C♯ has the stable, upbeat sound of every major triad. Major chords are the backbone of most songs; C♯ is home in C♯ major and a common IV or V in the keys around it. Play it solid and then broken to hear the difference.

Play C♯ broken, one key at a time: C♯, E♯, G♯, E♯, C♯. Then press the keys together and check that all 3 sound at the same volume. Finish with the inversions in order: C♯–E♯–G♯; E♯–G♯–C♯; G♯–C♯–E♯.
