OTTAWA, Ontario, May 15, 2024 – The electric guitar has been a core element of popular music for much of the past century. Pickups are the components that turn vibrations from the strings into electricity for sound and can be seen as the “heart” of the instrument. Electric guitarists have long known that the magnetic force from pickups affects the quality of their sound and how smoothly the sound transitions, known as timbre.

Takuto Yudasaka, visiting scholar at McGill University and researcher at Yamaha, will present their work on the physics behind electric guitar pickups Wednesday, May 15, at 10:30 a.m. EDT as part of a joint meeting of the Acoustical Society of America and the Canadian Acoustical Association, running May 13-17 at the Shaw Centre located in downtown Ottawa, Ontario, Canada.

“In electric guitars, the vibration of a magnetized string generates an electric current in the pickup coil,” said Yudasaka. “This current is very weak, but by winding the coil thousands of times, more signal can be detected.”

The details of how the pickup coil is wound has a significant impact on the resulting sound of the instrument. Winding the coil more will increase the output volume, but a coil wound too much can begin to lose its clarity. A minuscule winding of the coils, even as small as a hundredth of a millimeter, can make a noticeable sound change to a trained ear.

Furthermore, variables such as the type and thickness of the wire, the winding pattern, the shape and size of the pickup, and even the type of magnets used can all influence the guitar’s sound. While the average listener may not pick up on it, electric guitarists have both noticed and been intrigued by these physical phenomena.

With such a range of choices, finding the perfect sound can be a challenge, one Yudasaka and his colleagues hope to address.

“We were able to understand how the magnetic force of pickups affects the sound of electric guitars and how we can simulate it,” said Yudasaka. “This simulation has the potential to not only reduce design time but also to enable the development of electric guitars with new timbres.”

This understanding allows guitarists to make customary pickup selections and adjustments purposefully, removing most of the guesswork involved.

Yudasaka along with collaborators at Yamaha and McGill University will continue their research on how pickups affect timbre through future simulations.

Courtship Through Flute Song in Indigenous Southern Plains Culture #ASA186

For some tribes, performing an original flute song is the first step toward marriage.

OTTAWA, Ontario, May 14, 2024 – Every love story is unique, and in traditional Indigenous Southern Plains culture, it begins with an original ballad performed on the flute. In order to win a lover’s affection, and respect among the tribe, each pursuer must compose one good flute serenade.

“Warrior with flute” by Timothy Tate Nevaquaya.

Paula Conlon, a former music professor at the University of Oklahoma, has researched the history and cultural significance of the Indigenous flute since the 1980s. Conlon will present her work Tuesday, May 14, at 9:45 a.m. EDT as part of a joint meeting of the Acoustical Society of America and the Canadian Acoustical Association, running May 13-17 at the Shaw Centre located in downtown Ottawa, Ontario, Canada.

Conlon’s deep dive into this tradition includes a focus on four aspects that make a flute song “good” music: characteristics of the musical elements within the song, features that epitomize quintessential flutes, the qualities of the individual flute player, and how the flute players serve in their respective communities as mentors and role models. She also found that a love worth pursuing inspires its own music.

“Traditionally, a flute player would not use the same love song to court multiple partners, similar to a love letter or love poem,” said Conlon.

To study this romantic art form, Conlon looked to the works of flutists who helped maintain the tradition.

“The findings are based on an analysis of historical recordings of Indigenous flute love songs and the related literature, and the flute songs of Kiowa flutist Belo Cozad and Comanche flutist Doc Tate Nevaquaya,” said Conlon.

The decline of this courting tradition followed the end of the Reservation Era in 1887. Cozad and Nevaquaya are recognized for the survival of the Plains’ flute tradition, and nearly a century after the Reservation Era, in the late 20th century the tradition experienced a resurgence.

Nevaquaya was a leader in the Indigenous flute revival. He learned how to construct the flutes, personalized playing techniques, and put a spotlight on the old repertoire. He notably developed two new composition styles — one for modern courtship and the other to expand on the creativity of the individual flutist. His solo flute album, released in 1979, is regarded as a bridge between the traditional culture and the style of up-and-coming flute players.

“In 2024, it is another generation of Indigenous flute players, including Nevaquaya’s sons, Timothy, Edmond, and Calvert, who are making their mark,” said Conlon.

