Tonal relationships refer to the way different musical notes or chords interact with each other in terms of their pitch and harmony. These relationships can create feelings of tension, resolution, or movement within a piece of music. For example, the relationship between the tonic and the dominant chords is crucial in establishing a sense of stability and direction in Western music. In addition to major and minor tonalities, tonal relationships can also involve modes, such as Dorian or Mixolydian, which provide different emotional colors. Understanding these relationships helps musicians and composers create more expressive and cohesive works, enhancing the overall listening experience.
