(5) They were tested for their detection of two types of changes to that melody: (a) a 4-semitone change in 1 note that remained within the key and implied dominant harmony (diatonic change) or (b) a 1-semitone change in the same note that went outside the key (nondiatonic change).
(6) Adults easily detected the nondiatonic change but had difficulty with the diatonic change.
(7) These findings indicate that infants and children can discriminate a semitone in a musical context and that the priority of diatonic structure emerges by 4 to 6 years of age.
(8) In the present research we examined the development of sensitivity to two musical relations significant in Western tonal music, the semitone and diatonic structure.

(10) Analysis of responses to melodies in each of the 24 major and minor keys indicated sensitivity to aspects of diatonic structure exhibited by mature listeners.
(11) Listeners rated test tones falling in the octave range from middle to high C according to how well each completed a diatonic C major scale played in an adjacent octave just before the final test tone.
Octave
Definition:
(n.) The eighth day after a church festival, the festival day being included; also, the week following a church festival.

(n.) The whole diatonic scale itself.
(n.) The first two stanzas of a sonnet, consisting of four verses each; a stanza of eight lines.
(n.) A small cask of wine, the eighth part of a pipe.
(a.) Consisting of eight; eight.
Example Sentences:
(1) In the postsynaptic layers, frequencies up to three octaves from the neurons' best frequency induced two-tone suppression that was sensitive to BIC.
(2) In V1, 68% of the neurones exhibited low-pass temporal tuning characteristics and 32% were very broadly tuned, with a mean temporal frequency full band width of 2.9 octaves.
(3) The torus also received bilateral input from the nucleus ventromedialis thalami, nucleus of lemniscus lateralis, nucleus medialis, anterior octaval nucleus, descending octaval nucleus, and the reticular formation.
(4) She grew up in St Louis, Missouri, more impressed as a young girl by Mariah Carey's multi-octaves and Lauryn Hill.
(5) Two component tones of each stimulus were approximately an octave apart.
(6) Average half-width (at half-height) of the spatial-frequency tuning curves constructed from the data was 1.4 octaves, and was not dependent upon the level of adaptation or the spatial frequency of the test grating.
(7) The limited data from diplacusis measurements and octave adjustments suggest that the exaggerated negative pitch shifts are the consequence of a large increase in pitch at low stimulus levels which "recruits" at higher levels.
(8) When comparing conventional octave audiometry and Békésy threshold tracing, the latter method is found to be more subtle in finding carriers of genes for recessive deafness.
(9) 4) There is a disproportionately large cortical surface representation of the highest-frequency octaves (basal cochlea) within AI.
(10) Bursts of one-third octave noise with center frequencies of 500, 1000, 2000, and 4000 Hz and durations of 15, 20, 50, 100, 200, and 300 msec were used as stimuli.
(11) The pars lateralis and rostral anterior octaval nucleus may be additional afferent sources.
(12) In Experiment 2, 2-point threshold-duration functions were compared for 4-kHz tones and octave-band noise bursts presented in backgrounds of quiet and continuous noise.
(13) Optimum filter bandwidth was found to be about 1.1 octaves.
(14) It was found that the neurons could respond well to single octaves of the spatial frequencies normally present in faces, that the most effective bands were 4-8, 8-16 and 16-32 cycles per face (cpf), and that the bands 2-4 and 32-64 cpf were partly effective.
(15) In the two experiments reported here, subjects performed repeated octave adjustments for pairs of simultaneous and successive tone bursts.
(16) One-third octave band frequency analysis of the weighted signals indicated that the dominant frequencies were usually 1.6 to 3.15 Hz, except when the vehicles were idling and higher frequencies predominated.
(17) Results varied by no more than one octave in 79 per cent of the cases.
(18) Speech and noise are both spectrally shaped according to the bisector line of the listener's dynamic-range of hearing, but with the noise in a single octave band (0.25-0.5 or 0.5-1 kHz) increased by 20 dB relative to this line.
(19) It is shown that phase-locking begins to decline at about 600 Hz and is no longer detectable above 3.5 kHz which is about 1 octave lower than in the cat, squirrel monkey and some birds.
