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. A simple tone, or pure tone, has a sinusoidal waveform. A complex tone is a combination of two or more pure tones that have a periodic pattern of repetition, unless specified otherwise.
A bracket is used to connect two or more lines of music that sound simultaneously. In contemporary usage it usually connects staves of individual instruments (e.g., flute and clarinet ; two trumpets ; etc.) or multiple vocal parts, whereas the brace connects multiple parts for a single instrument (e.g., the right-hand and left-hand staves of a ...
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 tones.
The term Grand ballabile is used if nearly all participants (including principal characters) of a particular scene in a full-length work perform a large-scale dance. bar , or measure unit of music containing a number of beats as indicated by a time signature ; also the vertical bar enclosing it
The Italian term 'dal segno' literally means 'from the sign.' In most music you will see either D.S. al Fine (which means 'go back to the 𝄋 sign and play the music again until you come to the bar marked Fine, then stop') or D.S. al Coda (which means 'go back to the 𝄋 sign and play the music again until you come to the bar marked To Coda ...
The sum (blue) of two sine waves (red, green) is shown as one of the waves increases in frequency. The two waves are initially identical, then the frequency of the green wave is gradually increased by 25%. Constructive and destructive interference can be seen.

In mathematics, sine and cosine are trigonometric functions of an angle.The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that ...
