A pure tone's pressure waveform versus time looks like this; its frequency determines the x axis scale; its amplitude determines the y axis scale; and its phase determines the x origin. In psychoacoustics , a pure tone is a sound with a sinusoidal waveform ; that is, a sine wave of constant frequency , phase-shift , and amplitude . [ 1 ]
A musical scale is a discrete set of pitches used in making or describing music. The most important scale in the Western tradition is the diatonic scale but many others have been used and proposed in various historical eras and parts of the world.
The time value of money is the idea that receiving a given amount of money today is more valuable than receiving the same amount in the future due to its potential earning capacity. If you invest ...
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 ...
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 ...
Ptolemy used chord length to define his trigonometric functions, a minor difference from the sine convention we use today. [12] (The value we call sin(θ) can be found by looking up the chord length for twice the angle of interest (2θ) in Ptolemy's table, and then dividing that value by two.)
The displacement of an undamped spring-mass system oscillating around the equilibrium over time is a sine wave. Sinusoids that exist in both position and time also have: a spatial variable x {\displaystyle x} that represents the position on the dimension on which the wave propagates.
