The Dorian mode is characterized by a specific tonal quality and melodic contour. Here's a breakdown of its key features:
1. Tonal Center: The Dorian mode revolves around a tonal center, which is the tonic or principal note of the mode. In the Dorian mode, the tonic is the second (II) degree of the major scale.
2. Interval Structure: The Dorian mode consists of the following interval sequence: Whole tone - Half tone - Whole tone - Whole tone - Half tone - Whole tone - Half tone. This pattern creates a unique melodic feel that distinguishes the Dorian mode from other modes.
3. Signature: The Dorian mode has a distinctive major sixth (M6) between the tonic and subdominant (IV degree) notes. The presence of this major sixth is what gives the Dorian mode its characteristic sound.
4. Modal Formula: The Dorian mode can be represented by the following modal formula: T - T+2 - T+3 - T+5 - T+7 - T+9 - T+10.
5. Melodic Characteristics: The Dorian mode often features melodic lines that emphasize the tonic, second, and sixth degrees. Melodies in the Dorian mode tend to have a warm, somber, and reflective quality.
6. Musical Applications: The Dorian mode is widely used in various genres of music, including folk music, early medieval music, Celtic music, jazz, and modern popular music. Some famous examples of Dorian melodies include the traditional Scottish folk song "The Skye Boat Song" and the jazz standard "So What" by Miles Davis.
Understanding the Dorian mode and its characteristics allows musicians and composers to create unique melodies and harmonies with a specific emotional impact and tonal color.
