Teacher orientation
This week asks: How can different written notes represent the same sounding pitch across an ensemble? The three meetings move from shared experience to explicit theory and then transfer. Require students to predict before measuring or labeling; use performance and explanation together as evidence.
Transposing instruments are out of tune; written pitch is false; all B♭ instruments sound in the same octave.
Three-meeting sequence
Two correct labels
Separate written and concert pitch
Have a concert-pitch and B♭ player perform written C.
Define instrument key by the concert sound of written C; distinguish notation label from measured frequency.
Use the dual tuner to compare flute, clarinet, horn, alto sax, and viola labels for one sustained sound.
When B♭ trumpet plays written C, what sounds?
Complete written-to-concert translations.
Direction without guessing
Transpose for B♭, E♭, F, and A instruments
Transpose a concert melody for B♭, E♭, and F parts.
Teach both interval method and “concert to written” direction; include octave displacement for piccolo, bass clarinet, saxophones, euphonium, and bass.
Teams prepare three correctly ranged parts, then reverse-check every note to concert pitch.
Why does alto sax read A for concert C?
Finish a four-instrument score excerpt.
The conductor’s page
Read multiple clefs in open score
Project an open score with treble, alto, tenor, and bass clefs.
Establish score-order scanning, concert versus transposed score conventions, and rehearsal-pitch translation.
Students conduct a mock tuning sequence and diagnose one planted clef/transposition error.
State the sounding pitch and written pitches for today’s tuning note.
Annotate a page of full score for rehearsal.
Live dual-staff transposition laboratory
One microphone signal drives both staves. Choose any two instruments; each panel independently applies its written-pitch transposition, accidental preference, octave displacement, and treble, bass, alto, or tenor clef.
Student synthesis task
Claim–evidence–application: Students submit one notated or analytical artifact from the week, a 150–250 word explanation using at least four vocabulary terms, and a brief performance, recording, or demonstration. The explanation must identify a decision, cite musical evidence, and connect the idea to unfamiliar material.
Assessment and answer guidance
| Prompt | Value |
|---|---|
| 1. What does “instrument in B♭” mean? | 2 points |
| 2. What should an E♭ alto sax read for concert B♭? | 3 points |
| 3. Does changing the tuner instrument change the measured frequency? | 3 points |
| 4. Apply the week’s central idea to a new four-to-eight-measure example and explain the reasoning. | 7 points |
Teacher answer guidance
1. Its written C sounds concert B♭.
2. Written G.
3. No; it changes the written label and clef representation of the same sound.
4. Award 2 points for accurate identification or construction, 2 for correct notation/terminology, 2 for evidence tied to the example, and 1 for a clear conclusion. Accept alternate solutions when the musical reasoning is defensible.
Access, differentiation, and extension
Support without lowering the target
Start every conversion with written C and an interval arrow. Preteach vocabulary, model one complete think-aloud, reduce the number of simultaneous variables, and allow a second attempt after feedback.
Extension
Include A clarinet, English horn, piccolo, double bass, and transposed score traditions.
Evidence to retain
Keep the exit tickets, synthesis artifact, and scored application prompt. Together they show factual fluency, transfer, and the student’s ability to explain music—not only select an answer.
