Three days, one song: BYU music students team up with Grammy winner Mark Lettieri to create new track
Imagine being tasked with writing a song in just three days, and then getting the chance to work alongside world-renowned guitarist Mark Lettieri. That was the incredible opportunity five BYU commercial music students experienced earlier this year.
Inside the music building’s new state-of-the-art recording studio, a nervous excitement was palpable.
BYU commercial music students Carson Ripley, Kieran Hellum, Hannah Eyre, Michelle Cheuk, Kevin West and world-renowned guitarist Mark Lettieri had one task: create a brand-new track in three days.
Lettieri, a five-time Grammy winner, was in Provo to perform as part of the BRAVO! series. While in town, he agreed to write and record a single with BYU students. He offered a keen musical ear and created a supportive atmosphere that challenged the students to take creative risks and stretch their abilities. His encouragement kept them motivated.
“The passion from these students has been really inspiring,” Lettieri noted after three intense days and dozens of jam sessions. “I’m very impressed with their growth and how well they work together.”
After the initial shock of working with a musician of Lettieri’s caliber wore off, the students took advantage of the real-world experience as they created a song from scratch. They learned lessons of teamwork and improvisation, skills vital in any collaborative music project.
“Collaborating with Mark Lettieri has been one of the most educational, terrifying, and exciting experiences I’ve had at BYU,” said senior vocalist Hannah Eyre. “He’s so professional but also a lot of fun to work with. He always lifted us up and helped us feel confident in our ideas.”
Writing a song can take months or even years, but Lettieri and the students brought their song to life in less than 72 hours. Finding a cohesive sound was key, and channeling the groups’ collective creative energy was akin to harmonizing a complex chord.
“Once we came up with a groovy bassline, everything started locking into place,” Eyre explained. “On the second day, we changed the feel of the chorus, and when we started layering melodies and vocals, it really started to come together.” Their collaboration was a true team effort, with each member contributing their strengths.
The final product is a song titled “Two Worlds, One City,” which explores the complexities of a couple trying to articulate their feelings. The soulful pop piece reflects the emotional depth and challenges of relationships.
And it’s catchy.
The BYU team of students say they’re walking away with more than just a song; they’ve gained valuable experience that will influence their future musical endeavors. Additionally, they’ve found connection, meaning and a sense of belonging at BYU.
“Being asked to be part of this project really helped me feel like I was part of this program and a priority to this program,” said Eyre. “BYU places such importance on giving its students the best experience that we can. And I believe at this institution I’ve had that. These opportunities I’ve had are some of the coolest opportunities in the world and I haven’t had to leave my campus.”
The BYU commercial music program is widely regarded as a top program, producing graduates that are creating music for media, soundtracks and contemporary productions. Under the guidance of Ron Saltmarsh, the program offers students hands-on opportunities to learn from real-world musicians while working in state-of-the-art facilities.
“I never had access to a world class studio as a college guitarist,” said Lettieri. “These students are getting an education that is very practical. In today’s music business, you have to know how to do a lot of things. So it’s good that they’re getting such a diverse education.”

![Life and Breath: BYU-Nepali Team Studies Air Pollutions Human Impact
With each breath, brick workers in Nepal’s Kathmandu Valley inhale dangerous particulates. From hazardous aerosols released during the brickmaking process and indoor cooking to emissions from vehicles and factories that seep into their homes, air pollution in the region is inescapable.
Concerned about the effects of these exposures, an interdisciplinary BYU team recently came together to conduct a research study in Nepal, aiming to measure brick workers’ exposure to pollutants and to assess their respiratory health. The eventual goal is to determine what information, technology and strategies they can develop with the Nepali people to help them improve their well-being.
Air pollution “lives with them every day, at the brick kiln, when they’re awake, when they’re asleep, when they’re working, when they’re home, said BYU public health professor Jim Johnston, who led the group of more than two dozen researchers.
The researchers were particularly concerned by brick workers’ exposure to PM2.5, particulate matter less than 2.5 micrometers in diameter, small enough to bypass the respiratory system’s defenses and get into the gas-exchange region of the lungs. The team also wanted to determine workers’ exposure to silica dust, another respiratory hazard, at the brick kilns.
To get the information they needed, the BYU group drew from their many areas of expertise, as well as that of their collaborators from the University of Utah, Kathmandu University and the Karnali Academy of Health Sciences, and local Nepali leadership.
BYU faculty and students in nutrition, dietetics and food sciences performed health assessments for the 50 or so brick workers that participated in the study, examining their vitals, diet and lung function. The nursing team collected saliva and blood samples and used a novel method of pulmonary ultrasound to look for evidence of inflammation in the lungs.
To get information about each worker’s exposure to PM2.5 and silica-containing dust as they moved throughout the day — previous research has used only stationary monitoring of an area — the public health group fitted the workers with air pollution monitors they wore for 24 hours.
Cell biologists in the group analyzed blood serum to determine how PM2.5 and silica exposures impacted inflammatory responses among the workers. Meanwhile, BYU engineers assessed community development challenges, looking at infrastructure, housing, farming practices, community leadership structures and the quality of water, soil and air in the region.
“We all have a common goal, and our unique ways of learning are creating this big-picture effect,” said nursing student Symbria Lewis.
BYU faculty and students anticipate future trips to Nepal to continue the research, which promises to be beneficial for BYU as well as the Nepali people.
“I’m enthusiastic and very happy to work with BYU,” added Seshananda Sanjel, a professor at the Karnali Academy of Health Sciences in Nepal. “The Nepali government doesn’t have the funding [we need] for research, [so] with this collaboration we can do many more things, and I expect this collaboration will go for many years.”
“I don’t know that I’ve ever seen my students so happy and so engaged in learning,” Johnston said. “It’s been incredibly rewarding to just sit back and listen to them talk about the experiences they’re having here, their love for the people, their desire to use the science to make the world a better place. It’s like the lights have come on.”
