Seventh (chord)
In music, the seventh factor of a chord is the note or pitch seven scale degrees above the root or tonal center. When the seventh is the bass note, or lowest note, of the expressed chord, the chord is in third inversion . Conventionally, the seventh is fourth in importance to the root, fifth, and third, with third inversion being the third strongest inversion and the seventh variably minor or major. In jazz In jazz chords and theory, and classical music theory, the seventh is what defines a chord as a " seventh chord". Moreover, most triads that appear in lead sheets or fake books can have sevenths added to them, using the performer's discretion and "ear". For example, if a tune is in the key of C, if there is a G chord, the chord-playing performer will usually "voice" this chord as G7. While in a strict classical music context, the notes of a G7 chord would be "G–B–D–F", in jazz, the fifth of the chord is often omitted. The root is also often omitted if playin ...

Seventh Chord
A seventh chord is a chord consisting of a triad plus a note forming an interval of a seventh above the chord's root. When not otherwise specified, a "seventh chord" usually means a dominant seventh chord: a major triad together with a minor seventh. However, a variety of sevenths may be added to a variety of triads, resulting in many different types of seventh chords. In its earliest usage, the seventh was introduced solely as an embellishing or nonchord tone. The seventh destabilized the triad, and allowed the composer to emphasize movement in a given direction. As time passed and the collective ear of the western world became more accustomed to dissonance, the seventh was allowed to become a part of the chord itself, and in some modern music, jazz in particular, nearly every chord is a seventh chord. Additionally, the general acceptance of equal temperament during the 19th century reduced the dissonance of some earlier forms of sevenths. Classification Most tex ...

Altered Dominant
An altered chord is a chord that replaces one or more notes from the diatonic scale with a neighboring pitch from the chromatic scale. By the broadest definition, any chord with a non-diatonic chord tone is an altered chord. The simplest example of altered chords is the use of borrowed chords, chords borrowed from the parallel key, and the most common is the use of secondary dominants. As Alfred Blatter explains, "An altered chord occurs when one of the standard, functional chords is given another quality by the modification of one or more components of the chord." For example, altered notes may be used as leading tones to emphasize their diatonic neighbors. Contrast this with chord extensions: In jazz harmony, chromatic alteration is either the addition of notes not in the scale or expansion of a hordprogression by adding extra non-diatonic chords.Arkin, Eddie (2004). ''Creative Chord Substitution for Jazz Guitar'', p. 42. . For example, "A C major scale with an added D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Added Tone Chord
An added tone chord, or added note chord, is a non- tertian chord composed of a triad and an extra "added" note. Any tone that is not a seventh factor is commonly categorized as an added tone. It can be outside the tertian sequence of ascending thirds from the root, such as the added sixth or fourth, or it can be in a chord that doesn't consist of a continuous stack of thirds, such as the added thirteenth (six thirds from the root, but the chord doesn't have the previous tertian notes – the seventh, ninth or eleventh). The concept of added tones is convenient in that all notes may be related to familiar chords.Jones, George (1994). ''HarperCollins College Outline Music Theory'', p.50. . Inversions of added tone chords where the added tone is the bass note are usually simply notated as slash chords instead of added-tone chords. For example, instead of Cadd2/D, just C/D is used. An added tone such as fourth voiced below the root may suggest polytonality. The practice of add ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jazz Piano
Jazz piano is a collective term for the techniques pianists use when playing jazz. The piano has been an integral part of the jazz idiom since its inception, in both solo and ensemble settings. Its role is multifaceted due largely to the instrument's combined melodic and harmonic capabilities. For this reason it is an important tool of jazz musicians and composers for teaching and learning jazz theory and set arrangement, regardless of their main instrument. By extension the phrase 'jazz piano' can refer to similar techniques on any keyboard instrument. Along with the guitar, vibraphone, and other keyboard instruments, the piano is one of the instruments in a jazz combo that can play both single notes and chords rather than only single notes as does the saxophone or trumpet. Beginning A new style known as “stride” or “Harlem stride” emerged during the 1920s, predominantly in New York. James P. Johnson was a prominent adherent.

