\\clef "treble_8" \\time 3/4 4 } Among alternative tunings for the guitar, an open G tuning is an open tuning that features the G-major chord; its open notes are selected from the notes of a G-major chord, such as the G-major triad (G,B,D). For example, a popular open-G tuning is D-G-D-G-B-D (low to high). An open-G tuning allows a G-major chord to be strummed on all six strings with neither fretting of the left hand nor a capo. Like other open tunings, it allows the eleven major chords besides G major each to be strummed by barring at most one finger on exactly one fret.[1] Open tunings are common in blues and folk music,[2] and they are used in the playing of slide and bottleneck guitars.[1][3] {{anchor|Russian}}Repetitive variants for special instrumentsRepetitive open-G tunings are used by Russian guitars, Dobro guitars, and banjos. They repeat three open-string notes. The repetitive open-G tuning D-G-B-D-G-B-D \\clef "treble_8" \\time 3/4 4 } is used by the Russian guitar, which has seven strings tuned mostly in triads, in contrast to other guitars, which are tuned mostly in fourths.[4][5][6] Dobros use a full six-string tuning with a bottom G: G-B-D-G-B-D, low to high. The two lowest strings are, accordingly, tuned three semitones higher for the lowest string (from E up to G) and two semitones higher for the second-lowest string (from A up to B) while the highest string is tuned two semitones lower (from E down to D), relative to standard tuning. Five-string banjo's standard tuning is also an Open G: g-D-G-B-D, where the lower case "g" denotes the highest-pitched "drone string", physically located next to (above) the lowest-pitched string, the first upper case "D".[7] Overtones of the fundamental note G{{main|Overtones tuning}}Bad Company guitarist Mick Ralphs has used another open-G tuning, which listed the initial six overtones of the G note, G-G-D-G-B-D \\clef "treble_8" \\time 3/4 4 } for "Hey Hey" and while writing the demo of "Can't Get Enough".[8]The overtones tuning G-G-D-G-B-D was used by Joni Mitchell for "Electricity", "For the Roses", and "Hunter (The Good Samaritan)".[9] Truncating this tuning to G-D-G-B-D for his five-string guitar, Keith Richards plays this overtones-tuning on The Rolling Stones' "Honky Tonk Women", "Brown Sugar" and "Start Me Up".[10] American rock band Eagles of Death Metal, uses this tuning for the majority of their songs.
