Results

No significant differences were found in correct responses or amylase levels across conditions. The Solfeggio music condition showed lower [Friendliness] (POMS2, p = .04), while [Time Pressure] (NASA-TLX) was lower under general music (p = .02) and tended to decrease with Solfeggio music (p = .05). Only in the Solfeggio condition, amylase changes negatively correlated with [Friendliness] (r = -0.50) and [Vigor-Activity] (r = -0.41).

Baseline Characteristics

A student enrolled in the 4th grade of the School of Rehabilitation at Hyogo Medical University.

Participant flow

The study was conducted after providing participants with a written explanation of the procedure and obtaining their informed consent. Participants performed a simple arithmetic task (Uchida-Kraepelin test) under three conditions: general music (music based on a standard scale tuned to 440 Hz), Solfeggio music, and silence. Salivary amylase levels were measured before and after each task as a physiological stress indicator. Additionally, subjective stress was assessed using the short form of the POMS2 and the NASA-TLX. Comparisons were made between conditions in terms of salivary amylase levels and subjective ratings.
The Uchida-Kraepelin test was administered for 10 minutes under each condition, with at least one day between sessions to minimize carryover effects. Testing was scheduled at approximately the same time of day for each participant to control for circadian variations. The auditory stimuli consisted of two types of music: an original composition in C major at 120 BPM using a standard scale (general music), and a pitch-adjusted version of the same composition incorporating Solfeggio frequencies including 528 Hz (Solfeggio music). The order of condition exposure was counterbalanced across participants.
