My instrument uses an Arduino (the circuit board in the center)  to generate sound waves by oscillating pin 2 at specific frequencies. Each of the keys are connected to pins 3 through 10 on the Arduino. The USB connection is just for power. The connection in the top left is the audio output.

My instrument makes sound because the beads hit the sides of the card board and creates sound waves. When you shake the maraca harder, the more sound generated.

My instrument makes soundwaves when I pluck the "strings" and it vibrates. If you change your sound to a high frequency , the pitch also gets higher. Same with a low frequency, the pitch gets lower. If your sound is high, it has a high frequency and a short wavelength. If the wavelength is long, you have a low frequency and a lower sound.

My instrument creates sound when the chopsticks hit the cans or containers. This results in the drum vibrating the air around it. When you increase the amplitude you make the sound louder, but if you decrease the amplitude you make the sound softer or quieter. Increasing the wavelength makes the pitcher lower, and decreasing the wavelength makes the pitch higher.

My instrument makes sound waves when you pluck the rubber bands. The rubber bands then vibrate and so do the air particles. The vibration of the air particles allows the sound waves to travel. To increase/decrease the wavelength and amplitude for the instrument you can use rubber bands of different elasticity and width. This also affects the sound the rubber bands make when plucked. When I increase the amplitude, the sound will increase as well. Alternatively, when I decrease the amplitude, the sound will decrease as well. When I increase/ decrease the wavelength, it affects the frequency which, in turn, affects the pitch of the sound.

My instrument makes sound waves when the rubber band is plucked. The plucking causes the string to vibrate which makes the air molecules around the source of the sound also vibrate. These vibrations have compressions and rarefactions and a pattern of compressions and rarefactions would make a sound wave. Increasing/ Decreasing the wavelength would result in the change of the sound's pitch. And  Increasing/ Decreasing of the amplitude would result in the change of the sound's volume.

My instrument is “Brianna's Brilliant Band of Bands”.  The instrument has bands at different lengths up and down the body of the instrument, and those bands are at different degrees of tightness around the body, impacting the wavelengths and, therefore, varying the sound.  When one of the bands on the Brilliant Band of Bands is plucked with a tool or finger, waves are created and sound made.   The sound is impacted by the frequency and wavelengths.  As frequency increases, the wavelength is shorter; conversely, when frequency decreases, the wavelength gets longer.

My instrument I made is a drum with sticks! The sound is produced by hitting the top part of the drum (the red) with the red tip of the drum sticks.  The sound waves are created by the vibrations of the balloon material stretched across the cyan can. When a stick, strikes down on the red material, it begins to vibrate up and down. The vibration moves the air, this is how sound waves are produced. Increasing the amplitude makes the pitch louder. On the other hand, when I decrease the amplitude the sound gets quieter.

I made my instrument buy making the main part of of clay and foil the inside is filled with plastic beads. I used spoons for the handles.  My instrument makes sound waves when I shake it this happens because the plastic beads on the inside are hitting the foil and causing vibration which causes sound. When I increase the amplitude, the sound gets louder (to do this I would shake the instrument with more force.) Alternatively, when I decrease the amplitude, the sound gets quieter (I would shake the instrument with less force.
When you increase the wavelength, an increase happens to the sound. When I decrease the wavelength, decrease happens to the sound. Therefore wavelength and sound are related.

My instrument was made in a time crunch. It makes a sound when a drum stick is beaten on top of it. The sound varies from drum to drum, since they are cups with different amounts of water in them. The purple drum has a much greater amplitude than the other two because it has the most air, or least water in it. The less air there is in the drum, the lower the amplitude and the lower the sound. The more air there is, the higher the amplitude and the higher the sound. This happens because the sound waves underwater get trapped the immense amount of particles underwater. Sound waves also travel much faster underwater, so the glass with the most water has a very blunt, quick sound.

# data[].attributes.body
My instrument creates soundwaves when the sticks hit the drum set, once you use force for the collision. If i increase the amplitude, the volume of the sound gets higher, Once i decrease the amplitude the volume will get quieter. Therefore, when you increase or decrease the wave length the pitch of the sound will change. When you change the sound to a higher frequency the pitch/tone of the sound will also get higher. Same thing for quieter.
