Why do Some Guitar Chords Have a Slash?

Slash chords in guitar music can be both a source of curiosity and elegance, providing musicians with a way to communicate specific bass notes and voicings. Understanding slash chords can enhance your interpretive skills and open up new possibilities in chord playing. Let's delve into the world of slash chords and explore why they exist and what they signify.

Understanding Slash Chords: What They Are and How to Use Them

Slash chords are not a mystery. They are an intuitive notation that provides information about the bass note in a chord. As seen in songs like the Oasis hit 'Don’t Look Back in Anger', where the pre-chorus utilizes slash chords, this notation can significantly alter the sound and feel of the music.

The use of slash chords is a practice that has evolved over the years, primarily in contemporary contexts such as lead sheets and song arrangements. Standard music notation typically omits the bass part, but slash chords solve this issue by indicating the bass note. For instance, a C/D slash chord means that the root note of the chord is C, but the bass note is D. This is a clear and concise way to communicate to the musician which note should be emphasized.

How to Play Slash Chords:

To play a C/D chord, you would typically play a C chord shape on your guitar with the D note as the lowest bass note. If you were to play a basic C chord with your standard guitar tuning, you could let the unfretted low E string (which corresponds to D) ring out. This provides a clear D bass note, satisfying the requirements of the slash chord.

Let's explore a few more examples of how slash chords work:

Cm/Eb (C minor 1st inversion) D/A (D major 2nd inversion) A7/G (A dominant 7th with a G bass note) Gadd9/A (G major 9th with a G bass note) Dm/F (D minor with an F bass note)

The Historical Context of Slash Chords

The term 'slash chord' is relatively modern and originated in the contemporary world of lead sheets and song arrangements. The term didn't exist in standardized music notation, where the focus lies on the voicing of the chord from the composer's standpoint.

However, in contemporary music, the composer often allows a degree of flexibility in the voicings, leaving it up to the guitarist or other instrumentalists to choose a suitable chord shape. This interpretative liberty has led to the invention or reinvention of the slash chord. The slash indicates that the bass note is different from what you would expect, based on the root note of the chord.

Conclusion

Mastering slash chords can significantly enhance your understanding and execution of music. Not only do they provide a clear indication of the bass note, but they also offer flexibility in choosing the right voicing. Whether you're a musician or a guitar player, understanding slash chords can unlock new avenues in your music expression.
