C#7#9

— About this chord

C#7#9 (C# dominant 7 sharp 9, the 'Hendrix chord') clashes a major 3rd against a sharp 9th for a gritty, bluesy dissonance that's become a rock and funk signature. It sits comfortably as a barre chord, delivering a raunchy, unresolved punch perfect for riff-driven rhythm parts and funky turnarounds. Common as a tonic-flavored dominant in blues-rock rather than a strict V chord. Also searched as C#dom7#9, Db7#9, D♭7#9.
