C# Whole-Half on the Fretboard
The correct spelling of the C# whole-half scale is C#, D#, E, F#, G, A, A# and B#, though B# is the C you actually play.
Anchor the root on the 9th fret of the low E string, then use the 4th fret of the A string for a second shape. C#, E, G and A# are the four roots that give this pitch set, so the next position is only three frets away.

Structure
C# whole-half scale notes:
How the whole-half scale is built:
The whole-half scale is built from the degrees 1 2 b3 4 b5 b6 6 7, which gives the step pattern W-H-W-H-W-H-W-H (W = whole step, H = half step).
Counting in semitones from the root: 0, 2, 3, 5, 6, 8, 9, 11. That makes it a 8-note scale.
It is also known as Diminished Scale (Whole-Half).
