A sus7 chord often precedes a dominant chord built from the same Root. In lieu of a regular ii7-V7 we may find Vsus7-V7. In the key of C, instead of Dm7 - G7 we would get: Gsus7 - G7.
How To Play The 7sus4 Chord. This is a very easy chord to play if you are used to playing barre chords. Imagine that you are playing a standard seventh shape, but instead of using your second (index) finger to play the major third, use your fourth (little) finger to play the fourth.
For example, Gsus2 (G–A–D) is the first inversion of Dsus4 (D–G–A) which is the second inversion of Gsus2 (G–A–D). The sus2 and sus4 chords both have inversions that create quartal and quintal chords (A–D–G, G–D–A) with two stacked perfect fourths or perfect fifths.
A chord is called suspended (sus for short) when it has no interval of a third in it. This is important because the third tells us if a chord is major or minor. Instead, a suspended chord uses either a perfect fourth (P4) or a major second (M2) in place of the major or minor third (M3 or m3).
The forbidden chord, or tritone, can be identified as a particularly dissonant interval in a piece of music. It is typically characterized by a tension-filled, unstable sound.
The two basic sus chords are the sus4 and sus2 chords. In the sus4 chord (also labeled simply as “sus”), a perfect 4th replaces the 3rd of the chord. In the sus2 chord (sometimes called “sus9”), a major 2nd replaces the 3rd of the chord. Both of these sus chords have a perfect 5th from the root to the fifth.
A sus chord is a “two chord” over the root of its corresponding “five chord”. That is to say, D7/G = G7sus. Any voicing for a minor seventh chord is a voicing for a sus chord a perfect fifth lower. In fact, whether a band plays a D7 or a G7sus is entirely up to one musician: the bass player.
TWO MAIN TYPES OF SUSPENDED CHORDS
D (root) – E (2nd scale degree, our suspended note) – A (perfect 5th). Similarly, a Dsus4 chord is composed of the following three notes: D (root) – G (4th scale degree, our suspended note) – A (5th scale degree).
Four of the scale degrees in the major scale build suspended chords that have a minor 7th interval, also called 7sus4 chords. Those scales degrees are the 2nd, 3rd, 5th, and 6th, and for C major, those notes are D, E, G, and A.
The 7sus4 chord is a dominant seventh chord with a suspended fourth. In the C dominant seventh chord: … raising E (the third tone): …by a half step (to F):
Sus7 is typically a shortcut for sus4 7, so a sus4 triad with a minor seventh: CFGBb. Sus4 maj7 is possible, but far less common. It would mostly be used in modern modal music (Jazz, Fusion, concert music)
We will start with a common suspended chord format: the V7sus4 chord. This type of chord, known as dominant with a suspended fourth, usually appears replacing the second degree.
The six-string F chord is one of the hardest standard chord shape to play on the guitar. When many people try to play the F chord on guitar (and often succeed), it's with far too much struggle and effort than is actually necessary. Even extremely influential guitarists can have a hard time with barre chords.
C chord (barred)
However, the barred C chord is one of the hardest guitar chords for beginners. Although it involves the same notes but is rearranged (in a different order), this chord is more challenging to play. That is because we also need a bar in order to play it.
The diminished chord is the darkest chord in music. This is because it's constructed with stacked minor third intervals.
Most instruments (e.g., saxophone, trumpet, trombone, human voice) can only play one note at a time and, therefore, can't play chords; these are referred to as single-note instruments.
Be that as it may, a progression in a minor key or heavy on minor chords tends to sound the most melancholy to listeners. A similar effect can be achieved with diminished chords, 7ths, and other extended voicings.
The famous four chords used in many pop song progressions are the I, V, vi and IV chords of a major key. The roman numerals represent the numbers of the major scale we begin a chord from (1, 5, 6, 4) so in C major this would be C, G, Amin, F or in G major it would be G, D, Emin, C.
