Shift Every Pitch by the Same Amount

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 pitch-number motif[48, 50, 53] is transposed upward by 1 semitone while durations stay unchanged. Which new pitches preserve every interval? Supplied candidates: (A) [47, 49, 52] (B) [49, 50, 53] (C) [49, 51, 54] (D) [54, 51, 49].
• Independent check: Original pitch-number motif[49, 51, 54] is transposed upward by 2 semitones while durations stay unchanged. Which new pitches preserve every interval? Supplied candidates: (A) [47, 49, 52] (B) [51, 51, 54] (C) [51, 53, 56] (D) [56, 53, 51].

Learn the idea

Use a supplied musical or dramatic context to justify an analysis. Locate accents between pulses, compare triad offsets, transpose a motif consistently and connect a spoken line with its fictional character action. Transposition adds one pitch offset to every note in the supplied numeric motif. Equal shifts preserve the neighboring pitch distances while the original duration pattern remains unchanged.

Reason through the supplied case: Add 1 to each pitch: [49, 51, 54]. Adjacent distances stay 2 and 3 because the same shift cancels in subtraction. Reversing order or changing one pitch would alter the original interval pattern.

This task uses semitone-number transposition and retains rhythm. Written note spelling and instrument range may require additional choices in a real score, so do not claim those checks were performed.

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. Transpose pitches sixty, sixty-two and sixty-five upward three semitones, retaining durations one, half and half.
5. Check your artifact against these explicit criteria: New pitches are sixty-three, sixty-five and sixty-eight, and their differences and durations match the original relationships.

Take it further

New-input analysis: Original pitch-number motif[55, 57, 60] is transposed upward by 3 semitones while durations stay unchanged. Which new pitches preserve every interval? Supplied candidates: (A) [52, 54, 57] (B) [58, 57, 60] (C) [58, 60, 63] (D) [63, 60, 58]. Expected relationship: [58, 60, 63]. Add 3 to each pitch: [58, 60, 63]. Adjacent distances stay 2 and 3 because the same shift cancels in subtraction. Reversing order or changing one pitch would alter the original interval pattern. Create your own artifact: Transpose pitches sixty, sixty-two and sixty-five upward three semitones, retaining durations one, half and half. Completion criteria: New pitches are sixty-three, sixty-five and sixty-eight, and their differences and durations match the original relationships.
