What's the difference between diatonic and septenary?

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.

Septenary


Definition:

  • (a.) Consisting of, or relating to, seven; as, a septenary number.
  • (a.) Lasting seven years; continuing seven years.
  • (n.) The number seven.
