Harmonizing Brain Function

As brain diseases become more prevalent, early assessment of brain function is increasingly vital. This study introduces a piano sight-reading data collection and processing system, along with a quantitative evaluation method for brain health based on spatiotemporal dimensions. The system demonstrated effective data storage and analysis, with speed and ability scores improving over time. At the highest difficulty (D), the right hand outperformed the left in both speed (7% advantage) and ability (8.6% higher score). Over time, Speed scores peaked at 90 for the left hand and 73 for the right, while ability scores reached 96 and 92, respectively. The method showed high sensitivity (92%) and specificity (90%), with positive and negative predictive values of 90.2% and 91.8%, confirming its reliability for detecting cognitive improvement and decline. These findings highlight the potential of musical training for early cognitive assessment and brain health promotion.
