Each session consisted of 20 min’ listening. Both sessions used the same music (movie soundtracks) but tuned to 440 Hz on one day and 432 Hz on the other. Interventions: Two sessions of music listening on different days. Participants: 33 volunteers, not suffering from acute and/or chronic diseases. Setting: A room dedicated to listening to music, in an Italian city. Objective: To identify differences in vital parameters and perceptions after listening to music at different frequencies, 440 Hz versus 432 Hz. Some theorists and musicians claim that the 432 Hz tuning has better effects on the human body, but there are no scientific studies that support this hypothesis. Context: The current reference frequency for tuning musical instruments is 440 Hz.
