What chord is C M?
Since C#m is a minor chord, you’d use the minor chord formula to build your chord, combining the root note, minor 3rd, and perfect 5th. Your root note, C#, will be the starting point of your scale. From there, add your minor 3rd (E), and your perfect 5th (G#). To play the C#m chord, you’ll play C#, E, and G# together.
