Guitar Chord
In music, a guitar chord is a set of notes played on a guitar. A chord's notes are often played simultaneously, but they can be played sequentially in an arpeggio. The implementation of guitar chords depends on the guitar tuning. Most guitars used in popular music have six strings with the "standard" tuning of the Spanish classical guitar, namely E–A–D–G–B–E' (from the lowest pitched string to the highest); in standard tuning, the intervals present among adjacent strings are perfect fourths except for the major third (G,B). Standard tuning requires four chord-shapes for the major triads. There are separate chord-forms for chords having their root note on the third, fourth, fifth, and sixth strings. For a six-string guitar in standard tuning, it may be necessary to drop or omit one or more tones from the chord; this is typically the root or fifth. The layout of notes on the fretboard in standard tuning often forces guitarists to permute the tonal order of notes in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Music
Music is generally defined as the art of arranging sound to create some combination of form, harmony, melody, rhythm or otherwise expressive content. Exact definitions of music vary considerably around the world, though it is an aspect of all human societies, a cultural universal. While scholars agree that music is defined by a few specific elements, there is no consensus on their precise definitions. The creation of music is commonly divided into musical composition, musical improvisation, and musical performance, though the topic itself extends into academic disciplines, criticism, philosophy, and psychology. Music may be performed or improvised using a vast range of instruments, including the human voice. In some musical contexts, a performance or composition may be to some extent improvised. For instance, in Hindustani classical music, the performer plays spontaneously while following a partially defined structure and using characteristic motifs. In modal ...

All-fourths Tuning
Among alternative tunings for the guitar, all-fourths tuning is a regular tuning.: In contrast, the standard tuning has one irregularity—a major third between the third and second strings—while having perfect fourths between the other successive strings. The standard tuning's irregular major-third is replaced by a perfect fourth in all-fourths tuning, which has the open notes E2-A2-D3-G3-C4-F4. Among regular tunings, this all-fourths tuning best approximates the standard tuning. In all guitar tunings, the higher-octave version of a chord can be found by translating a chord by twelve frets higher along the fretboard. In every regular tuning, for example in all-fourths tuning, chords and intervals can be moved also ''diagonally''. For all-fourths tuning, all twelve major chords (in the first or open positions) are generated by two chords, the open F major chord and the D major chord. The regularity of chord-patterns reduces the number of finger&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Major-thirds Tuning
Among alternative tunings for guitar, a major-thirds tuning is a regular tuning in which each interval between successive open strings is a major third ("M3" in musical abbreviation). Other names for major-thirds tuning include major-third tuning, M3 tuning, all-thirds tuning, and augmented tuning. By definition, a major-third interval separates two notes that differ by exactly four semitones (one-third of the twelve-note octave). The Spanish guitar's tuning mixes four perfect fourths (five semitones) and one major-third, the latter occurring between the G and B strings: :E–A–D–''G''–''B''–E. This tuning, which is used for acoustic and electric guitars, is called "''standard''" in English, a convention that is followed in this article. While standard tuning is irregular, mixing four fourths and one major third, M3 tunings are regular: Only major-third intervals occur between the successive strings of the M3 tunings, for example, the open augmen ...

Regular Tuning
Among alternative guitar-tunings, regular tunings have equal musical intervals between the paired notes of their successive open strings. ''Guitar tunings'' assign pitches to the open strings of guitars. Tunings can be described by the particular pitches that are denoted by notes in Western music. By convention, the notes are ordered from lowest to highest. The ''standard tuning'' defines the string pitches as E, A, D, G, B, and E. Between the open-strings of the standard tuning are three perfect-fourths (E–A, A–D, D–G), then the major third G–B, and the fourth perfect-fourth B–E. In contrast, regular tunings have constant intervals between their successive open-strings: * 3 semitones (minor third): Minor-thirds, or ''Diminished'' tuning * 4 semitones (major third): Major-thirds or ''Augmented'' tuning, * 5 semitones (perfect fourth): All-fourths tuning, * 6 semitones (augmented fourth, tritone, or diminished fifth): Augmented-fourths tu ...

Consonance And Dissonance
In music, consonance and dissonance are categorizations of simultaneous or successive sounds. Within the Western tradition, some listeners associate consonance with sweetness, pleasantness, and acceptability, and dissonance with harshness, unpleasantness, or unacceptability, although there is broad acknowledgement that this depends also on familiarity and musical expertise. The terms form a structural dichotomy in which they define each other by mutual exclusion: a consonance is what is not dissonant, and a dissonance is what is not consonant. However, a finer consideration shows that the distinction forms a gradation, from the most consonant to the most dissonant. In casual discourse, as German composer and music theorist Paul Hindemith stressed, "The two concepts have never been completely explained, and for a thousand years the definitions have varied". The term ''sonance'' has been proposed to encompass or refer indistinctly to the terms ''consonance'' and ''dissonance''. De ...

