C Ionian
C is often associated with purity, simplicity, and innocence. It's considered an 'open' key, bright and direct.
The Ionian mode, also known as the major scale, has a bright, happy, and stable sound. It's often associated with feelings of joy, triumph, and positivity.
The I (tonic), IV (subdominant), and V (dominant) chords are particularly important in establishing the mood of this mode.
