Short answer

Added ninth chords are open and shimmering. Unlike a ninth chord they leave the seventh out, so the added second degree colours the triad without any of the tension a dominant brings, a favourite of pop and worship guitarists.

How to use the C♭add9 chord

The C♭add9 chord is built from a root, a major third, a perfect fifth and a major ninth. Start at the root C♭ and stack the intervals to get the whole chord: C♭, E♭, G♭ and D♭. The same formula gives you the chord in any other key.

Added ninth chords replace plain major chords when a part needs air, especially in fingerpicked guitar and piano pads. They are everywhere in pop ballads, worship music and indie rock.

How C♭add9 differs from similar chords

C♭add9 adds a ninth to C♭ and leaves the seventh out, which is exactly what separates it from C♭9 and C♭maj9. Unlike C♭sus2, it keeps the major third, so it stays clearly major. The ninth is the same note as the second, only an octave higher.

Where C♭add9 is used

A major chord is at home as a tonic, and just as useful as the IV or the V of a neighbouring key. Each progression below is written in the key its numerals name.
