Found this nice ISMLP category page while starting research for a new project, containing enough baroque French gurdy scores to keep anyone busy for a while imslp.org/wiki/Category:Scores_featuring_the_vielle
There’s all sorts of interesting stuff if you poke around a bit — for example, in Bordet’s Méthode raisonnée pour apprendre la musique there’s a summary of the hurdy gurdy which suggests that extended keyboards beyond the usual two-octaves-minus-high-F# existed, but were “extraordinaire, et peu usité:”
Cookin’ up a new gurdy preamp with even less noise than before. The secret ingredient? The pot itself! Turns out EM shielding is every bit as important as all those grumpy people on guitar forums spend their spare time telling each other.
Augmented Hurdy Gurdy Experiments
As I can’t currently commit to building a new series of gurdies due to my living situation, I’ve been keeping myself busy developing the MIDI system for my instruments, to develop new extended, augmented playing techniques.
This video is the first demonstration of some hybrid electronic-acoustic experiments using the prototype MIDI system installed on my hurdy gurdy.
0:22 Technique: Pitch-shifting Polyphony
Gurdy MIDI and Audio → Apogee ONE → Macbook running a puredata patch
Monophonic acoustic gurdy signal is pitch-shifted down in real time to play chords and harmonies. Chords and intervals on the keyboard can also be used to pitch-shift the trompette signal (0:55) or the drones. Inspired by an idea from Sébastien Tron.
1:18 Technique: Expressive MIDI Controller
Hurdy Gurdy MIDI → DIY Hybrid Poly Synth based off Mutable Instruments Ambika
The keyboard and wheel sensors send MIDI note, expression and polyphonic aftertouch messages to a polyphonic synthesizer. In this case a split keyboard effect is used to play two sounds.
1:36 Technique: Layered Acoustic and Electronic Sound
Hurdy Gurdy Acoustic audio, Gurdy MIDI → DIY Hybrid Poly Synth based off Mutable Instruments Ambika
1:36 The acoustic string plays a melody, the bottom half of the keyboard controls a synthesizer with a long release for subtle held chords
2:08 Using trompette technique can send MIDI messages, used here to play synthesized percussion on an Ambika voice assigned to MIDI channel 10, whilst the keyboard plays chords.
2:30 Acoustic trompette and melody string sound layered over subtle polyphonic synthesized chords
After missing the crowdfunding campaign, I was happy to finally be able to buy a copy of Tobie Miller’s excellent Bach solo hurdy gurdy CD at Chateau d’Ars last week. I couldn’t find any official album artwork on the web yet, so here is a quick scan of the cover, for anyone else who got a copy already.
I’ll be at the Mazurki Festival Tagowisko Instrumentów (Musical Instrument Exhibition) with my instruments on Saturday the 28th. It’s not on the English programme, but is on the Polish one so is definitely happening! Come and try out my gurdies, and see my (experimental) MIDI system and hybrid synth in action!
Hurdy Gurdy #7, finished and picked up by the customer!
3x chanters, 2x drones, 2x trompettes, 4x capos, 4x sympathetic strings, 3 channel active preamp system. Very happy with how this one came out — in fact I need to retro-fit some of the electronics changes onto my own instrument… No more 50Hz hum!
Video: The Poisonous Polonaise (Polonoise No. 19, Wittenberger Apothekenhandschrift, Deutschland)
More music from Emilyn, John and me!
This one is a beautiful polonaise found in the Wittenberger Apothekenhandschrift, a hand written dance manuscript found in the Giftschrank (poisonous substance cabinet) in an old pharmacy in Wittenberge, Germany.
Sheet music for this piece, and many other amazing northern German traditional music, can be found in volumes 1-3 of Neues aus Alten Büchern (new things from old books) published by Tramudea e.V., and also on tanzmusikarchiv.de and the TradTanzMusik youtube channel.
Recorded in Toronto, Canada on 2017-05-12
Video: Lights in the Sky (Barnaby Walters)
Finally the first video from my trip to Canada last month! Playing with Emilyn and John is always a blast, and this time we recorded a bunch of tunes. More to come!
A waltz I wrote whilst living in Iceland, recorded for the first time with Emilyn Stam and John David Williams on 2017-05-12 in Toronto, Canada.
Doing some prototyping+testing for the next MIDI-enabled gurdy board:
My current approach is an Arduino (Genuino) Uno with a custom made board with a line of hall effect sensors, and the various other boards plugged into the Arduino. It works, but there are various problems — wiring the whole thing together is a hassle; the limited I/O on the Uno requires me to multiplex the sensors, introducing delays; hand-soldering through-hole sensors means they’re all in slightly different positions; and a single line of sensors isn’t enough to cover the whole throw of a key, resulting in notes turning off when they’re bent too far.
I heard about emsproto.com and was initially considering designing a board containing the sensors and microcontroller myself, and having it built, but after drafting up a very simple one-component test board and seeing that there’s a base cost of €200 per board for PCB and assembly, I decided on another approach.
The next version of the board will be a custom designed sensor and breakout board with two rows of surface-mounted hall effect sensors, into which I can plug a Teensy 3.5, removing the need for multiplexing, vastly increasing the speed at which the system can run, and opening up various possibilities like easy-to-implement USB-MIDI support.
