On a double-neck instrument, the neck nearest the player will normally be some form of C6, and the furthest neck E9. Necks with 12 or more strings can be used with universal'' tunings which combine the features of C6 and E9. On a 12-string pedal steel guitar, all 12 strings are tuned and played individually, not as six double courses as on the 12-string guitar. On a lap steel guitar there may be up to four necks, each tuned differently. The C6 tuning was a common tuning for a six-string lap steel in the 1920s and 1930s. Tunings with a sixth interval are popular in Western swing and jazz, while tunings containing sevenths are often chosen for blues and rock music.
