About C# major
C# major is built from three notes: C# (root), E# (major third) and G# (perfect fifth). In scale degrees above the root, the formula is 1 – 3 – 5. It is a major chord: it sounds stable and bright, and it is the foundation of most chord progressions.
C# major has 4 common voicings, based on the C, A, G and E shapes of the CAGED system. There are 23 more voicings sorted by difficulty; use the viewer switches to add inversions and stretches. Another way to write C# major is Db major (the same piano key, with a different name). The usual choice is Db major.
