One of the scholars who is frequently cited in articles that promote how everyone should sing is the late Professor Stephen Demorest of Northwestern University. He has conducted some of the most prominent research studies demonstrating how singing is a learnable skill and is not as dependent on "talent" as we are often led to believe. Importantly, his research also highlights how singing skills take practice to maintain (just like speaking a second language, doing a backflip, etc.) or we risk succumbing to the "use it or lose it" phenomenon.
The pertinent research was published in the journal Music Perception, and is summarized in an article in the Northwestern News. In the study, investigators compared the singing accuracy of kindergarteners, sixth graders, and college students. They found there was significant improvement in students' skills from kindergarten to sixth grade, which—go figure—is when most students are getting some sort of consistent music instruction in school. From sixth grade to college, however, students regressed in their abilities and were only singing as accurately as the kindergarteners in the study.
As the article describes, the years between sixth grade and the end of high school (when their singing abilities started to decline) are when most children experience voice changes due to puberty (it doesn't receive as much attention, but it's worth noting that children who experience an estrogen-dominant puberty, as opposed to a testosterone-dominant puberty, also experience significant voice changes during those years). I suspect the vocal instabilities of adolescence and the heightened self-consciousness that coincides with that time of life cause many students to stop singing around that time—or at least to stop singing in front of others.
Of course, a lot of students that age simply choose to focus their energies in other areas, since those are also the years when they start filling their schedules with sports, AP classes, and other activities that place demands on their time. The arts, music, and singing often get left behind. As Demorest points out in the article, by eighth grade, only 34% of children in the United States participate in elective music instruction, and that number declines even more by the time students reach high school graduation.
I think we all understand that if someone trains as a figure skater from kindergarten through sixth grade, and then stops, that person will not be as good a skater by the time they get to college. Logically, this applies to singing, as well.
Of course, the other noteworthy results that come out of Demorest's research is how it highlights the psychological baggage we bring to singing that we don't bring into other activities. As mentioned in the article, children who have been told that they can’t sing are less likely to engage with music throughout life. Many of them carry painful memories—like being called "tone deaf"—well into adulthood.
As Demorest states, “Everyone should be able to have music as a part of their life. It’s OK to select out of it, but it should be by choice, rather than because you think you don’t have ‘talent.' And if at any point in life you decide to become more engaged, you can be...When people are unsuccessful [at singing] they take it very personally, but we think if you sing more, you’ll get better.”
One way Demorest suggests people can continue to use their voices regularly is to have low-stakes opportunities in music that don’t require the commitment of time that playing in a band or an orchestra does. “People need a place to sing and have fun without worrying about how good they are,” he said.
I would argue that even those of us who have professional aspirations as vocalists need these sorts of low-stakes opportunities to sing. Focused practice is obviously crucial for building specific skills, but recreational singing, or just jamming out with friends, is also allowed to be part of your vocal exercise (actually, it's encouraged).
How has your practice been this week? Do you need more low-stakes opportunities to sing with others? How can you add that to your life?
Now go practice.