Jazz Guitar
Jazz guitar may refer to either a type of electric guitar or a guitar playing style in jazz, using electric amplification to increase the volume of acoustic guitars. In the early 1930s, jazz musicians sought to amplify their sound to be heard over loud big bands. When guitarists in big bands switched from acoustic to semi-acoustic guitar and began using amplifiers, it enabled them to play solos. Jazz guitar had an important influence on jazz in the beginning of the twentieth century. Although the earliest guitars used in jazz were acoustic and acoustic guitars are still sometimes used in jazz, most jazz guitarists since the 1940s have performed on an electrically amplified guitar or electric guitar. Traditionally, jazz electric guitarists use an archtop with a relatively broad hollow sound-box, violin-style f-holes, a " floating bridge", and a magnetic pickup. Solid body guitars, mass-produced since the early 1950s, are also used. Jazz guitar playing styles include '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extended Chord
In music, extended chords are certain chords (built from thirds) or triads with notes ''extended'', or added, beyond the seventh. Ninth, eleventh, and thirteenth chords are extended chords. The thirteenth is the farthest extension diatonically possible as, by that point, all seven tonal degrees are represented within the chord (the next extension, the fifteenth, is the same as the root of the chord). In practice however, extended chords do not typically use all the chord members; when it is not altered, the fifth is often omitted, as are notes between the seventh and the highest note (i.e., the ninth is often omitted in an eleventh chord; the ninth and eleventh are usually omitted in a thirteenth chord), unless they are altered to give a special texture. Chords extended beyond the seventh are rarely seen in the Baroque era, and are used more frequently in the Classical era. The Romantic era saw greatly increased use of extended harmony. Extended harmony prior to the 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Major And Minor
In Western music, the adjectives major and minor may describe a chord, scale, or key. As such, composition, movement, section, or phrase may be referred to by its key, including whether that key is major or minor. Intervals Some intervals may be referred to as ''major'' and ''minor''. A major interval is one semitone larger than a minor interval. The words ''perfect'', ''diminished'', and ''augmented'' are also used to describe the quality of an interval. Only the intervals of a second, third, sixth, and seventh (and the compound intervals based on them) may be major or minor (or, rarely, diminished or augmented). Unisons, fourths, fifths, and octaves and their compound interval must be perfect (or, rarely, diminished or augmented). In Western music, a minor chord "sounds darker than a major chord".

Jazz Improvisation
Jazz improvisation is the spontaneous invention of melodic solo lines or accompaniment parts in a performance of jazz music. It is one of the defining elements of jazz. Improvisation is composing on the spot, when a singer or instrumentalist invents melodies and lines over a chord progression played by rhythm section instruments (piano, guitar, double bass) and accompanied by drums. Although blues, rock, and other genres use improvisation, it is done over relatively simple chord progressions which often remain in one key (or closely related keys using the circle of fifths, such as a song in C Major modulating to G Major). Jazz improvisation is distinguished from this approach by chordal complexity, often with one or more chord changes per bar, altered chords, extended chords, tritone substitution, unusual chords (e.g., augmented chords), and extensive use of ii–V–I progression, all of which typically move through multiple keys within a single song.

Classical Music
Classical music generally refers to the art music of the Western world, considered to be distinct from Western folk music or popular music traditions. It is sometimes distinguished as Western classical music, as the term "classical music" also applies to non-Western art music. Classical music is often characterized by formality and complexity in its musical form and harmonic organization, particularly with the use of polyphony. Since at least the ninth century it has been primarily a written tradition, spawning a sophisticated notational system, as well as accompanying literature in analytical, critical, historiographical, musicological and philosophical practices. A foundational component of Western Culture, classical music is frequently seen from the perspective of individual or groups of composers, whose compositions, personalities and beliefs have fundamentally shaped its history. Rooted in the patronage of churches and royal courts in Western Europe, survivi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chord Voicing
In music theory, voicing refers to two closely related concepts: # How a musician or group distributes, or spaces, notes and chords on one or more instruments # The simultaneous vertical placement of notes in relation to each other; this relates to the concepts of spacing and doubling It includes the instrumentation and vertical spacing and ordering of the musical notes in a chord: which notes are on the top or in the middle, which ones are doubled, which octave each is in, and which instruments or voices perform each note. Vertical placement The following three chords are all C-major triads in root position with different voicings. The first is in close position (the most compact voicing), while the second and third are in open position (that is, with wider spacing). Notice also that the G is doubled at the octave in the third chord; that is, it appears in two different octaves. : Examples Many composers, as they developed and gained experience, became more enterp ...
