The Dominant Thirteenth Suspended 4th Chord (or Dominant 13sus4) is a very extended, complex, and nuanced chord. The notes are: root, perfect fourth, perfect fifth, minor seventh, major ninth, and major thirteenth. Its sound is lush, open, and 'airy', combining the ambiguity and suspension of the fourth with the fullness and sophistication of the ninth and thirteenth extensions. It is a chord of choice in jazz, fusion, and neo-soul for creating sophisticated and 'airy' harmonies. The suspended fourth gives it a less directly resolving character than a 'normal' Dominant 13, but the presence of the extensions maintains its fundamental dominant function. The fifth is often omitted in guitar voicings to ensure clarity and ease of execution, focusing attention on the extensions.