During her two-decade-long tenure in Oklahoma, Conlon developed relationships with many of the Indigenous flute players in the area. Now living in her hometown of Ottawa, she plans to continue this investigation by conducting comparable research on Indigenous flute players in Canada.

Popular version of 4aMU6 – Ultrasound tongue imaging of vowel spaces across pitches in singing
Presented at the 186 ASA Meeting

–The research described in this Acoustics Lay Language Paper may not have yet been peer reviewed–

Singing isn’t just for the stage – everyone enjoys finding their voices in songs, regardless of whether they are performing in an auditorium or merely humming in the shower. Singing well is more than just hitting the right notes, it’s also about using your voice as an instrument effectively. One technique that professional opera singers master is to change how they pronounce their vowels based on the pitch they are singing. But why do singers change their vowels? Is it only to sound more beautiful, or is it necessary to hit these higher notes?

We explore this question by studying what non-professional singers do – if it is necessary to change the vowels to reach higher notes, then non-professional singers will also do the same at higher notes. The participants were asked to sing various English vowels across their pitch range, much like a vocal warm-up exercise. These vowels included [i] (like “beat”), [ɛ] (like “bet”), [æ] (like “bat”), [ɑ] (like “bot”), and [u] (like “boot”). Since vowels are made by different tongue gestures, we used ultrasound imaging to capture images of the participants’ tongue positions as they sang. This allowed us to see how the tongue moved across different pitches and vowels.

We found that participants who managed to sing more pitches did indeed adjust their tongue shapes when reaching high notes. Even when isolating the participants who said they have never sung in choir or acapella group contexts, the trend still stands. Those who are able to sing at higher pitches try to adjust their vowels at higher pitches. In contrast, participants who cannot sing a wide pitch range generally do not change their vowels based on pitch.

We then compared this to pilot data from an operatic soprano, who showed gradual adjustments in tongue positions across her whole pitch range, effectively neutralising the differences between vowels at her highest pitches. In other words, all the vowels at her highest pitches sounded very similar to each other.

Overall, these findings suggest that maybe changing our mouth shape and tongue position is necessary when singing high pitches. The way singers modify their vowels could be an essential part of achieving a well-balanced, efficient voice, especially for hitting high notes. By better understanding how vowels and pitch interact with each other, this research opens the door to further studies on how singers use their vocal instruments and what are the keys to effective voice production. Together, this research offers insights into not only our appreciation for the art of singing, but also into the complex mechanisms of human vocal production.

Software DJ Creates Automated Pop Song Mashups #Acoustics23

Automated software mixes drums, vocals to create unique musical combinations.

SYDNEY, Dec. 7, 2023 – Song mashups are a staple of many DJs, who mix the vocals and instrumentals from two or more tracks into a seamless blend, creating a new and exciting final product. While the result is fun to listen to, the creation process can often be challenging, requiring knowledge and expertise to select the right tracks and mash them together perfectly.

Xinyang Wu from the Hong Kong University of Science and Technology took a different approach, designing a computer algorithm to intelligently create mashups using the drum tracks from one song and the vocals and instrumentals from another. He will present his work Dec. 7 at 4:20 p.m. Australian Eastern Daylight Time, as part of Acoustics 2023, running Dec. 4-8 at the International Convention Centre Sydney.

While some algorithms and automated software can attempt to create song mashups, their results are often clunky and unrefined. These methods layer the complete, unaltered tracks on top of each other, aligning them based on detected key moments in the music, rather than skillfully combining the vocals and instrumentals of different songs.

“Imagine trying to make a gourmet meal with only a microwave – that’s sort of what automated mashup software is up against compared to a pro chef, or in this case, a professional music composer,” said Wu. “These pros can get their hands on the original ingredients of a song – the separate vocals, drums, and instruments, known as stems – which lets them mix and match with precision.”

His algorithm takes a different approach, mimicking the process used by professionals. The software works to isolate the stems from each song and identify the most dynamic moments. It adjusts the tempo of the instrumental tracks and adds the drum beat mashup at exactly the right moment for maximum effect.

The result is a unique blend of pleasing lyrics and exciting instrumentals with wide-ranging appeal.

“From what I’ve observed, there’s a clear trend in what listeners prefer in mashups,” said Wu. “Hip-hop drumbeats are the crowd favorite – people seem to really enjoy the groove and rhythm that these beats bring to a mashup.”

Now that the software has been tested on drum tracks, he plans to tackle bass mashups next. For Wu, the dream is to expand the algorithm to incorporate the full instrumental suite and put user-friendly mashup technology directly into the hands of listeners.

