Here's why:
* Tonality refers to the organization of music around a central pitch, known as the tonic. This central tone acts as a point of reference and creates a sense of stability and direction within the music.
* The relationship between the tonic and other pitches in a piece of music is what creates the feeling of harmony, melody, and progression.
* This sense of relatedness is essential in Western music, as it helps us understand and appreciate the structure and meaning of the music we hear.
