The series of notes in the first set of bars (shown below)
will sound relatively atonal: No sense of key is clear, no sense of direction
or "connection" between the notes can be heard. One might try
to hear something, and may feel there is some interlocking commonality
between the notes, but it will not be clear and obvious.
The series below has harmonies added to the same set
of notes, which cause the notes to now sound as though they are an integrated
melody or a series of notes that flows one into another. The harmonies
delineate a sense of key, a direction leading to a cadence or suggesting
a phrase that must follow. The harmonies thus "overcome" the
otherwise disjointed series when played without any harmony
added.
To hear the melody click the score below. The music will
play first the melody without harmonies or phrasing. After a couple of
seconds, the same melody will sound out with the harmonies
added.
