| Etymology | The specific epithet “triton” (= tritone in English) represents an interval between peaks of two musical notes that has exactly three whole tones. The so‐called tritone effect is one of the most complex dissonances possible in Occidental Music. During the Middle Ages, this interval was considered lurid and called Diabolus in Musica (“devil in music”). Until the XVIII century, its use in melody was either avoided or severely restricted. The tritone causes a sensation of movement, which makes it highly explored in moments of tension in Classical Music, as in the first movement of Ludwig van Beethoven’s 5th Symphony. In contrast, the tritone is an essential element of pioneering groups of Heavy Metal like Black Sabbath. We named this species in honor for all headbangers and fans of extreme music usually dressed in black like Atractus tritono. |
