Review: Scale Spelling, Interval Identity, Voice Motion, and Cues

Use multiple pieces of score information together. Retain supplied scale spellings, combine generic and chromatic interval distances, compare fixed-voice movement costs and synchronize an original audiovisual cue plan.

Unit review questions
1. The supplied F major scale spelling is ['F', 'G', 'A', 'Bb', 'C', 'D', 'E', 'F']. Number degrees 1–8. Which note is degree 5?
Need a hint?
  • A supplied scale spelling pairs each degree with a note letter and any accidental.
  • A pitch-class number alone can hide enharmonic spelling.
2. Supplied upward interval E→B spans 5 letter positions inclusively and 7 semitones. Use the given classification: third 3=m3, third 4=M3, fourth 5=P4, fifth 7=P5, sixth 8=m6, octave 12=P8. Which fits?
Need a hint?
  • A specific written interval uses both inclusive letter distance and chromatic distance.
  • Enharmonically related endpoints can have the same pitch distance but different written interval identities.
3. Three fixed voices begin at pitch-numbers[65, 69, 72]. Which supplied voicing of the target pitch classes minimizes the sum of each voice’s absolute pitch movement?
Need a hint?
  • For this limited arrangement criterion, keep each voice’s identity fixed and add its absolute pitch movement.
  • Minimum total motion is one explicit criterion, not a complete set of style-specific voice-leading rules.
4. Original audiovisual plan: show the new image at second 9, begin its sound at that same cue, and hold both for 4 seconds. Which cue row is synchronized?
Need a hint?
  • A synchronized cue plan gives image and sound the same start and explicitly accounts for their duration.
  • An accurate timeline plan is not proof of actual playback synchronization.

Use the skills in a new task

Complete this four-part arts evidence sheet. 1. The supplied Eb major scale spelling is ['Eb', 'F', 'G', 'Ab', 'Bb', 'C', 'D', 'Eb']. Number degrees 1–8. Which note is degree 7? Supplied candidates: (A) C (B) D (C) E (D) F. Then Write the supplied G-major sequence G,A,B,C,D,E,F-sharp,G and label degrees four and seven. Criteria: Degree four is C and degree seven is F-sharp, with the accidental retained. 2. Supplied upward interval C→C above spans 8 letter positions inclusively and 12 semitones. Use the given classification: third 3=m3, third 4=M3, fourth 5=P4, fifth 7=P5, sixth 8=m6, octave 12=P8. Which fits? Supplied candidates: (A) major third (B) minor third (C) perfect fourth (D) perfect octave. Then Compare C-to-E and C-to-E-flat using their shared generic third and their four- versus three-semitone distances. Criteria: The first is a major third and the second a minor third, justified by both quantities. 3. Three fixed voices begin at pitch-numbers[67, 71, 74]. Which supplied voicing of the target pitch classes minimizes the sum of each voice’s absolute pitch movement? Supplied candidates: (A) [54, 59, 62] (B) [54, 83, 86] (C) [66, 71, 74] (D) [78, 83, 86]. Then Compare transitions from sixty/sixty-four/sixty-seven to sixty/sixty-five/sixty-nine and to its all-voices-up-octave version. Criteria: The first motion cost is three semitones; the octave-shifted candidate has a larger cost under the fixed-voice model. 4. Original audiovisual plan: show the new image at second 11, begin its sound at that same cue, and hold both for 3 seconds. Which cue row is synchronized? Supplied candidates: (A) Both start 11; both end 15 (B) Both start 12; both end 15 (C) Image and sound start 11; both end 14 (D) Image starts 11; sound starts 12; both end 14. Then Plan image and sound to start together at second five and last three seconds. Criteria: Both begin at five and end at eight; the shared cue and duration are explicit.

Work on paper or in your own document. Explain the choices you made.

  • Answer each supplied changed-input analysis with its visible evidence, rule or calculation.
  • Include the original artifact required for each lesson; paper/text equivalents are acceptable.
  • Apply the stated criteria and document one concrete revision.
  • Describe planning/analysis accurately; do not claim unobserved musical, acting or dance execution.
Compare with a model response

1. D. Count inclusively from tonic Eb as degree 1. Degree 7 is list position 6, spelled D, retaining its accidental. These supplied spellings follow the Western major pattern; a note-name change can alter the written interval identity. An original artifact is acceptable when Degree four is C and degree seven is F-sharp, with the accidental retained. 2. perfect octave. Use both quantities: generic number 8 and chromatic distance 12. Together they match perfect octave in the supplied classification. A semitone count alone can describe enharmonically spelled intervals with another generic number, so retain the written endpoints. An original artifact is acceptable when The first is a major third and the second a minor third, justified by both quantities. 3. [66, 71, 74]. The chosen movements are [1, 0, 0], summing to 1. Moving entire voices an octave adds much larger distances for the supplied alternatives. This criterion concerns total motion only; it does not certify every style-specific voice-leading rule. An original artifact is acceptable when The first motion cost is three semitones; the octave-shifted candidate has a larger cost under the fixed-voice model. 4. Image and sound start 11; both end 14. Start times match at 11. Duration 3 gives end time 11+3=14. A shared cue and explicit end time make the intended relationship testable; actual playback synchronization would still require rendered or performed verification. An original artifact is acceptable when Both begin at five and end at eight; the shared cue and duration are explicit.

A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
