How to play Dsus4 on guitar
The first shape above reads x x 0 2 3 3 from the low E string to the high E string (x means you do not play that string, 0 is an open string). The lowest note you play is D. The other diagrams show the same chord higher up the neck: pick the one closest to the chords before and after it in your song.
Let the open strings ring: strum slowly once and check that every note sounds clean before you speed up.
Which keys use Dsus4?
Dsus4 is not built from the notes of a single major key, so it usually appears as a colour chord: a borrowed chord, a passing chord or a suspension that resolves to the next chord.
Scales to play over Dsus4
To improvise over Dsus4, start with D major scale. All of these scales contain every note of the chord: D major scale, D natural minor scale, D harmonic minor scale, D melodic minor scale, D minor pentatonic scale, D blues scale, D Dorian mode, D Phrygian mode and D Mixolydian mode. Aim for the chord notes on strong beats and use the other notes to move between them.
About sus4 chords
The third is replaced by a perfect fourth: 1 4 5. The fourth leans on the third it replaces, so the chord sounds expectant, as if holding its breath before resolving. It is the most common sus chord, and 'sus' alone usually means sus4. For example Asus4: A D E.
The classic gesture is sus4 to major on the same root, especially on V before the cadence: Vsus4 V I. Rock riffs alternate sus4 and major in one bar, folk players decorate open chords with it, and gospel and soul use a 9sus4 voicing, often written IV/V (for example F/G), as a softer dominant.
Open Dsus4 (xx0233), Asus4 (x02230) and Esus4 (022200) are one finger away from their major chords. Movable: in the E-shape barre, raise the third on the 3rd string by one fret; in the A-shape barre, raise the third on the 2nd string by one fret. Alternate sus4 and major with that single finger to build riffs.
Do not add the third to a sus4 chord: it cancels the suspension and creates a harsh clash. A sus4 usually resolves to the major chord, though resolving to minor is possible in a minor key. And 7sus4 is not the same as 7: it keeps the ♭7 but still has no third, so it sounds softer and more open.
