Used by some Brazilian sertanejo musicians on the acoustic guitar to approximate the sound of the viola caipira, a Brazilian country guitar with ten paired strings, traditionally tuned either A-D-F#-A-D or B-E-G#-B-E.
This variant is achieved by lowering the high D string a half step to C♯ when tuned to open D. C♯ is the major seventh of the D major scale, hence the name. It also can be used for both fingerstyle and slide guitar work.
This variant uses an F natural, the minor third.
This tuning has been used by Niko Wenner of Oxbow on the songs "Angel," "Cat and Mouse"; by Ian Thornley of Big Wreck on "Ladylike" and "Overemphasizing" and by Owen Campbell on "Sunshine Road".
DADFAD tuning is ideal for guitarists who are accompanying instruments that are tuned to minor scales, such as the Native American flute.7
This variant is used most notably by Mark Tremonti of Alter Bridge and Creed. Eight of the songs in which it is used are "Are You Ready?",8 "Faceless Man",9 "My Sacrifice",10 "Weathered",11 "Open Your Eyes",12 "Ghost of Days Gone By" (half-step down),13 "Life Must Go On",14 and “Fortress” (half-step down).15 It is also used on "Rain",16 "Brains", and "New Way Out", all tuned down 1 and a half steps (BF♯BF♯BB). Mark has mentioned in his instructional DVD that this tuning is one of his favorites because of its simplicity. It is also used by the Goo Goo Dolls in their song "Black Balloon", which was tuned down a half step on the album but played live in Open D5. "Without You", "Emotion Sickness" and "Paint Pastel Princess" by Australian band Silverchair also uses the Open D5 tuning, but down half a step. Fair to Midland use this tuning tuned down 1 full step (CGCGCC) and 1 1/2 steps (BF♯BF♯BB).
A variation on the above Open D5 tuning, is occasionally used by folk guitarists, such as Stephen Stills on the song "4+20".17 It has the advantage of a ringing pair of identical Ds on the third and fourth strings, which can be used to carry a melody line above a bed of D5 created by the other strings.
This tuning has been used by:
Nicknamed the "Wind of Change," this tuning was used by Peter Frampton on his song of the same name. Frampton discovered this tuning while browsing guitars at the home of George Harrison, who had a large collection of guitars in various tunings. When speaking of the tuning in an interview, Frampton said, "The low E and A strings drop down to D, the fourth string remains unchanged, the third string goes up to A, the second string up to D, and the first string up to F♯ , so there's a D triad on top and three Ds on the bottom. It's a very strange tuning, but oh my God, it sounds huge."
