C# Mixolydian Mode
Major scale with flat 7th - bluesy sound
What is the C# Mixolydian Mode?
Mixolydian is the fifth mode of the major scale — the major scale started from its 5th degree. Compared to the major scale, it lowers the 7th by a half step (b7), which is exactly what makes a dominant 7 chord dominant. The result is a major-feeling scale with a built-in bluesy edge, ideal for any progression centered on a I7 chord.
Notes in the scale: C# – D# – F – F# – G# – A# – B
Intervals: Root, 2, 3, 4, 5, 6, b7 (measured from the root)
Parent key: F# major — shares the same seven notes

When to use the C# Mixolydian Mode
C# Mixolydian Mode draws its notes from F# major, starting on C#. Use Mixolydian over a static dominant 7 vamp — think Grateful Dead jams, AC/DC choruses ('You Shook Me All Night Long'), most Allman Brothers solos, and any country or rock progression that hangs on the V chord without resolving. Mixolydian is also the modal home of bagpipe music and many Celtic tunes.
