We report a statistical analysis of more than eight thousand songs. Specifically, we investigated the probability distribution of the normalized sound amplitudes. Our findings suggest a universal form of distribution that agrees well with a one-parameter stretched Gaussian. We also argue that this parameter can give information on music complexity, and consequently it helps classify songs as well as music genres. Additionally, we present statistical evidence that correlation aspects of the…

TLDR
The existing literature is reviewed, focusing on culinary, visual, musical and literary arts, as well as on the connections between physics and the social sciences in general, showing that the synergies between these fields yield highly entertaining results that can often be enjoyed by layman and experts alike.

The Topos of Music III: Gestures

TLDR
The structure of a group itself is a new type of configuration, which can be studied and classified, and represented as itself, in this general study of groups, and it is considered that projective modules over commutative rings are like vector bundles on compact spaces.

Long-range spatial correlations and fluctuation statistics of lightning activity rates in Brazil

We report on a statistical analysis of the lightning activity rates in all Brazilian cities. We find out that the average of lightning activity rates exhibits a dependence on the latitude of the

Non-Gaussian center-of-pressure velocity distribution during quiet stance

In the present study, we investigate patterns in the postural sway that characterize the static balance in human beings. To measure the postural sway, sixteen healthy young subjects performed quiet

A Complexity-Based Approach for the Detection of Weak Signals in Ocean Ambient Noise

TLDR
The simulation results indicate that the complexity is sensitive to change in the information in the ambient noise and the change in SNR, a finding that enables the detection of weak ship signals in strong background ambient noise.