“Our ultimate goal is creating an app where users can pick any two songs and choose how to mash them up – whether it’s switching out the drums, bass, instrumentals, or everything together with the other song’s vocals,” said Wu.

Singing in the Rain: Why the Bundengan Sounds Better Wet #Acoustics23

Traditional Indonesian instrument made with bamboo and used by duck herders performs best in the rain.

SYDNEY, Dec. 6, 2023 – A bundengan wears many hats – and is one too. This portable shelter woven from bamboo has protected Indonesian duck herders from the sun and rain for centuries. Able to comfortably balance on the wearer’s head, a bundengan is equipped with a visor that curves around the side to meet at a long back. A more surprising, but no less practical, feature is the collection of strings and bamboo bars added in to produce music. Duck herders fill the hours spent tending to ducks sitting underneath their outfitted shelter, playing their shield as an instrument.

Over the years, bundengan musicians learned that their bamboo music-maker sounds better when played in the rain. Gea Oswah Fatah Parikesit and their team at Universitas Gadjah Mada investigated the physics behind this phenomenon and are presenting their work on the water-dependent acoustic properties of the bundengan Dec. 6 at 10:40 a.m. Australian Eastern Daylight Time, as part of Acoustics 2023, running Dec. 4-8 at the International Convention Centre Sydney.

The bundengan is constructed by weaving bamboo splits, which are covered by overlapping bamboo culm sheaths with ropes to secure everything in place.

“Our team discovered that the key to the sound quality is in the bamboo culm sheaths,” said Parikesit. “To understand the physics of the sheaths, we first had to understand its biological context. When the sheaths were still attached at the bamboo stem, they gradually change shape: First, they are curled because they need to protect the younger parts of the stem, but afterward, they have a more planar shape because they no longer need to protect the older part of the stem.”

When wet, the culm sheaths seek to return to their curled form, but tied down in their planar formation, they instead press into each other. The resulting tension allows the sheaths to vibrate together.

Parikesit will continue investigating the physics of the bamboo culm to develop new musical instruments that, like the bundengan, perform best when wet.

“As an Indonesian, I have extra motivation because the bundengan is a piece of our cultural heritage,” said Parikesit. “I am trying my best to support the conservation and documentation of the bundengan and other Indonesian endangered instruments.”

Picking Up Good Vibrations: The Surprising Physics of the Didjeridu #Acoustics23

Playing Australia’s most iconic instrument requires producing vibrations inside the vocal tract.

SYDNEY, Dec. 6, 2023 – Australia’s most iconic sound is almost certainly the didjeridu. The long wooden tube-shaped instrument is famous for its unique droning music and has played a significant role in Australian Aboriginal culture for thousands of years. Despite the instrument’s simple design, the playing technique can be highly complex.

Joe Wolfe and John Smith from the University of New South Wales conducted acoustic experiments to study the didjeridu’s unusual and complicated performance techniques. Smith will be presenting their work on Dec. 6 at 8:20 a.m. Australian Eastern Daylight Time, as part of Acoustics 2023 Sydney, running Dec. 4-8 at the International Convention Centre Sydney.

“We were interested in the effect of the player’s vocal tract on various wind instruments,” said Smith. “The didjeridu seemed like an obvious start because the effect is so striking.”

Much more than with almost any other instrument, a didjeridu player uses his vocal tract and vocal folds to produce striking changes in timbre.

“Resonances in the mouth tend to remove bands of frequencies in the didjeridu sound and we notice the remaining bands,” said Smith. “It’s a bit like a sculptor removing marble to leave the things that we notice.”

To study didjeridu performance, the team developed new experimental techniques. One involved injecting a broadband acoustic signal into a player’s mouth to measure the acoustic impedance spectrum of a didjeridu player’s vocal tract. The impedance spectrum is an indicator of which frequencies will resonate and which will be suppressed.

This information let Smith and his colleagues identify traits that make the best didjeridus, explore advanced techniques musicians use to create more complicated sounds, and expand their studies to other wind instruments.

In another study, the team were able to identify and understand the acoustic properties of didjeridus most preferred by expert players; these can be very different from the properties of other wind instruments.

“We looked at advanced performance techniques, not only in the didjeridu, but also in other wind instruments, such as clarinet and saxophone,” said Smith. “We continue to research subtle features of expressive playing of wind instruments.”
