What device enables a player to use the same chord shapes on a guitar to be played a number of frets higher to raise the key uniformly?
Barre chord than an open, unfretted, string. Barre chords are a distinctive part of the sound of pop music and rock music. Using the barre technique, the guitarist can fret a familiar chord that is usually played with open strings, and then transpose, or raise, the chord a number of half-steps higher, similar to the use of a capo. For example, if a guitarist plays an E major and wants the next chord to be an F major, barring the open E major up two frets (thus two semitones) from the open position produces a barred F major chord.

Guitar chord three frets are needed for the guitar chords—major, minor, and dominant sevenths—which are emphasized in introductions to guitar-playing and to the fundamentals of music. Each major and minor chord can be played on exactly two successive frets on exactly three successive strings, and therefore each needs only two fingers. Other chords—seconds, fourths, sevenths, and ninths—are played on only three successive frets. The circle of fifths was discussed in the section on intermediate guitar-chords. Other progressions are also based on sequences of third intervals; progressions are occasionally based on sequences of second intervals. As their categorical name suggests, "extended chords" indeed
