This type of instrument is used by astronomers.
What is a telescope?
This is required for sound to travel.
What is a medium?

What is 440Hz?
This word means a pleasing combination of tones.
What is consonance?
This instrument has 88 keys.
What is a piano?
This is how tall the wave is from the rest position to the crest.
What is amplitude?
Sound can’t travel through this.
What is empty space?
The frequency of A5, one octave above A4.
What is 880Hz?
This term describes an unpleasant or jarring sound combination.
What is dissonance?
In a string, higher tension creates this kind of pitch.
What is a higher pitch?
Do particles in a medium travel with the wave?
What is no, they vibrate in place?
Faster vibrations result in this kind of pitch.
What is a higher pitch?
He is the inventor of the piano
Bartolomeo Cristofori
A musical “fifth” has this approximate frequency ratio.
What is 3:2?
A thicker string results in this kind of pitch.
What is a lower pitch?
These types of waves are responsible for heating food and internet signals.
What are electromagnetic waves?
Amplitude of a sound wave affects this.
What is volume?
This tuning system divides the 2:1 ratio into 12 equal parts.
What is 12-tone equal temperament?
A musical “fourth” has this ratio.
What is 4:3?
We can imagine this instrument to be a string in two dimensions.
What is a drum?
The length between two crests of a wave is called this.
What is wavelength?
Between Air, Water, and a Solid, sound travels through this.
What is a solid?
This genre of music is typically centered on the electric guitar, and the second half of the 20th century it was the world’s dominant form of music, ASHTON, LAYLA, EMY AND EASTON!
The most dissonant sound happens when two notes are this interval apart.
What is a half-step?
The part of playing a string instrument that changes the string length.
