E♭ (musical Note)
E (E-flat) or mi bémol is the fourth semitone of the solfège. It lies a diatonic semitone above D and a chromatic semitone below E, thus being enharmonic to D ( D-sharp) or ''re dièse''. In equal temperament it is also enharmonic with F (F-double flat). However, in some temperaments, D is not the same as E. E is a perfect fourth above B, whereas D is a major third above B. When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the E above middle C (or E4) is approximately 311.127 Hz. See pitch (music) for a discussion of historical variations in frequency. In German nomenclature, it is known as Es, sometimes (especially in the context of musical motifs, e.g. DSCH motif) abbreviated to S. Designation by octave Scales Common scales beginning on E * E major: E F G A B C D E * E natural minor: E F G A B C D E * E harmonic minor: E F G A B C D E * E melodic minor ascending: E F G A B C D E * E melodic minor descending: E ...

Semitone
A semitone, also called a half step or a half tone, is the smallest musical interval commonly used in Western tonal music, and it is considered the most dissonant when sounded harmonically. It is defined as the interval between two adjacent notes in a 12-tone scale. For example, C is adjacent to C; the interval between them is a semitone. In a 12-note approximately equally divided scale, any interval can be defined in terms of an appropriate number of semitones (e.g. a whole tone or major second is 2 semitones wide, a major third 4 semitones, and a perfect fifth 7 semitones. In music theory, a distinction is made between a diatonic semitone, or minor second (an interval encompassing two different staff positions, e.g. from C to D) and a chromatic semitone or augmented unison (an interval between two notes at the same staff position, e.g. from C to C). These are enharmonically equivalent when twelve-tone equal temperament is used, but are not the same thing in meantone temper ...

Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its freq ...

Phrygian Mode
The Phrygian mode (pronounced ) can refer to three different musical modes: the ancient Greek ''tonos'' or ''harmonia,'' sometimes called Phrygian, formed on a particular set of octave species or scales; the Medieval Phrygian mode, and the modern conception of the Phrygian mode as a diatonic scale, based on the latter. Ancient Greek Phrygian The octave species (scale) underlying the ancient-Greek Phrygian ''tonos'' (in its diatonic genus) corresponds to the medieval and modern Dorian mode. The terminology is based on the '' Elements'' by Aristoxenos (fl. c. 335 BC), a disciple of Aristotle. The Phrygian ''tonos'' or ''harmonia'' is named after the ancient kingdom of Phrygia in Anatolia. In Greek music theory, the ''harmonia'' given this name was based on a ''tonos'', in turn based on a scale or octave species built from a tetrachord which, in its diatonic genus, consisted of a series of rising intervals of a whole tone, followed by a semitone, followed by a whole tone. : In ...

Dorian Mode
Dorian mode or Doric mode can refer to three very different but interrelated subjects: one of the Ancient Greek ''harmoniai'' (characteristic melodic behaviour, or the scale structure associated with it); one of the medieval musical modes; or—most commonly—one of the modern modal diatonic scales, corresponding to the piano keyboard's white notes from D to D, or any transposition of itself. : Greek Dorian mode The Dorian mode (properly ''harmonia'' or ''tonos'') is named after the Dorian Greeks. Applied to a whole octave, the Dorian octave species was built upon two tetrachords (four-note segments) separated by a whole tone, running from the ''hypate meson'' to the ''nete diezeugmenon''. In the enharmonic genus, the intervals in each tetrachord are quarter tone–quarter tone–major third. : In the chromatic genus, they are semitone–semitone–minor third. : In the diatonic genus, they are semitone–tone–tone. : In the diatonic genus, the sequence over the ...

Ionian Mode
Ionian mode is a musical mode or, in modern usage, a diatonic scale also called the major scale. It is the name assigned by Heinrich Glarean in 1547 to his new authentic mode on C (mode 11 in his numbering scheme), which uses the diatonic octave species from C to the C an octave higher, divided at G (as its dominant, reciting tone/reciting note or ''tenor'') into a fourth species of perfect fifth (tone–tone–semitone–tone) plus a third species of perfect fourth (tone–tone–semitone): C D E F G + G A B C. This octave species is essentially the same as the major mode of tonal music. Church music had been explained by theorists as being organised in eight musical modes: the scales on D, E, F, and G in the "greater perfect system" of "musica recta," each with their authentic and plagal counterparts. Glarean's twelfth mode was the plagal version of the Ionian mode, called Hypoionian (under Ionian), based on the same relative scale, but with the major third as its ''tenor' ...

