Pure tones have been used by 19th century physicists like Georg Ohm and Hermann von Helmholtz to support theories asserting that the ear functions in a way equivalent to a Fourier frequency analysis. [4] [5] In Ohm's acoustic law, later further elaborated by Helmholtz, musical tones are perceived as a set of pure
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...

The theory behind the illusion was demonstrated during an episode of the BBC's show Bang Goes the Theory, where the effect was described as "a musical barber's pole". [2] The scale as described, with discrete steps between each tone, is known as the discrete Shepard scale.
Traditionally in Western music, a musical tone is a steady periodic sound. A musical tone is characterized by its duration, pitch, intensity (or loudness), and timbre (or quality). [1] The notes used in music can be more complex than musical tones, as they may include aperiodic aspects, such as attack transients, vibrato, and envelope modulation.
Notes may even distinguish the use of different extended techniques by using special symbols. The term note can refer to a specific musical event, for instance when saying the song "Happy Birthday to You", begins with two notes of identical pitch. Or more generally, the term can refer to a class of identically sounding events, for instance when ...
