Visit the Music Lab with your baby!

We are now recruiting babies age 2 to 12 months for science research about the world's music. In the study, babies listen to songs while we measure their heart rate, pupil dilation, gaze, motion, and more!

We are conveniently located on Harvard's Cambridge campus, with free parking, and you can take home a Music Lab onesie or other cool prizes as a thank-you gift.
