note rather than the high G note for "Can't Get Enough" on Bad Company. Ralphs said, "It needs the open C to have that ring," and "it never really sounds right in standard tuning". Open G Mick Ralphs' open-C tuning was originally an open-G tuning, which listed the initial six overtones of the G note, namely G–G–D–G–B–D; Ralphs used this open-G tuning for "Hey Hey" and while writing the demo of "Can't Get Enough". Open-G tuning usually refers to D–G–D–G–B–D. The open G tuning variant G–G–D–G–B–D was used by Joni Mitchell for "Electricity", "For the Roses" and "Hunter (The Good Samaritan)". Truncating this tuning to G–D–G–B–D for his five-string guitar, Keith Richards uses this overtones-tuning on The Rolling Stones's "Honky Tonk Women", "Brown Sugar" and "Start Me Up". The seven-string Russian guitar uses the open-G tuning D–G–B–D–G–B–D, which contains mostly major and minor thirds. Creating any kind of open tuning Any kind of chordal tuning can be achieved, simply by using the notes in the chord and tuning the strings to those notes. For example, Asus4 has the notes A, D, E. By tuning the strings to only those notes, it creates a chordal Asus4 tuning. {| class="wikitable" |+Power chord (fifths) open tunings: |- |A5 || E–A–E–A–A–E |- |B5 || F–B–F–B–B–F |- |C5 || C–G–C–G–G–G |- |D5 || D–A–D–A–D–D |- |E5 || E–B–E–E–B–E |- |F5 || F–C–C–C–C–F |- |G5 || D–G–D–G–D–G |} Bass players may omit the last two strings. Minor or "cross-note" tunings Cross-note tunings include a minor third, so giving a minor chord with open strings. Fretting the minor-third string at the first fret produces a major-third, so allowing a one-finger fretting of a major chord. By contrast, it is more difficult to fret a minor chord using an open major-chord tuning. Bukka White and Skip James are well-known for using cross-note E-minor in their music. Other open chordal tunings Some guitarists choose open tunings that use more complex chords, which gives them more available intervals on the open strings. C6, E6, E7, E6/9 and other such tunings are common among lap-steel players such as Hawaiian slack-key guitarists and country guitarists, and are also sometimes applied to the regular guitar by bottleneck (a slide repurposed from a glass bottle) players striving to emulate these styles. A common C6 tuning, for example, is C–E–G–A–C–E, which provides open major and minor thirds, open major and minor sixths, fifths, and octaves.
