Last year Science Quickly looked across disciplines to piece apart the science of singing. To understand why humans sing, musicologists collaborated on an international study of folk music. To understand how we sing, neuroscientists differentiated how our brain processes speech and singing. Music enthusiast and associate mind and brain editor Allison Parshall takes us through some hallmark 2024 studies that, taken together, piece t...
