A drum makes sound due to the vibrations of the material stretched across its hollow body. When a stick, mallet, or hand strikes down on this surface material, it begins to vibrate up and down. The vibration moves the air, creating sound waves.Know More
The sound that comes out of a drum is affected by its shape. If the drum is large, the sound will have a lower pitch. This is because the material on the top of the drum will take longer to move upward when it is struck. The slower vibration causes a lower pitch. Conversely, a drum with a small body will have a higher pitch.
In much the same way, the material covering the drum impacts the sound quality. If the material is stretched more tightly across the drum, it will vibrate more and produce a higher sound. If the material is stretched loosely, the sound will be lower.
Finally, drum sound is impacted by the way that the drum is struck. If it is struck with an open hand or wooden stick, it makes a sharp noise instantly, followed by a vibrating sound. If struck by a padded mallet, the drum will make the vibrating noise the entire time.Learn more about Musical Instruments
A violin produces sound through the vibration of its strings, which occurs when the player draws the bow over the strings and sets them in motion. From there, the bridge of the violin transmits those vibrations to the back and front plate of the instrument, causing the entire body of the violin to serve as a resonating chamber and amplifying the sound produced.Full Answer >
Saxophones produce sound by using the player's flow of air and creating an oscillating motion with the reed acting as an oscillating valve. The reed and the resonances that are present within the air inside of the instrument produces a vibrating and radiating sound out of the holes as well as the belly of the instrument.Full Answer >
The notes produced on a piano are the result of at least one string being struck with a small hammer. The strings vibrate at different frequencies to produce different notes. The string frequencies are determined by the wire used and its length, width, tension and density. The strings in pianos are made with extremely tough wire that is hard enough to chip the blades of a regular wire cutter.Full Answer >
The harp produces sound when its strings are plucked, causing the strings to vibrate and move air through space. The strings are attached to a soundboard, which also vibrates and moves air, resulting in audible sound waves.Full Answer >
