Explanation:
Ascending: Upwards melodic movement
Descending: Downwards melodic movement (prevalent in the New World and Australian music)
Undulating: Equal movement in both directions, using approximately the same intervals for ascent and descent (prevalent in Old World culture music)
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 (prevalent in the North American Plain Indians music)
Arc: The melody rises and falls in roughly equal amounts, the curve ascending gradually to a climax and then dropping off (prevalent among Navaho Indians and North American Indian music)
Rise: may be considered a musical form, a contrasting section of higher pitch, a "musical plateau".
Other examples include:
Double tonic: smaller pendular motion in one direction
These all may be modal frames or parts of modal frames.
