The C#m chord
Think of the C#m as an everyday minor with body. The chord is built from C# - E - G#, a textbook minor triad. It does its strongest work in any minor-key songbook, where it tends to frame a confession. The C#m does its work quietly. The brooding centre of Boulevard of Broken Dreams and Beat It. Voicings on both instruments, theory in plain language, progressions in multiple keys and a handful of real song references are all laid out below.

Guitar , triad shapes