Diatonic Scale
In music theory, a diatonic scale is any heptatonic scale that includes five whole steps (whole tones) and two half steps (semitones) in each octave, in which the two half steps are separated from each other by either two or three whole steps, depending on their position in the scale. This pattern ensures that, in a diatonic scale spanning more than one octave, all the half steps are Maximal evenness, maximally separated from each other (i.e. separated by at least two whole steps). The seven pitch (music), pitches of any diatonic scale can also be obtained by using a Interval cycle, chain of six perfect fifths. For instance, the seven natural (music), natural pitch classes that form the C-major scale can be obtained from a stack of perfect fifths starting from F: :F–C–G–D–A–E–B Any sequence of seven successive natural notes, such as C–D–E–F–G–A–B, and any Transposition (music), transposition thereof, is a diatonic scale. Modern musical keyboards are des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minor Scale
In music theory, the minor scale is three scale patterns – the natural minor scale (or Aeolian mode), the harmonic minor scale, and the melodic minor scale (ascending or descending) – rather than just two as with the major scale, which also has a harmonic form but lacks a melodic form. In each of these scales, the first, third, and fifth scale degrees form a minor triad (rather than a major triad, as in a major scale). In some contexts, ''minor scale'' is used to refer to any heptatonic scale with this property (see Related modes below). Natural minor scale Relationship to relative major A natural minor scale (or Aeolian mode) is a diatonic scale that is built by starting on the sixth degree of its relative major scale. For instance, the A natural minor scale can be built by starting on the 6th degree of the C major scale: : Because of this, the key of A minor is called the ''relative minor'' of C major. Every major key has a relative minor, which starts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E-flat Minor
E-flat minor is a minor scale based on E, consisting of the pitches E, F, G, A, B, C, and D. Its key signature consists of six flats. Its relative key is G-flat major (or enharmonically F-sharp major) and its parallel key is E-flat major. Its enharmonic equivalent, D-sharp minor, contains the same number of sharps. The E-flat natural minor scale is: : Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The E-flat harmonic minor and melodic minor scales are: : : Music in E-flat minor In the 24 canonic keys, most of the composers preferred E-flat minor, while Johann Sebastian Bach, Sergei Lyapunov, and Manuel Ponce preferred D-sharp minor. In Book 1 of ''The Well-Tempered Clavier'' by Bach, Prelude No. 8 is written in E-flat minor while the following fugue is written in D-sharp minor. In Book 2, both movements are in D-sharp minor. Haydn's Piano Trio No. 41, H. XV.31 in two movements, composed in 1794/95 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E-flat Major
E-flat major (or the key of E-flat) is a major scale based on E, consisting of the pitches E, F, G, A, B, C, and D. Its key signature has three flats. Its relative minor is C minor, and its parallel minor is E minor, (or enharmonically D minor). The E-flat major scale is: : Characteristics The key of E-flat major is often associated with bold, heroic music, in part because of Beethoven's usage. His ''Eroica Symphony'', ''Emperor Concerto'' and ''Grand Sonata'' are all in this key. Beethoven's (hypothetical) 10th Symphony is also in E-flat. But even before Beethoven, Francesco Galeazzi identified E-flat major as "a heroic key, extremely majestic, grave and serious: in all these features it is superior to that of C." Three of Mozart's completed Horn Concertos and Joseph Haydn's Trumpet Concerto are in E-flat major, and so is Anton Bruckner's Fourth Symphony with its prominent horn theme in the first movement. Another notable heroic piece in the key of E-flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helmholtz Pitch Notation
Helmholtz pitch notation is a system for naming musical notes of the Western chromatic scale. Fully described and normalized by the German scientist Hermann von Helmholtz, it uses a combination of upper and lower case letters (A to G), and the sub- and super-prime symbols ( ͵ ′ or ) to denote each individual note of the scale. It is one of two formal systems for naming notes in a particular octave, the other being scientific pitch notation. History Helmholtz proposed this system in order to accurately define pitches in his classical work on acoustics ''Die Lehre von den Tonempfindungen als physiologische Grundlage für die Theorie der Musik'' (1863) translated into English by A.J. Ellis as ''On the Sensations of Tone'' (1875). Helmholtz based his notation on the practice of German organ builders for labelling their pipes, itself derived from the old German organ tablature in use from late medieval times until the early 18th century. His system is widely use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Pitch Notation
Scientific pitch notation (SPN), also known as American standard pitch notation (ASPN) and international pitch notation (IPN), is a method of specifying musical Pitch (music), pitch by combining a musical Note (music), note name (with accidental (music), accidental if needed) and a number identifying the pitch's octave. Although scientific pitch notation was originally designed as a companion to scientific pitch (see below), the two are not synonymous. Scientific pitch is a pitch standard—a system that defines the specific frequencies of particular pitches (see below). Scientific pitch notation concerns only how pitch names are notated, that is, how they are designated in printed and written text, and does not inherently specify actual frequencies. Thus, the use of scientific pitch notation to distinguish octaves does not depend on the pitch standard used. Nomenclature The notation makes use of the traditional tone names (A to G) which are followed by numbers showing which octa ...

DSCH Motif
DSCH is a musical motif used by the composer Dmitri Shostakovich to represent himself. It is a musical cryptogram in the manner of the BACH motif, consisting of the notes ''D, E-flat, C, B natural'', or in German musical notation ''D, Es, C, H'' (pronounced as "De-Es-Ce-Ha"), thus standing for the composer's initials in German transliteration: ''D. Sch.'' (Dmitri Schostakowitsch). Usage By Shostakovich The motif occurs in many of his works, including: * Symphony No. 8 in C minor, Op. 65 * Violin Concerto No. 1 in A minor, Op. 77 * Fugue No. 15 in D-flat major, Op. 87 (only once, in the stretto) * String Quartet No. 5 in B-flat major, Op. 92 * Symphony No. 10 in E minor, Op. 93 * String Quartet No. 6 in G major, Op. 101 (Played all at once by the four instruments at the end of each movement) * Cello Concerto No. 1 in E flat major, Op. 107 * String Quartet No. 8 in C minor, Op. 110 (appears in every single movement) * Symphony No. 15 in A major, Op. 141. * Piano Sonata No. ...
