What's the difference between diatonic and octave?

Diatonic


Definition:

  • (a.) Pertaining to the scale of eight tones, the eighth of which is the octave of the first.

Example Sentences:

  • (1) In Experiment 1, children from 4 to 6 years of age were superior in detecting the semitone change in the diatonic context compared with the nondiatonic context.
  • (2) The factors were distance in pitch height from the context tones, octave equivalence, and the following hierarchy of tonal functions: tonic tone, other tones of the major triad chord, other tones of a diatonic scale, and the nondiatonic tones.
  • (3) In Experiment 2, infants 9 to 11 months of age detected the semitone change in all positions, but their performance was not influenced by diatonic context.
  • (4) The sequence consisted of a series of frequent standard C5 tones from the diatonic musical scale, in which three deviants (F #5, C6, and F #6) and a target (C4) were occasionally embedded.
  • (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.
  • (9) Two standard melodies were used, one composed of diatonic tones only and the other containing a non-diatonic tone.
  • (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 eighth tone in the scale; the interval between one and eight of the scale, or any interval of equal length; an interval of five tones and two semitones.
  • (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.
  • (20) Chinchillas were exposed to an 86 dB SPL octave band of noise centered at 4.0 kHz for 3.5--5 days.
