Lacewing







This piece was commissioned and titled by Tim Walters.







This piece has two instruments – one uses the Ringz Ugen in SuperCollider and the other is a Sine wave which is phase modulated by another sine wave where both are tuned to the same frequency. It is in harmonic minor, tuned with the default just tuning.







Harmonic minor is known as “Mogen Ovos” to klezmer musicians. Rather than apply western harmony practice (except for the final cadence), every player is picking notes independently. The just tuning helps hold the notes in a key centre.

Shorts #41: Catalyst. Commissioned and titled by Andy Bannister







This piece was commissioned and titled by Andy Bannister.







Explaining why he picked this title, he said, “My thought process for this, is that the first half sounds like a catalyst for a reaction towards the latter half which could also be interpreted the sound of a substance or object changing state, like liquid to gas etc.”







The time elapsed between the original commission and this post is a lot longer than usual and I can’t remember how the piece was made, but according to my filing system, it was made using chaos synthesis on a Eurorack. This is a type of frequency modulation where oscillator A modulates oscillator B, which modulates oscillator C which modulates oscillator A. This is an exciting system because the feedback makes it chaotic.

Glass – for Irene’s birthday







This piece was composed using SuperCollider and a synthesiser for Irene’s birthday. It was presented as a part of an installation at the Rupture Gaming Festival in Kent.







The source material is recorded with an analogue modular synthesiser. The SuperCollider program takes that material and granulates it, dramatically changing the playback speed.

Sawtooth Minimalism







My colleague, Jackie Walduck, was showing students how to create phase music by putting loops out of synch in a DAW. Then I went home from teaching and created a PD patch to play low-pass filtered sawtooth waves, as an example for a different class. I got curious how much easier it would be in SuperCollider and created a tiny program that did the same thing and set it going at the same time. Then I started it again. The phasing was fixed, but it called to mind the shifting relationships of earlier that day.















This version is only SuperCollider, but it uses a non band limitted sawtooth to mimic phasor~ in PD. This version is 7 minutes long, but the proper version should be about 3 hours. I get lost in the phasing and feel relaxed.







I’ve attached the code below. If you want to to last longer, look for the number 340 – that’s 5’40” in seconds. Make it as long as you’d like.

The Last Christmas: III Misterioso







As per holiday tradition, I have again produced a Christmas album, although only an EP this year – or a virtual chamber ensemble playing once piece in five movements. This movement is the odd one out, using the same MIDI data for pitch and rhythm as the other movements use. The only sound used, however, is one sample. The same sample appears in all the movements at least once, but in them it is untransformed.







Also per holiday tradition, this is intended as a fundraiser for a worthy cause. Please consider donating to UKLGIG. cafdonate.cafonline.org/111#/DonationDetails They support LGBTQI+ people through the asylum and immigration process. Their vision is a world where there is equality, dignity, respect and safety for all people in the expression of their sexual or gender identity. Or, if you are in the US, please donate to the National Center for Transgender Equality secure2.convio.net/ncftge/site/Donation2;jsessionid=00000000.app268b?df_id=1480&mfc_pref=T&1480.donation=form1&NONCE_TOKEN=C5EA18E62F736227261DC4CE5C50ADBE







If you are interested in hearing the rest of the album, it’s on bandcamp https://charleshutchins.bandcamp.com/album/the-last-christmas. This movement is my favourite one and the only one I’ll post here, lest this turn into a Christmas podcast. I’ve written a post about how the whole piece was made on my blog.

Santa Loves You

I was extremely startled to hear the religious content in the second verse of Here Comes Santa Claus. It seems the authors were responding to criticism of the secular/commercial focus of most Santa-based songs and thus were trying to have it both ways.

The addition of God only increases the tension of the culture war’s resonances within this song. Instead of including Jesus, the song instead seemingly elevates Santa to part of a pantheon.

The attempt to tackle class is even less successful – Santa may love children who are rich and poor equally, but they don’t get equal presents.

This is the last song in this year’s Christmas album. If you enjoyed it (or not), please consider making a donation to the Hackney Night Shelter, which my wife has been volunteering at. There are very few shelter beds in East London. This roving shelter makes up a large percentage of them.

If you’d like to download this album in higher fidelity than is available here, you can find it and cover art over at bandcamp. It’s a free download, but please do make a donation directly to the shelter!
