Guitar Chords
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] |
Permutation
In mathematics, a permutation of a set can mean one of two different things: * an arrangement of its members in a sequence or linear order, or * the act or process of changing the linear order of an ordered set. An example of the first meaning is the six permutations (orderings) of the set : written as tuples, they are (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 2, 1). Anagrams of a word whose letters are all different are also permutations: the letters are already ordered in the original word, and the anagram reorders them. The study of permutations of finite sets is an important topic in combinatorics and group theory. Permutations are used in almost every branch of mathematics and in many other fields of science. In computer science, they are used for analyzing sorting algorithms; in quantum physics, for describing states of particles; and in biology, for describing RNA sequences. The number of permutations of distinct objects is factorial, us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Major-thirds Tuning
Among guitar tunings#Alternative, alternative tunings for guitar, a major-thirds tuning is a regular tunings, regular tuning in which each interval (music), interval between successive open string (music), 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 Classical guitar, Spanish guitar's guitar tunings#Standard, 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 regul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regular Tuning
Among guitar tunings#Alternative, alternative guitar tunings, guitar-tunings, regular tunings have equal interval (music), musical intervals between the paired note (music), notes of their successive open string (music), open strings. ''Guitar tuning (music), tunings'' assign pitch (music), pitches to the open string (music), 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 fourth, 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, Minor-thirds, or ''Diminished'' tuning * 4 semitones (major third): Major- ...

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''. ...

Equal Temperament
An equal temperament is a musical temperament or Musical tuning#Tuning systems, tuning system that approximates Just intonation, just intervals by dividing an octave (or other interval) into steps such that the ratio of the frequency, frequencies of any adjacent pair of notes is the same. This system yields Pitch (music), pitch steps perceived as equal in size, due to the logarithmic changes in pitch frequency. In classical music and Western music in general, the most common tuning system since the 18th century has been 12 equal temperament (also known as ''12 tone equal temperament'', ' or ', informally abbreviated as ''12 equal''), which divides the octave into 12 parts, all of which are equal on a logarithmic scale, with a ratio equal to the twelfth root of two, 12th root of 2, (\sqrt[12] ≈ 1.05946). That resulting smallest interval, the width of an octave, is called a semitone or half step. In Western world, Western countries the term ''equal temperamen ...

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, giving rise to the term bottleneck guitar 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 the ...

Steel Guitar
A steel guitar () 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 guitar in a horizontal p ... [...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. A popular variant is vi–IV–V–I, commonly known as the , namesake ...

Twelve-bar Blues
The twelve-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 Rainey. 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 bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
