Explore and Master the C#7 Guitar Chord

The C#7 chord, C# dominant seventh, is spelled C#, E#, G# and B. The E# is the major third and is the same pitch as F, which is why the Db spelling appears as well.

Out of 11 voicings, five are barres and one uses an open string; the lowest sits at the 2nd fret. C#7 is the V7 of F# major. It fits into jazz chord progressions as a dominant that resolves up a fourth, and the C# Mixolydian scale covers its four notes.

Play it into the microphone and check that every string sounds.

C# dominant 7th guitar chord is also written as C#7, C#dom7 or C#dom.
