In music, a barre chord (also known as bar chord or rarely barr chord) is a type of guitar chord, where one or more fingers are used to press down multiple strings across the guitar fingerboard (like a bar pressing down the strings), enabling the guitarist to play a chord not restricted by the tones of the guitar's open strings. Barre chords are often referred to as "moveable" chords, as the whole hand may easily be moved up and down the neck, "in one movement". Commonly used in most popular and classical music, they are frequently used in combination with "open" or standard guitar chords.
Though slightly affecting tone quality, fretting a chord transposes, or raises, the chord a number of half-steps higher, similar to the use of a capo.
Among fingerstyle guitar techniques, a particular robust tradition exists for classical guitar.
Classical guitar technique can be organized broadly into subsections for the right hand, the left hand, and miscellaneous. In guitar performance elements such as musical dynamic and tonal variation are mostly determined by the hand that physically produces the sound. In other words, the hand that plucks the strings defines the musical expression. Historically, this role has been assigned to the dominant hand which, for the majority of players, is the right hand. Similar reasoning is behind string players using the right hand for controlling the bow. In the following discussion the role of the hands should be reversed when considering left-handed players.
In music, a guitar chord is a set of notes that is 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 a chord.
Celtic music is a broad grouping of musical genres that evolved out of the folk musical traditions of the Celtic people of Western Europe. It refers to both orally-transmitted traditional music and recorded music and the styles vary considerably to include everything from "trad" (traditional) music to a wide range of hybrids.
Celtic music means two things mainly. First, it is the music of the peoples identifying themselves as Celts. Secondly, it refers to whatever qualities may be unique to the musics of the Celtic Nations. Many notable Celtic musicians such as Alan Stivell and Paddy Moloney claim that the different Celtic musics have much in common. These common melodic practices may be used widely across Celtic Music:
