Piano #2

Pianos create sound when the player presses a key which triggers a hammer to strike a string. When the hammer strikes the string, it causes a vibration in the string which causes the air molecules to hit each other, making a sound. At this point, a damper is released, causing the string to continue to vibrate. When the key is released, the damper stops the string from vibrating, stopping the sound. ​Pianos pitches and dynamics can be changed depending how the player plays it.The pitch can be changed by pressing a key that strikes either a thicker or thinner string. The volume can be changed by pressing the key either lighter or heavier. I could actually build this instrument by replacing the strings for xylophone bars, which would minimize the amount of materials I would need to build it. I would need wood for the casing, some felt, and various screws. The felt is for the hammer, which causes a softer sound when it hits the xylophone bar. The xylophone bars are what are going to vibrate to make the sound. The wood is used for the casing, the hammer, and the entire action. The screws are going to be used for the action. I will be playing the instrument by pressing the keys which will trigger the hammer to strike the xylophone bar. I will be going to VK's room everyday after school to build it. I will also try to schedule days when I can meet up with Quach (the member who had the highest score for access to materials) so I could build it.
