Study guide: 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.
Ideas to explain in your own words
- A supplied scale spelling pairs each degree with a note letter and any accidental. Count from the tonic as degree one and retain the complete written note when identifying a later position. A pitch-class number alone can hide enharmonic spelling. This exercise supplies Western major-scale spellings and does not claim that one scale framework covers all musical traditions.
- A specific written interval uses both inclusive letter distance and chromatic distance. Compare that pair with the supplied classification rather than selecting from semitone count alone. Enharmonically related endpoints can have the same pitch distance but different written interval identities. Preserve spelling, direction and the supplied octave context.
- For this limited arrangement criterion, keep each voice’s identity fixed and add its absolute pitch movement. Compare candidate voicings by total movement without swapping voice assignments. Minimum total motion is one explicit criterion, not a complete set of style-specific voice-leading rules. Instrument range, parallels and expressive function would need separate stated checks.
- A synchronized cue plan gives image and sound the same start and explicitly accounts for their duration. Add start time and hold length to determine the planned shared end. An accurate timeline plan is not proof of actual playback synchronization. Retain a real rendered or performed check before reporting a successful audiovisual execution.

A worked review example
Retain Spelling When Naming a Scale Degree: The supplied C major scale spelling is ['C', 'D', 'E', 'F', 'G', 'A', 'B', 'C']. Number degrees 1–8. Which note is degree 4? Supplied candidates: (A) C (B) D (C) E (D) F. Model reasoning: Count inclusively from tonic C as degree 1. Degree 4 is list position 3, spelled F, retaining its accidental. These supplied spellings follow the Western major pattern; a note-name change can alter the written interval identity. Combine Letter Count and Semitone Distance: Supplied upward interval C→E spans 3 letter positions inclusively and 4 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 fifth (D) perfect fourth. Model reasoning: Use both quantities: generic number 3 and chromatic distance 4. Together they match major third in the supplied classification. A semitone count alone can describe enharmonically spelled intervals with another generic number, so retain the written endpoints. Compare Fixed-Voice Movement Costs: Three fixed voices begin at pitch-numbers[60, 64, 67]. Which supplied voicing of the target pitch classes minimizes the sum of each voice’s absolute pitch movement? Supplied candidates: (A) [48, 53, 57] (B) [48, 77, 81] (C) [60, 65, 69] (D) [72, 77, 81]. Model reasoning: The chosen movements are [0, 1, 2], summing to 3. 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. Schedule Matching Image and Sound Cues: Original audiovisual plan: show the new image at second 4, begin its sound at that same cue, and hold both for 2 seconds. Which cue row is synchronized? Supplied candidates: (A) Both start 4; both end 7 (B) Both start 5; both end 7 (C) Image and sound start 4; both end 6 (D) Image starts 4; sound starts 5; both end 6. Model reasoning: Start times match at 4. Duration 2 gives end time 4+2=6. A shared cue and explicit end time make the intended relationship testable; actual playback synchronization would still require rendered or performed verification.
Make a practice plan
- Inspect the supplied descriptions, notation or timeline before making an interpretation.
- Solve each independent case, then explain the specific evidence behind a correction.
- Produce the original paper/text artifacts and retain one criterion-based revision.
- Attempt the unit review and exam with their new inputs; performance remains optional and separately observed.
