if they are not familiar with the fingering for seventh chords. The use of slash chords can enable beginning musicians to perform quite complex chords. For example, even though a beginner may not know what a dominant seventh flat ninth chord is, they will be able to play this chord if it is notated in slash notation, as long as they are familiar with the diminished seventh chord. In the key of C, a G79 chord could be notated in slash notation as B°7/G (or B°7/G bass). In jazz Some sources notate slash chords with a horizontal line, although this is discouraged as this type of notation can also imply a polychord. While almost all pop and rock usages of slash chords are intended to be read as a chord with a bass note underneath it other than the root of the chord, in jazz and jazz fusion, sometimes a chord notated as F/A is intended to be read as a polychord; in this example, the polychord would be an F major chord (the notes F, A, and C) and an A major chord (the notes A, C, and E) played simultaneously. To avoid ambiguity in a jazz or fusion chart, some arrangers use the notation "bass" to indicate when the second note (after the slash) is a bass note. Thus, F/A bass indicates an F major chord with an A bass note, whereas F/A may indicate a polychord with an F major chord and an A major chord.
