The water bottle xylophone is played by a person striking bottles filled with different amounts of water there. The bottles are filled to specific amounts so that the waves change distance they have to travel to crash in the water. You change the notes by striking a different bottle. The note is formed when the striking of the object against the bottle shoots into the container and takes a set amount of time to disrupt the water in the bottle producing a different note. This makes me think that sound is changed and produce by sound waves interacting with a medium of different distances and tensions in order to create the unique sound. I think you can conclude that with a longer distance for the wave to travel the deeper the sound will be because the more spread out the wave will be at the point of impact.
I can play the instrument by striking the wood or glass with mallets or something along those lines.
I don't have questions really, just feedback would be great from Ms. Echols.
The instrument that I plan on playing for the benchmark is the Xylophone. The xylophone originated in Asia and Africa. It consists of bars of different lengths that can be struck by plastic, wooden, or rubber to produce sound. Bars of different lengths produce different sound. The xylophone is played by striking the bars with mallets. The bars vibrate producing sound.
The general form/shape that a xylophone is in is a rectangle or sometimes a square. To change the notes that are played on a xylophone, all you have to do is strike a different bar on the xylophone. You can change the sound by altering the density of the specific notes. This makes me think about the density of the notes and if the type of mallet matters. Also it makes me think whether hitting the bars with more force will make the sound louder. I wonder if the material of the xylophone (what its going to made of) will make a difference on the sound. The vibration of the bars when hitting them makes me think about the connection between that and the sound, and how the length matters as well.
Questions: How does the box underneath the bars amplified its volume? And why does longer bar has lower pitch? Please answer this (or show me how to find out the answer) asap, Ms. Écholsawnsome:)
2. I will change the pitch by changing the amount of water inside the glass. The more water there is in the glass, the lower the pitch will be. This is because when there is water inside the glass, some of the energy that would be pushing air molecules is moving water molecules instead. The more water there is in the glass, the more energy is diverted to moving the water instead of the air. This creates a lower pitch.
3. I will be using a set of cheap wine glasses glued to a simple surface like a piece of wood, to keep all the glasses together and safe. I will pour different amounts of water into each glass to achieve different notes. I will play the instrument by tapping different glasses to produce different sounds.
4. How can I precisely measure the amount of water to put in each glass so that I can achieve specific notes? Should I be careful to tap each glass in the same specific place?
I was thinking about doing piano at first. Pretty sure I'm going to make either a xylophone or a twanger to make matters easier. Sound is produced with the xylophone by hitting on the keyboard of different sounds and pitches. The longer the rod the more mass it has where as to a shorter rod it'll have a more pitch sound.
2. Based on your understanding, how are you changing the pitch? What physical characteristics are important in this instrument?
It depends on the length and width of the rod to create the sound.
3. What materials will you actually be using for your instrument and why? How will you play your instrument? What is your plan for constructing the instrument?
I planned on using metal plates to use as the keyboard and a box to have a base for the plates. From my understandings, the length and width of the rod will have more of an effect in constructing the instrument I would like to play.
4. What outstanding questions do you still have?
Am I on the right path Ms. Awesome?
