Prelude And Fugue In C Major, BWV 846
The Prelude and Fugue in C major, Bach-Werke-Verzeichnis, BWV 846, is a keyboard composition written by Johann Sebastian Bach. It is the first prelude and fugue in the first book of ''The Well-Tempered Clavier'', a series of 48 preludes and fugues by the composer. An early version of the prelude, BWV 846A, is found in the ''Klavierbüchlein für Wilhelm Friedemann Bach''. Analysis Prelude The prelude (music), prelude is 35 bars long and consists mostly of broken chords. Below are the first four bars of the prelude: : The prelude continues like this with different variations on harmony and Key change, change of key. The prelude ends with a single C major chord. Fugue The fugue is 27 bars long and is written for Four-part harmony, four voices. It starts with a two-measure Subject (music), subject in the alto voice.

Hermann Keller
Hermann Keller (20 November 1885 – 17 August 1967) was a German Protestant church musician and musicologist. Life Born in Stuttgart the son of an architect, he followed his father's profession by also studying architecture in Stuttgart and Munich. During his studies he became a member of the Stuttgart " Swabia" in 1903. Max Reger, with whom Keller took private lessons, advised him to make music his profession. Keller followed this advice and thereupon studied additionally in Munich, Stuttgart and Leipzig. From 1910 he worked as a teacher at the Hochschule für Musik Franz Liszt, Weimar, Grand Ducal Music School and organist at the Stadtkirche in Weimar. In 1916, however, he moved back to his home town of Stuttgart, where he worked as organist at the Markuskirche (Stuttgart), Markuskirche. (1916), lecturer at the Technical College (1919), teacher at the College of Music (1920) as well as head of its department for church and school music (1928-1933). After the Second World War, h ...

Diatonic Function
In music, function (also referred to as harmonic function) is a term used to denote the relationship of a chord"Function", unsigned article, ''Grove Music Online'', . or a scale degree to a tonal centre. Two main theories of tonal functions exist today: * The German theory created by Hugo Riemann in his ''Vereinfachte Harmonielehre'' of 1893, which soon became an international success (English and Russian translations in 1896, French translation in 1899), and which is the theory of functions properly speaking."It was Riemann who coined the term 'function' in ''Vereinfachte Harmonielehre'' (1893) to describe relations between the dominant and subdominant harmonies and the referential tonic: he borrowed the word from mathematics, where it was used to designate the correlation of two variables, an 'argument' and a 'value'". Brian Hyer, "Tonality", ''Grove Music Online'', . Riemann described three abstract tonal "functions", tonic, dominant and subdominant, denoted by the letters ...

Major Second
In Western music theory, a major second (sometimes also called whole tone or a whole step) is a second spanning two semitones (). A second is a musical interval encompassing two adjacent staff positions (see Interval number for more details). For example, the interval from C to D is a major second, as the note D lies two semitones above C, and the two notes are notated on adjacent staff positions. Diminished, minor and augmented seconds are notated on adjacent staff positions as well, but consist of a different number of semitones (zero, one, and three). The major second is the interval that occurs between the first and second degrees of a major scale, the tonic and the supertonic. On a musical keyboard, a major second is the interval between two keys separated by one key, counting white and black keys alike. On a guitar string, it is the interval separated by two frets. In moveable-do solfège, it is the interval between ''do'' and ''re''. It is considered a melo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enharmonic
In modern musical notation and tuning, an enharmonic equivalent is a note, interval, or key signature that is equivalent to some other note, interval, or key signature but "spelled", or named differently. The enharmonic spelling of a written note, interval, or chord is an alternative way to write that note, interval, or chord. The term is derived from Latin ''enharmonicus'', from Late Latin ''enarmonius'', from Ancient Greek ἐναρμόνιος (''enarmónios''), from ἐν (''en'') and ἁρμονία (''harmonía''). Definition For example, in any twelve-tone equal temperament (the predominant system of musical tuning in Western music), the notes C and D are ''enharmonic'' (or ''enharmonically equivalent'') notes. Namely, they are the same key on a keyboard, and thus they are identical in pitch, although they have different names and different roles in harmony and chord progressions. Arbitrary amounts of accidentals can produce further enharmonic equivalents, such as B (me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harmonic Minor
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 on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parallel Key
In music theory, a major scale and a minor scale that have the same tonic note are called parallel keys and are said to be in a parallel relationship. Forte, Allen (1979). ''Tonal Harmony'', p.9. 3rd edition. Holt, Rinehart, and Wilson. . "When a major and minor scale both begin with the same note ... they are called ''parallel''. Thus we say that the parallel major key of C minor is C major, the parallel minor of C major is C minor." The parallel minor or tonic minor of a particular major key is the minor key based on the same tonic; similarly the parallel major has the same tonic as the minor key. For example, G major and G minor have different modes but both have the same tonic, G; so G minor is said to be the parallel minor of G major. In contrast, a major scale and a minor scale that have the same key signature (and therefore different tonics) are called relative keys. A major scale can be transformed to its parallel minor by lowering the third, sixth, and seventh scale ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borrowed Chord
A borrowed chord (also called mode mixture,Romeo, Sheila (1999). ''Complete Rock Keyboard Method: Mastering Rock Keyboard'', p. 42. . Bouchard, Joe and Romeo, Sheila (2007). ''The Total Rock Keyboardist'', p. 120. Alfred Music. . modal mixture, substituted chord,White, William Alfred (1911). Harmonic Part-writing', p. 42. Silver, Burdett, & Co. . modal interchange, or mutation) is a chord (music), chord borrowed from the parallel key (minor scale, minor or major scale with the same tonic (music), tonic). Borrowed chords are typically used as "color chords", providing harmonic variety through contrasting scale forms, which are major scales and the three forms of minor scales.Benward & Saker (2009), p. 71. Chords may also be borrowed from other parallel musical mode, modes besides the major and minor mode, for example D Dorian mode, Dorian with D major. The mixing of the major and minor modes developed in the baroque music, Baroque period. Borrowed chords are distinguished from mod ...

