Using pulse monitors attached to the singers’ ears, the researchers measured the changes in the choir members’ heart rates as they navigated the intricate harmonies of a Swedish hymn. When the choir began to sing, their heart rates slowed down.<\/p>\n

“When you sing the phrases, it is a form of guided breathing,” says musicologist\u00a0Bjorn Vickhoff<\/a>\u00a0of the Sahlgrenska Academy who led the project. “You exhale on the phrases and breathe in between the phrases. When you exhale, the heart slows down.”<\/p>\n

But what really struck him was that it took almost no time at all for the singers’ heart rates to become synchronized. The readout from the pulse monitors starts as a jumble of jagged lines, but quickly becomes a series of uniform peaks. The heart rates fall into a shared rhythm guided by the song’s tempo.<\/p><\/blockquote>\n
