Melodic motion
Melodic motion motion is the quality of movement of a melody, including nearness or farness of successive pitches or notes in a melody. This may be described as conjunct or disjunct, stepwise, skipwise or no movement, respectively. See also contrapuntal motion. In a conjunct melodic motion, the melodic phrase moves in a stepwise fashion; that is the subsequent notes move up or down a semitone or tone, but no greater. In a disjunct melodic motion, the melodic phrase leaps upwards or downwards; this movement is greater than a whole tone.
In popular Western music, a melodic leap of disjunct motion is often present in the chorus of a song, to distinguish it from the verses and captivate the audience.
Bruno Nettl describes various types of melodic movement or contour :
- Ascending: Upwards melodic movement
- Descending: Downwards melodic movement
- Undulating: Equal movement in both directions, using approximately the same intervals for ascent and descent
- Pendulum: Extreme undulation that covers a large range and uses large intervals is called pendulum-type melodic movement
- Tile, terrace, or cascading: a number of descending phrases in which each phrase begins on a higher pitch than the last ended
- Arc: The melody rises and falls in roughly equal amounts, the curve ascending gradually to a climax and then dropping off
- Rise: may be considered a musical form, a contrasting section of higher pitch, a "musical plateau".
Other examples include:
These all may be modal frames or parts of modal frames.
