Answer 1

The essential elements of any melody are duration, pitch, and quality [timbre, texture, and loudness].

The melodies in most European music written before the 20th century features recurring "events, often periodic, at all structural levels" and "recurrance of durations and patterns of durations" are also important in 20th century music.

While in the 20th century pitch includes those aspects of sound that are classed as having higness or lowness earlier music included almost exclusively sounds having fixed and easily discernible frequency patterns and composers have utilized a greater variety of pitch resources than has been the custom in in any other historical period of Western music. While materials from the diatonic scale are still used, the twelve-tone scale became widely employed.

Melodies in the 20th century where increasingly reliant "upon the qualitative dimensions" with those dimensions "taking on roles that in pre-twentieth century music were almost exclusively reserved for pitch and rhythm" such as being an "element of linear ordering" rather than a highlight to "the more predominant pitch and rhythmic aspects." See Klangfarbenmelodie and Musique concrète.