Equal Temperament
An equal temperament is a musical temperament or tuning system, which approximates just intervals by dividing an octave (or other interval) into equal steps. This means the ratio of the frequencies of any adjacent pair of notes is the same, which gives an equal perceived step size as pitch is perceived roughly as the logarithm of frequency. In classical music and Western music in general, the most common tuning system since the 18th century has been twelve-tone equal temperament (also known as 12 equal temperament, 12-TET or 12-ET; informally abbreviated to twelve equal), which divides the octave into 12 parts, all of which are equal on a logarithmic scale, with a ratio equal to the 12th root of 2 ( ≈ 1.05946). That resulting smallest interval, the width of an octave, is called a semitone or half step. In Western countries the term ''equal temperament'', without qualification, generally means 12-TET. In modern times, 12-TET is usually tuned relative to a standard pit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slide Guitar
Slide guitar is a technique for playing the guitar that is often used in blues music. It involves playing a guitar while holding a hard object (a slide) against the strings, creating the opportunity for glissando effects and deep vibratos that reflect characteristics of the human singing voice. It typically involves playing the guitar in the traditional position (flat against the body) with the use of a slide fitted on one of the guitarist's fingers. The slide may be a metal or glass tube, such as the neck of a bottle. The term bottleneck was historically used to describe this type of playing. The strings are typically plucked (not strummed) while the slide is moved over the strings to change the pitch. The guitar may also be placed on the player's lap and played with a hand-held bar ( lap steel guitar). Creating music with a slide of some type has been traced back to African stringed instruments and also to the origin of the steel guitar in Hawaii. Near the beginning of ...

Steel Guitar
A steel guitar ( haw, kīkākila) is any guitar played while moving a steel bar or similar hard object against plucked strings. The bar itself is called a "steel" and is the source of the name "steel guitar". The instrument differs from a conventional guitar in that it is played without using frets; conceptually, it is somewhat akin to playing a guitar with one finger (the bar). Known for its portamento capabilities, gliding smoothly over every pitch between notes, the instrument can produce a sinuous crying sound and deep vibrato emulating the human singing voice. Typically, the strings are plucked (not strummed) by the fingers of the dominant hand, while the steel tone bar is pressed lightly against the strings and moved by the opposite hand. The idea of creating music with a slide of some type has been traced back to early African instruments, but the modern steel guitar was conceived and popularized in the Hawaiian Islands. The Hawaiians began playing a conventional guit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I–IV–V–I
In music, I–IV–V–I or IV–V–I is a chord progression and cadence that, "unequivocally defines the point of origin and the total system, the key (music), key."Oswald Jonas, Jonas, Oswald (1982). ''Introduction to the Theory of Heinrich Schenker'' (1934: ''Das Wesen des musikalischen Kunstwerks: Eine Einführung in Die Lehre Heinrich Schenkers''), p. 23. Trans. John Rothgeb. . Composers often begin pieces with this progression as an exposition of the tonality: According to theorist Oswald Jonas, "[a]long with motion toward the fifth (V), IV [the subdominant] appears as a corrective, depriving V (the dominant (music), dominant) of its independence and pointing it back in the direction of its origin [I]." In the key (music), key of C, IV provides the note F and eliminates the possibility of G major, which requires F. The progression is also often used at the conclusion (music), end of works and sections. See also *Predominant chord *Three-chord song *V–IV–I turnaround *i ...

Twelve-bar Blues
The 12-bar blues (or blues changes) is one of the most prominent chord progressions in popular music. The blues progression has a distinctive form in lyrics, phrase, chord structure, and duration. In its basic form, it is predominantly based on the I, IV, and V chords of a key. Mastery of the blues and rhythm changes are "critical elements for building a jazz repertoire". Background The blues originated from a combination of work songs, spirituals, and early southern country music. The music was passed down through oral tradition. It was first written down by W. C. Handy, an African American composer and band leader. Its popularity led to the creation of "race records" and the popularity of blues singers like Bessie Smith and Ma Rainy. The style of music heard on race records was later called "rhythm and blues" (R & B). As the music became more popular, more people wanted to perform it. General patterns that existed in the blues were formalized, one of these being the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Guitar
The Russian guitar (sometimes referred to as a "Gypsy guitar") is an acoustic seven-string guitar that was developed in Russia toward the end of the 18th century: it shares most of its organological features with the Spanish guitar, although some historians insist on English guitar descent. It is known in Russian as the (), or affectionately as the (), which translates to "seven-stringer". These guitars are most commonly tuned to an open G chord as follows: . In classical literature, the lowest string (D) occasionally is tuned down to the C. History Although in a number of sources the invention of the Russian guitar is attributed to Andrei Sychra (1773–1850), there are strong reasons to believe that the instrument was already in use when Sychra began his career. It is true that Sychra was very influential in creating the school of Russian guitar playing. He left over a thousand compositions, seventy-five of which were republished in the 1840s by Stellovsky, and then again ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
