The C# sus 4 chord (C sharp suspended 4) contains the notes C#, F# and G#. It is produced by taking the 1 (root), 4 and 5 of the C# Major scale. It is essentially a C# Major chord, with the 3rd (E#) taken out and the 4th (F#) added in.

By omitting the 3rd and adding the 4th, the chord feels ‘suspended‘. The 4th creates a feeling of tension, which feels resolved when the chord moves to the standard Major chord (bringing the 3rd back in). To demonstrate this, try the following chord progression:

C# Major – C# sus 4 – C# Major

Just by strumming those three chords once each, you will hear the the tension that is created by moving to the C# sus 4 chord. You will also hear the resolution that is created by moving from the sus chord back to the Major chord.

C# sus 4 is often used as a way of adding flavour to the C# Major chord. The C sharp sus 4 chord is often substituted momentarily, when playing the C# chord, to create a quick sense of musical movement and interest.
