What is Key or Tonality?
Key or tonality is a fundamental concept in music that refers to the tonal center or home base of a piece. It provides a sense of stability and organization to the music, helping to guide the listener through the progression of harmonies and melodies.
Characteristics of Key or Tonality
Several key characteristics define key or tonality:
- Tonality: The overall impression of a key or tonality is conveyed through the arrangement of notes and chords. Major tonalities sound bright and cheerful, while minor tonalities sound darker and more somber.
- Key Center: Every key has a tonic or key center, which is the most stable note in the scale. The tonic is typically the note that the music begins and ends on.
- Scale: Each key is associated with a specific scale, which determines the pattern of whole and half steps between the notes. The most common scales are the major and minor scales.
- Chord Progression: The chords used in a piece of music often follow a specific pattern known as a chord progression. These progressions help to create a sense of movement and tension within the music.
- Leading Tone: The leading tone is the seventh note in a major scale or sixth note in a minor scale. It has a strong tendency to resolve up to the tonic, creating a sense of anticipation and resolution.
