In music, a note is the representation of a musical sound.
In music, an octave or perfect octave is the interval between one musical pitch and another with double its frequency. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music", the use of which is "common in most musical systems". The interval between the first and second harmonics of the harmonic series is an octave.
In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord.
The slash is the oblique slanting line punctuation mark /. It is also known as a stroke, a solidus, a forward slash or several other historical or technical names including oblique and virgule. Once used to mark periods and commas, the slash is now used to represent division and fractions, exclusive 'or' and inclusive 'or', and as a date separator.
The Mexican peso is the currency of Mexico. Modern peso and dollar currencies have a common origin in the 16th–19th century Spanish dollar, most continuing to use its sign, "$".
In theoretical computer science and cryptography, a trapdoor function is a function that is easy to compute in one direction, yet difficult to compute in the opposite direction without special information, called the "trapdoor". Trapdoor functions are a special case of one-way functions and are widely used in public-key cryptography.
In radio transmission, transmitter power output (TPO) is the actual amount of power of radio frequency (RF) energy that a transmitter produces at its output.
The Namibia dollar has been the currency of Namibia since 1993. It is normally abbreviated with the dollar sign ($), or alternatively N$ to distinguish it from other currencies called “dollar.” It is divided into 100 cents.
In statistics, a k-thpercentile, also known as percentile score or centile, is a score below which a given percentage k of scores in its frequency distribution falls or a score at or below which a given percentage falls. Percentiles are expressed in the same unit of measurement as the input scores, not in percent; for example, if the scores refer to human weight, the corresponding percentiles will be expressed in kilograms or pounds. In the limit of an infinite sample size, the percentile approximates the percentile function, the inverse of the cumulative distribution function.
A power of two is a number of the form 2n where n is an integer, that is, the result of exponentiation with number two as the base and integer n as the exponent.
In cryptography, the Elliptic Curve Digital Signature Algorithm (ECDSA) offers a variant of the Digital Signature Algorithm (DSA) which uses elliptic-curve cryptography.
Nazareth are a Scottish hard rock band formed in Dunfermline in 1968 that had many hit singles and albums in Canada, the United Kingdom, and a number of other European countries beginning in the early 1970s. The breadth of their popularity expanded internationally, including in the United States, with their 1975 album Hair of the Dog, which featured their hits "Hair of the Dog" and a cover of the ballad "Love Hurts". They have continued to record and tour internationally for more than 50 years.
In music, transposition refers to the process or operation of moving a collection of notes up or down in pitch by a constant interval.
The shifting of a melody, a harmonic progression or an entire musical piece to another key, while maintaining the same tone structure, i.e. the same succession of whole tones and semitones and remaining melodic intervals.
Shuffling is a procedure used to randomize a deck of playing cards.
Arohana, Arohanam or Aroha, in the context of Indian classical music, is the ascending scale of notes in a raga. The pitch increases as we go up from Shadja (Sa) to the Taar Shadja (Sa), possibly in a crooked (vakra) manner.
In music theory, an inversion is a type of change to intervals, chords, voices, and melodies. In each of these cases, "inversion" has a distinct but related meaning. The concept of inversion also plays an important role in musical set theory.
"I Love Rock 'n' Roll" is a rock song written by Alan Merrill and Jake Hooker and first recorded by the Arrows, a British rock band, in 1975. A 1981 cover version by Joan Jett & the Blackhearts, released as the first single from her album of the same name, became Jett's highest-charting hit, reaching number one on the Billboard Hot 100 and becoming the No. 3 song for 1982.
