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."
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.
When two or more waves are at the same place at the same time the resulting effects is called?
I believe you're describing "interference." But I can't be sure with the way you've phrased the question. If you're referring to sound waves, then when two sine waves of equal amplitude and frequency occupy the same space and time, but are at opposite points in their (sine) oscillation, they will interfere perfectly and cancel one another out. However, if those two waves were in the exact same space and time, and at the exact same point in their sine pattern/oscillation, then they would exhibit "constructive interference," and the amplitude of the of the new wave would be the sum of the amplitudes of the two original contributing waves (minus something negligible due to physical constraints)--the frequency would remain constant.
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.
What are two variables of a sine wave?
these are angular velocity & time. Sine(wt)
Why do you use T for period in trigonometry?
Simple harmonic motion - such as the motion of a simple pendulum, electromagnetic and other waves, tidal heights - may be modelled as sine (or cosine) curves. In these cases, the periodicity of the function is measured in units of time.
What is the frequency of a sine wave that has a cycle time of 1ms?
1kHz
How many degrees are the current and voltage out of phase with each other in a pure resistive circuit?
The voltage and current sine waves cross the zero line at the same time and going in the same direction. The phase angle is 0°. They are said to be in-phase.
When was The Happy Time - musical - created?
The Happy Time - musical - was created in 1965.
What is an analog signal and a digital signal?
An analog signal is one which is continuous in time as well as continuous in amplitude . Example : sine wave, cosine wave. An Digital signal is one which is continuous in discrete in time. Example : square waves.
