Overtone series
The overtone series, also known as the harmonic series, is a sequence of frequencies that are integer multiples of a fundamental frequency, and is a fundamental concept in Music theory, Acoustics, and Physics. The series is characterized by a sequence of frequencies that are harmonically related to the fundamental frequency, with each successive frequency being an integer multiple of the previous one. This series is important in understanding the Material properties of musical instruments and the perception of Sound.
The overtone series is used in various musical traditions, including Persian literature and Music theory, to create harmonically rich and complex sounds. It is also related to the concept of Equal temperament, which is a system of tuning used in Western music. The study of the overtone series has also led to a deeper understanding of Neuromuscular control and Animal Intelligence, particularly in the context of Sound perception and production.
