Melody
Definition:
(n.) A sweet or agreeable succession of sounds.
(n.) A rhythmical succession of single tones, ranging for the most part within a given key, and so related together as to form a musical whole, having the unity of what is technically called a musical thought, at once pleasing to the ear and characteristic in expression.
(n.) The air or tune of a musical piece.
Example Sentences:
(1) Moments later, Strauss introduces the bold human character with an energetic, upwards melody which he titles "the climb" in the score.
(2) There’s an interesting thing with music like this, how the beat falls with the melody; they often say music is mathematical in construction and this is a very good example.
(3) A psychophysical scaling procedure confirmed that the constraints generated tone sequences bearing degrees of perceptual similarity to "real" melodies.
(4) A model of how people use this information to infer the metre of unaccompanied melodies is described here.
(5) Young children also are sensitive to melodic contour over transformations that preserve it (Study 5), yet they distinguish spontaneously between melodies with the same contour and different intervals (Study 4).
(6) We also know little about the relative aptitude for different musical components, especially melody and harmony.
(7) He presented a right-ear extinction in dichotic tasks, as well as difficulties in understanding and repeating verbal material and impaired identification of melodies.
(8) But the album for which she is being rightly acclaimed, 50 Words for Snow, as well as cleverly weaving together some hauntingly beautiful melodies with a characteristically surrealist narrative, also perpetuates a widely held myth about the semantic capaciousness of the Inuit language.
(9) The fact that "different" responses were both faster than "same" ones and quicker than melody offset indicates the use of a self-terminating search process.
(10) Particular tones were shifted in sequence such that a melody was heard which was undetectable by either ear alone.
(11) Children 4 to 6 years of age were exposed to repetitions of a six-tone melody, then tested for their detection of transformations that either preserved or changed the contour of the standard melody.
(12) The key distance effect reported in the literature did not occur in the tasks of this investigation (Studies 1 and 3), and it may be apparent only for melodies shorter or more impoverished than those used here.
(13) All subjects had high DAF indices on the complex melody, middle on the medium and low on the simple.
