Check Every Written Phrase Constraint

Supplied materials

• Paper and a pencil, typed notes or a browser scratch area. Color names can replace colored supplies; drawn figures and timelines can replace performance.
• Complete teaching inputs: Original phrase constraints: pitches between 60 and 65 inclusive, exactly 3 notes, total 2 quarter-note beats. Which supplied phrase passes all three checks? Supplied candidates: (A) pitches [59, 62, 65], durations [1, 0.5, 0.5] (B) pitches [60, 62, 65], durations [1, 0.5, 0.5] (C) pitches [60, 62, 65], durations [1, 1, 1] (D) pitches [60, 65], durations [1, 1].
• Independent check: Original phrase constraints: pitches between 61 and 66 inclusive, exactly 3 notes, total 2 quarter-note beats. Which supplied phrase passes all three checks? Supplied candidates: (A) pitches [60, 63, 66], durations [1, 0.5, 0.5] (B) pitches [61, 63, 66], durations [1, 0.5, 0.5] (C) pitches [61, 63, 66], durations [1, 1, 1] (D) pitches [61, 66], durations [1, 1].

Learn the idea

Bring structural reasoning and honest evaluation together. Audit a phrase against several constraints, interpret a nonchord tone from its supplied context, correct audiovisual cue offsets and design evidence suitable for a performance claim. A composition brief can specify pitch range, note count and total duration at once. Inspect each property independently so a phrase passing one constraint is not assumed to pass all of them.

Reason through the supplied case: The selected phrase has three pitches inside the allowed range and durations 1+0.5+0.5=2. The alternatives violate range, time or note count. Passing these structural checks does not by itself judge expressive quality or verify performed pitch and timing.

Structural validity does not establish expressive quality or accurate performance. The original exercise supplies a numeric pitch model and transparent criteria rather than a claim of expert musical achievement.

1. Read the complete teaching inputs and mark the feature, rule or constraint being tested.
2. Compare the model decision with one rejected candidate; state the visible evidence or calculation that distinguishes them.
3. Solve the independent check and the three changed-input practice cases before reading feedback.
4. Create exactly three pitches within sixty-to-sixty-five with durations totaling two quarter-note beats, then audit each condition.
5. Check your artifact against these explicit criteria: The note count is three, all pitches lie in range and the duration sum is two; the audit reports each condition separately.

Take it further

New-input analysis: Original phrase constraints: pitches between 67 and 72 inclusive, exactly 3 notes, total 2 quarter-note beats. Which supplied phrase passes all three checks? Supplied candidates: (A) pitches [66, 69, 72], durations [1, 0.5, 0.5] (B) pitches [67, 69, 72], durations [1, 0.5, 0.5] (C) pitches [67, 69, 72], durations [1, 1, 1] (D) pitches [67, 72], durations [1, 1]. Expected relationship: pitches [67, 69, 72], durations [1, 0.5, 0.5]. The selected phrase has three pitches inside the allowed range and durations 1+0.5+0.5=2. The alternatives violate range, time or note count. Passing these structural checks does not by itself judge expressive quality or verify performed pitch and timing. Create your own artifact: Create exactly three pitches within sixty-to-sixty-five with durations totaling two quarter-note beats, then audit each condition. Completion criteria: The note count is three, all pitches lie in range and the duration sum is two; the audit reports each condition separately.
