What are chromatic notes?

Chromatic notes are those that do not belong to the established key of the composition. They are typically found by moving in half steps, which means that they add colors and tension to the music as they introduce pitches that are not traditionally used in the scale based on the key signature. This concept allows composers and performers to create a more complex harmonic structure and enhances the emotional expression of the piece.

Notes that fit within the key of the composition establish a diatonic framework, while high-pitched notes can occur within or outside the key. Repeated notes also do not define chromaticism but rather focus on the rhythmic aspect of the music. Detailed understanding of chromatic notes can greatly enhance one's appreciation for music theory and composition.
