Understanding Suspended Chords: A Unique Sound in Music

Suspended chords have a unique sound that sets them apart from other chord types. To understand if a suspended chord more closely resembles a major 7th or diminished 7th chord, we must first explore the nature of these chords and their dissonant qualities.

The Nature of Suspension in Chords

A suspended chord, often denoted as Sus4 or Sus2, has a distinctive sound that can be confusing when compared to more familiar chords. Unlike a major or minor 7th chord, a suspended chord is characterized by a dissonance, or a note that does not naturally belong to the chord. This dissonant note creates an inherent tension within the chord, making it feel unresolved and in need of resolution.

When considering the question of whether a suspended chord sounds more like a major 7th or diminished 7th chord, it's important to recognize that the dissonance in a suspended chord is a critical component. A suspension is a note that does not belong to the current chord but rather comes from the previous chord. This note introduces a moment of tension and creates a sense of anticipation for the resolution to a more consonant chord.

Comparing Suspended Chords to Other Chords

To provide a more concrete comparison, let's look at the interval content of the chords in question:

Total Interval Content: Suspended Chord (2/1 or 4/3): 255 semitones (considering both 2/1 and 4/3 suspensions share the same interval content) Major 7th Chord (Major): 345 semitones Minor 7th Chord (Minor): 345 semitones Dominant 7th Chord (Dominant 7th): 233456 semitones Diminished 7th Chord (Diminished 7th): 333366 semitones

From this table, it's clear that none of the other chords closely resemble the suspended chords in terms of overall interval content. The dominant 7th chord has the same interval pattern as the suspended chord plus additional intervals, but the overall sound and feel are not similar due to the nature of the dissonance.

Expectations in Musical Context

The second way to approach this question is through the lens of musical expectations. In a tonal context, the expectation is that a suspension will resolve to a major or minor chord. The anticipation of this resolution can make the suspended chord feel more like the chord that follows it. If a suspended chord is followed by a major chord, it might feel more like a major 7th chord due to the resolution. If it's followed by a minor chord, it might feel more like a minor 7th chord but with that initial tension.

Therefore, the answer to whether a suspended chord sounds more like a major 7th or diminished 7th chord is not straightforward. It depends on the context and the resolution of the dissonance. Suspended chords are unique and should be appreciated in their own right, rather than being compared directly to other chord types.
