  Music plays a huge part in shaping peoples' psychology and behavioral
patterns. This paper investigates the connection between national anthems and
different global indices with computational music analysis and statistical
correlation analysis. We analyze national anthem musical data to determine
whether certain musical characteristics are associated with peace, happiness,
suicide rate, crime rate, etc. To achieve this, we collect national anthems
from 169 countries and use computational music analysis techniques to extract
pitch, tempo, beat, and other pertinent audio features. We then compare these
musical characteristics with data on different global indices to ascertain
whether a significant correlation exists. Our findings indicate that there may
be a correlation between the musical characteristics of national anthems and
the indices we investigated. The implications of our findings for music
psychology and policymakers interested in promoting social well-being are
discussed. This paper emphasizes the potential of musical data analysis in
social research and offers a novel perspective on the relationship between
music and social indices. The source code and data are made open-access for
reproducibility and future research endeavors. It can be accessed at
