harmonic (the 11th is obvious, the 13th less so). I refuse to write any new music which does not contain both 11th and 13th harmonics.

Another interesting feature was Bach's usage of diminished chords. My favourite justly intoned diminished chord is the sequence 10:12:14:17:20:24:28:34:40 etc. Hence, some 17th harmonics have been used, wherever there is a diminished chord, in both 17/1 and 1/17 formats (and 5/17).

Hence, this track contains all the harmonics 2, 3, 5, 7, 11, 13 and 17. I will attempt to remedy the lack of 19, 23, ..., 127th harmonics in my next upload.

Enjoy!

Dave

Ethan Syann - VI

This is a justly intoned arrangement of Chopin's Etude in C Major (Opus 10, No. 1), the first Etude of his series of Etudes which demonstrated his new piano performance techniques.

Although Etudes are usually technical exercises, Chopin's are special since they are immensely listenable with intricate harmonies.

I have retuned Chopin's harmony to have much more than 12 notes to the scale. More to come (hopefully soon!) about the notes which have been used. Concisely, the major and minor triads and sevenths have almost everywhere been preserved, and Chopin's use of sequences leads the harmony down very interesting and long paths in the 7-limit tonal lattice. A couple of jarring transitions are where the harmony jumps up by a syntonic comma (or 7-limit comma). As always, 11th and 13th harmonics are smuggled in, in some of the diminished chords near the end.

Enjoy!

Dave

It has been about 53 months since the last solo Purl album was released. 'Renovatio' marked the end of an emotional process related to music-making that I felt had become too heavy for me to continue, and the title signified the rebirth I felt was necessary. I thought at the time that perhaps this would be the last Purl album.

Since then there have been 17 singles, EPs and collaborative albums released that in different ways opened my mind and heart beyond anything that came before. There has also been solo releases planned that did not happen (yet), for different reasons.

'Himmelsandar' isn't really something new. Then again, I wonder if there ever has been or will be anything new from this stream of awareness and emotion that I call Purl. It somehow seems to me like everything essential was present from the beginning, and I'm not sure if anything has been added to it since. I dream of starting new projects; painting on a blank canvas again. But nothing here was painted on such a canvas. Everything was painted and repainted, so many times that the original idea may no longer be distinguished other than as the faintest wisp of something... ethereal.

a song for the birth of a love with no conditions
uncovering purl in a vast bustling city
moments of quiet wonder
lost and found in the constancy of motion

'livet vänder inte åter' was composed in the city of İstanbul during the past moon of December. It contains fragments from vastly different parts of my life, blended with recordings made while wandering among these continual streams of people, animals, vehicles of all kinds, passing street musicians on the way down to the calming waves of the strait, the seagulls circling above. Everything somehow falling together, in me, and I, a part of everything.