Root (chord)
In music theory, the concept of root is the idea that a chord (music), chord can be represented and named by one of its Musical note, notes. It is linked to Harmony (music), harmonic thinking—the idea that vertical aggregates of notes can form a single unit, a chord. It is in this sense that one speaks of a "C chord" or a "chord on C"—a chord built from C and of which the note (or pitch) C is the root. When a chord is referred to in Classical music or popular music without a reference to what type of chord it is (either major or minor, in most cases), it is assumed a major triad, which for C contains the notes C, E and G. The root need not be the bass note, the lowest note of the chord: the concept of root is linked to that of the Inverted chord, inversion of chords, which is derived from the notion of Invertible Counterpoint, invertible counterpoint. In this concept, chords can be inverted while still retaining their root. In tertian harmonic theory, wherein chords can be con ...

Minor Chord
In music theory, a minor chord is a chord that has a root, a minor third, and a perfect fifth. When a chord comprises only these three notes, it is called a minor triad. For example, the minor triad built on C, called a C minor triad, has pitches C–E–G: In harmonic analysis and on lead sheets, a C minor chord can be notated as Cm, C−, Cmin, or simply the lowercase "c". A minor triad is represented by the integer notation . A minor triad can also be described by its intervals: the interval between the bottom and middle notes is a minor third, and the interval between the middle and top notes is a major third. By contrast, a major triad has a major third on the bottom and minor third on top. They both contain fifths, because a minor third (three semitones) plus a major third (four semitones) equals a perfect fifth (seven semitones). Chords that are constructed of consecutive (or "stacked") thirds are called ''tertian.'' In Western classical music from 1600 to 182 ...

Second Inversion
The second inversion of a chord is the voicing of a triad, seventh chord, or ninth chord in which the fifth of the chord is the bass note. In this inversion, the bass note and the root of the chord are a fourth apart which traditionally qualifies as a dissonance. There is therefore a tendency for movement and resolution. In notation form, it is referred to with a c following the chord position (For e.g., Ic. Vc or IVc). In figured bass, a second-inversion triad is a chord (as in I), while a second-inversion seventh chord is a chord. Note that any voicing above the bass is allowed. A second inversion chord must have the fifth chord factor in the bass, but it may have any arrangement of the root and third above that, including doubled notes, compound intervals, and omission (G-C-E, G-C-E-G', G-E-G-C'-E', etc.) Examples In the second inversion of a C-major triad, the bass is G — the fifth of the triad — with the root and third stacked above it, forming the intervals ...

Bass Note
In music theory, the bass note of a chord or sonority is the lowest note played or notated. If there are multiple voices it is the note played or notated in the lowest voice (the note furthest in the bass.) Three situations are possible: # The bass note is the root or fundamental of the chord. The chord is in root position. # One of the other pitches of the chord is in the bass. This makes it an inverted chord # The bass note is ''not'' one of the notes in the chord. Such a bass note is an additional note, coloring the chord above it. The name of such a chord is also notated as a slash chord. In pre- tonal theory ( Early music), root notes were not considered and thus the bass was the most defining note of a sonority. See: thoroughbass. In pandiatonic chords the bass often does not determine the chord, as is always the case with a nonharmonic bass A nonchord tone (NCT), nonharmonic tone, or embellishing tone is a note in a piece of music or song that is not part of the ...
