C# Major on the Guitar Fretboard
Every note of the C# major scale carries a sharp: C#, D#, E#, F#, G#, A# and B#. E# is simply F and B# is simply C, so the spelling looks heavy even though the fingering is the same as in any major key.
Many players read this key as Db major, which needs five flats instead of seven sharps. The root is on the 9th fret of the low E string and the 4th fret of the A string. If E# and B# trip you up, check the notes on the fretboard.

Structure
C# major scale notes:
How the major scale is built:
The major scale is built from the degrees 1 2 3 4 5 6 7, which gives the step pattern W-W-H-W-W-W-H (W = whole step, H = half step).
Counting in semitones from the root: 0, 2, 4, 5, 7, 9, 11. That makes it a 7-note scale.
It is the parent scale of its own modal family.
It is also known as Ionian.
