# Brass Instruments Uncoiled

Brass Instruments Uncoiled
Teaching Objective
Students will compare the length of objects in their environment with the extended length
of brass instruments.
Vocabulary
Predecessor - a thing that came before another
Resources
"Brass Instrument Uncoiled" chart
Pictures of a trumpet, trombone, French horn and tuba (available on the
instrument section).
Yardsticks or rulers
Dimensions of a football field - approximately 53 yards (159 ft.) wide and 100 yards
(300 ft.) long
Pre-Assessment
Display pictures of the trumpet, trombone, French horn and tuba and challenge the class to
guess the length of the tubing of each instrument.
Teaching Sequence
1.
Tell students that the oldest predecessor of brass instruments we know about is a
trumpet found in a drawing in King Tutankhamen's tomb in Egypt, dating to 1500 BC
- over three thousand years ago. The Egyptian trumpet was a long, straight tube
made of silver or bronze, and was four feet long. This instrument could produce only
a few tones. As the trumpet evolved over time, it became longer and was coiled to
make the instrument easier to hold. Later, valves and tubing were added to let the
players play all the notes in the scale.
2. Display the "Brass Instrument Uncoiled" chart, or make copies and distribute one to
each student.
Note to Teacher: Each brass instrument is found in many lengths but for the
purpose of this lesson, use the lengths found on the chart on page 12.
3. Challenge students to solve problems such as: How many trumpet lengths tall are
you? Our classroom is ___x___ ft. (let students measure the dimensions) How many
(choose an instrument) lengths is each side of the room? A football field is
____long and ____wide. How many (choose an instrument) lengths is the length?
Width?
