5. Experiment with Voicings Try extending the chord to include 7ths or 9ths (e.g., C4, E4, G4, B♆) for richer harmonic colors.

6. Transpose the Chord Shift the C major shape to different octaves and keys to understand its flexibility.

Arpeggios: Play broken C major arpeggios to enhance fluidity across surrounding chords.
Right-Hand Comping: Combine C chords with rhythmic motifs in chords, bass occlusions, or single-note patterns.
