They are also used on the Who song "Pinball Wizard" and many, many more songs. Dominant sevenths: drop two As previously stated, a dominant seventh is a four-note chord combining a major chord and a minor seventh. For example, the C7 dominant seventh chord adds B to the C-major chord (C,E,G). The naive chord (C,E,G,B) spans six frets from fret 3 to fret 8; such seventh chords "contain some pretty serious stretches in the left hand". An illustration shows a naive C7 chord, which would be extremely difficult to play, besides the open-position C7 chord that is conventional in standard tuning. The standard-tuning implementation of a C7 chord is a second-inversion C7 drop 2 chord, in which the second highest note in a second inversion of the C7 chord is lowered by an octave. Drop-two chords are used for sevenths chords besides the major–minor seventh with dominant function, which are discussed in the section on intermediate chords, below. Drop-two chords are used particularly in jazz guitar. Drop-two second-inversions are examples of openly voiced chords, which are typical of standard tuning and other popular guitar tunings. "Alternatively voiced" seventh chords are commonly played with standard tuning. A list of fret number configurations for some common chords follows: E7:[020100] G7:[320001] A7:[X02020] B7:[X21202] (This B7 requires no barre, unlike the B major.) D7:[XX0212] Other chord inversions Already in basic guitar playing, inversion is important for sevenths chords in standard tuning. It is also important for playing major chords. In standard tuning, chord inversion depends on the bass note's string, and so there are three different forms for the inversion of each major chord, depending on the position of the irregular major thirds interval between the G and B strings. For example, if the note E (the open sixth string) is played over the A minor chord, then the chord would be [0 0 2 2 1 0]. This has the note E as its lowest tone instead of A. It is often written as Am/E, where the letter following the slash indicates the new bass note. However, in popular music it is
