Sine waves with frequencies in the audio range of 20 Hz to 20 kHz, properly converted to pressure waves in air, can be heard as musical tones. The notes of the musical scale, for the equal tempered scale, are step changes in frequency with the ratio of the twelth root of two, or 1.059463. The sequence of occurence of frequencies is a melodic line. The combination of sine wave of various frequencies is harmonic and chordal structure. If you double the frequency of a sine wave, you get an octave. Triple it and you get an octave and a fifth. Each multiple represents a harmonic, the mixture of which represents timbre. You can also divide the various harmonics by various integers and generate the primary intervals, the minor third, major third, fourth, and fifth. "The Science of Musical Sound", John R. Pierce, Scientific American Library, 1983

What is mussorgsky's musical time period?
He's musical time period was 12 years.
Where did musical toasting come from?
musical toasting came from a long time ago
How did they made the movie of high school musical?
The directors said it was time for a Disney musical to be turned into a movie
What is a tenuto?
A tenuto is a musical articulation mark or musical direction directing that a note or passage is to be held for the full time.
What is the musical term when seven people are singing together at the same time?
A musical group of seven is a "septet."
What is sine waves?
See the link belowA sine wave is computed by a mathematical function. A pure sine wave in a physical sense would exactly match the calculated value in the function at every point in time.
What is the connection between trigonometry ratios and sound waves?
Sound waves are transmitted through a medium as variations in the pressure of the medium. If the variation is plotted as a function of distance (or time), they will generate a sine curve (the cosine curve is the same as a sine curve with a phase shift). In practise, the sine curve is damped: the amplitude (or height) of the oscillations gradually decrease over time or distance, because of attenuation.
What is a complex waveform?
It is a sine wave form coupled with either a DC component or other sine waves or both.The official definition of the word waveform is "a curve showing the shape of a wave at a given time."
What is a good mathematical model for representing transverse waves?
A good mathematical model for representing transverse waves is the sine or cosine function, typically written as y(x,t) = Acos(kx - ω*t), where A is the amplitude, k is the wave number, x is the position, ω is the angular frequency, and t is time. This model describes how the displacement of the wave varies with both position and time.
Which technique uses the echoes of the sound waves to image deep structures in the body?
Ultrasound imaging uses the echoes of sound waves to create images of deep structures in the body. Sound waves are sent into the body, bounce off tissues, and are then detected to create real-time images of organs, muscles, and other structures.
How is a sine curve related to a wave?
A sine curve represents a mathematical function that oscillates in a wave-like pattern. When graphed, it shows a smooth, repetitive wave pattern where the value of the function varies sinusoidally with respect to time or distance. Sine curves are commonly used to represent various types of waves, such as sound waves or electromagnetic waves, as they exhibit similar oscillatory properties.
Can transverse waves resemble a sinusoidal wave?
If you graph the displacement (or some other physical change) over time, you'll quite often get a sine wave.
When two or more waves are at the same place at the same time the resulting effects is called?
When two or more waves are at the same place at the same time, the resulting effect is called interference. Interference can be either constructive, where the waves combine to create a stronger wave, or destructive, where the waves cancel each other out.
What are examples of periodic signals?
Examples of the periodic signals include exponential and sinusoidal signal.
What are two variables of a sine wave?
these are angular velocity & time. Sine(wt)
Why does frequency apply to periodic waves?
Frequency refers to the number of oscillations or cycles that occur in a given time period. In the case of periodic waves, such as sine waves, the frequency is used to describe how often the wave completes one full cycle of oscillation in a specific time frame. This allows us to quantify the rate at which the wave repeats its pattern, which is a fundamental characteristic of periodic waves.
Where to use sine and cosine in physics?
Sine and cosine functions are used in physics to describe periodic phenomena, such as simple harmonic motion, sound waves, and alternating currents in circuits. They help in modeling phenomena that exhibit oscillatory behavior over time or space. Sine and cosine functions are also used in vector analysis to analyze the components of vectors in different directions.
