On March 27, 2019, People Inside Electronics presented Wired Wednesday, a concert featuring a set by Amy Advocat and Matt Sharrock, the Transient Canvas duo – as well as a sound installation premiere and a new piece for augmented trumpet. All of this was at Live Arts LA, a dance studio whose spacious performance floor was ideal for the occasion.
According to my friend, who’s blogged for a list of online poker sites that range from unknown to the biggest ones – the first piece on the concert program was the world premiere of bzbowls (2019), a sound installation by Stephanie Cheng Smith. This consisted of some 15 plastic bowls suspended between fine wires, and each bowl fitted with a tiny vibration motor – like the one that vibrates your cell phone when you get a call. These were wired into a control panel so that the speed and intensity of the vibrations could be varied. As the motors were activated, Ms. Smith added various objects to the bowls, changing the pitch and timbre of the sound. Ping pong balls tended to lower the pitch and raise the volume. Small beads and bells generally resulted in a higher pitch and created a more musical sound. Adding a few tiny clothespins to a bowl produced a distinctive growl. Plastic cups were occasionally placed over the contents of the bowls and this tended to muffle the vibrations, but at times also seemed to amplify the sounds. An overhead projector gave the audience a view of what was being placed into, or removed from each bowl.
The 15 motors and the items inside the bowls produced an active overall sound, and it was a bit like being inside a small machine. There was a distinct sense of motion, but not necessarily of movement. The objects in the bowls were removed and replaced gradually so that the character of the sound was continuously changing between a low roar and a high ringing jangle. The motor controller had a pulse mode, so that the vibration motors cycled on and off for a second or two, and this had the effect of further exaggerating the sense of motion. Although generally percussive in nature, the sound seemed to gradually shift and change almost as a living organism. The ingenuity applied by Ms. Smith to a collection of simple materials made bzbowls an intriguing, miniature sound world based on artfully controlled vibration.
Next was The Sameness of Earlier and Later Times and Nows (2019), by Sarah Belle Reid, and this was also a world premiere and this was scored for augmented trumpet, laptop and modular synthesizer. The augmented trumpet is an impressive extension of the standard instrument and according to the concert notes “…uses sensor technology to capture gestural data such as valve displacement, hand tension and instrument position which is then converted into control information to interact with other instruments and systems.” Ms. Reid performed with great poise as she played the trumpet into a microphone where the sounds were processed by the synthesizer and PC before re-emerging through the speaker system. Maybe a third of what was heard during the course of this piece could be described as standard trumpet sounds, and even here the confident intonation by Ms. Reid left nothing to be desired. The tone from the horn was smoothly elegant, and the looped delay and processing only added to the intrigue. The feeling of the piece was both innovative and comfortably familiar. The sensors on the trumpet added greatly to the variety, including a new subset of percussive effects. Clicks, thumps and pops from the valves and triggers on the horn entered the mix, as well as the roar of breathy sounds in the absence of tones. As The Sameness of Earlier and Later Times and Nows amply demonstrated, Ms. Reid has greatly extended the possibilities of the humble trumpet into new territory by the application of innovative sensing technology and sound processing.
