Their findings, published this week in Frontiers in Neuroscience, confirm that heart rates become synchronized while the music produces calming effects.

When the choir began to sing — and exhale — in unison, the heart rates slowed down and became entrained, first appearing on the monitor as individual jagged lines, then quickly transforming to fairly uniform waves.

The findings may eventually be used to recommend choral singing for anxiety or pain relief.
