F13

— About this chord

F13 (1-3-5-♭7-9-13) stacks the dominant 7th with a bright, rolling 9th and 13th color, giving a rich, jazzy sweetness over blues and funk grooves. A staple of big-band voicings and soul-jazz comping, it works as a colorful substitute for a plain F7 in turnarounds and vamps, implying the full extended dominant sound in just a few notes. On guitar it's commonly played as a compact low-string shape or an A-string-rooted grip further up the neck. Often used as the V chord resolving to Bb, or as a static groove chord in funk and blues-rock. Also searched as Fdom13 or F dominant 13.
