About this note
C♯ (enharmonic with D♭) is the second note of the chromatic scale, one semitone above C. It is the root of C♯ major / D♭ major — common in jazz and used as a transposition target.
Tips for memorizing
Start with the lowest fret on each string. Notice the octave shapes — the same note repeats every 12 frets along a single string. Across strings, octaves form predictable visual shapes (e.g., 2 strings down + 2 frets up).
Try the interactive trainer to drill C♯ until it becomes automatic. Most learners get all six strings comfortable within a week of 5-minute daily sessions.
