In music theory, the hexany is a six-note just intonation scale, with the notes placed on the vertices of an octahedron, equivalently the faces of a cube. The notes are arranged so that every edge of the octahedron joins together notes that make a consonant dyad, and every face joins together the notes of a consonant triad...
Abstract. The sequence of pitches which form a musical melody can be transposed or inverted. Since the 1970s, music theorists have modeled musical transposition and inversion in terms of an action of the dihedral group of order 24. More recently music theorists have found an intriguing second way that the dihedral group of order 24 acts on the set of major and minor triads. We illustrate both geometrically and algebraically how these two actions are dual. Both actions and their duality have been used to analyze works of music as diverse as
Hindemith and the Beatles.
Science News: Cello music that mimics tamarin calls seems to bring forth the same sort of emotions in the monkeys that the original calls would have elicited, researchers report online September 1 in Biology Letters (http://rsbl.royalsocietypublishing.org/content/early/2009/09/01/rsbl.2009.0593.abstract).

PLoS ONE - The communication of stress/anxiety between conspecifics through chemosensory signals has been documented in many vertebrates and invertebrates. Here, we investigate how chemosensory anxiety signals conveyed by the sweat of humans (N = 49) awaiting an academic examination are processed by the human brain, as compared to...
BERLIN (AP) — A bird-bone flute unearthed in a German cave was carved some 35,000 years ago and is the oldest handcrafted musical instrument yet discovered, archaeologists say, offering the latest evidence that early modern humans in Europe had established a complex and creative culture.
