Circle Singing as an Inclusive Educational Practice for English Pronunciation in Higher Education
This quasi-experimental study at Roma Tre University demonstrates that a 15-hour Circle Singing intervention significantly improves English pronunciation accuracy among higher education students compared to a control group, while also fostering engagement and confidence.

Imagine your brain as a super-complex orchestra. For a long time, scientists thought the musicians playing "music" and the ones playing "language" were in totally different rooms, practicing different songs. But recently, researchers have discovered that these musicians actually share the same practice hall. They use the same tools to listen to pitch, keep time, and remember patterns. It turns out that training your brain to be a precise musician might actually make you a better speaker, too. This idea is built on a theory called the "OPERA hypothesis," which suggests that if you practice music with enough Overlap (using the same brain parts), Precision (being super accurate), Emotion (having fun), Repetition (doing it a lot), and Attention (focusing hard), your brain will get better at handling language sounds. So, the big question for teachers and students is: Can we use the joy of singing together to fix the tricky business of speaking a foreign language?
This is exactly what a team of researchers at Roma Tre University wanted to find out. They set up a fun experiment involving 188 university students to see if a practice called "Circle Singing" could help people speak English more accurately. Circle Singing is like a musical game where a group stands in a circle, and a leader teaches them short, catchy musical patterns with English words. The group then layers these patterns on top of each other, creating a beautiful, complex harmony where everyone has to listen closely and stay in sync. The researchers wondered: If you spend 15 hours doing this, will your English pronunciation get better?
To test this, they split the students into two groups. The "Experimental Group" (104 students) spent 15 hours in the Circle Singing lab, while the "Control Group" (84 students) just went about their normal lives without any special singing lessons. It is important to note that because the students were not randomly assigned to these groups, the two groups were not exactly the same to begin with. In fact, the singing group started the study with a noticeably higher average score than the control group. Before and after the 15 hours, everyone took a test using a smart computer program called SpeechAce. This program listens to you speak English sentences and gives you a score from 1 to 100 based on how accurately you pronounce the sounds.
The results were pretty clear and quite exciting. The students who didn't sing anything actually got slightly worse at the test, dropping their average score from 78.830 to 77.676. It's like if you stopped practicing your instrument for a few months and your fingers got a little stiff. But the group that did the Circle Singing? They soared. Their average score jumped from 82.986 all the way up to 89.498. The math shows that this wasn't just a lucky fluke; the difference between the two groups was huge and statistically significant. The singing group improved because they were constantly listening, matching pitches, and repeating English sounds in a rhythmic, emotional, and social way.
The paper suggests that this method works because it forces your brain to do a lot of heavy lifting at once. You aren't just memorizing words; you are coordinating your voice, your ears, and your memory while having fun with friends. The students themselves reported feeling more confident and engaged. However, the researchers are careful to point out a few limits: since the control group didn't do an alternative activity (like a different kind of group game), we can't be 100% sure the improvement came only from the singing itself rather than just being part of a fun group activity. Despite these caveats, the study strongly suggests that turning English class into a group singing circle could be a powerful, inclusive way to help university students master the sounds of a new language. It's a reminder that sometimes, the best way to learn to speak is to learn to sing.
