for my first attempt at making the instrument, I tried to find things/rubbish that make loud sounds. 

The instrument was made out of a bottle, some smaller can caps and a chip bag. 

I played around with the things I have and tried how many different sounds.

for example, I cut the bottle and put cab from cans into the chip bag.

I have combined a few things together and seeing what combination it can make with it. 

having both sounds at the sound same time, it didn't sound good at all, the conclusion I got out of the first try was in my opinion an instrument is sound that can be controlled and played around with, not random noise altogether.

After getting the conclusion from the first instrument I decided not to improve my first one but to think of a better idea for my second instrument.

I was thinking about making a string instrument that is played like a guitar or guzheng, because It's more in control whether what sound will be played.

after giving it a try at making the instrument, the rubber band wasn't stretched out enough so it produced as much sound as I would have hoped.

In my quest to amplify the sound, I ingeniously utilized cut chopsticks to extend the stretch of the elastic band, exceeding my initial expectations. Encouraged by this success, I turned my attention to further enhancing my instrument's capabilities, particularly in terms of producing distinct and melodious tones when played.

Final attempt at making an instrument 

As a further idea t improve my instrument, so for my final I decided to cut the bamboo chopstick from longest to shorted so the tone is actually controlled by the rubber band.

and for the part that holds the bamboo chopstick, I added grooves at the bottom so the chopstick vibrates with the rubber band making a unique sound when it's played.

the look of the rubber band being played, and the visual effect of waves when the rubber band vibrates are one of the effects that I wanted.

the problem with that is without the chopstick to stretch out the rubber band the sound is too quiet. To get the effect of the wave I made the design shown in the sketch on top.

This is what it looks like when I added chopsticks.

the images show the process of my improving the instrument. the most difficult part for me is to drill grooves at the bottom that is deep enough but not through the box, I had to be really careful, luckily it worked out if it didn't I would have had to add an extra piece of wood on the bottom of the box to keep the chopstick in place.

To elevate the final appearance of my instrument, I decided to infuse it with a flashy and well-crafted aesthetic. With this in mind, I meticulously spray-painted each part using a personally mixed dark blue shade, ensuring a uniform and smooth application. The rich blue colour added sophistication and created a striking contrast against the natural materials. But I didn't stop there; I adorned the instrument's base with carefully selected stickers, strategically placed to enhance its visual appeal. These stickers injected a playful and eye-catching element, adding personality and charm to the overall design. The fusion of the dark blue coating and the decorative stickers resulted in a mesmerizing transformation, turning my instrument into a captivating masterpiece. Not only did it sound remarkable and offer enhanced functionality, but it also boasted a visually captivating appearance, reflecting the perfect blend of technical expertise, creative flair, and attention to detail.

The final look of the instrument

for the musical score, I had to play around with it for quite a long time to make something up because I had no knowledge of music theory, which was a big problem for me to make a short melody. As a solution to that I went to my younger cousin, she knows quite a lot about music theory because she has been playing the violin for a few years now.

After hours of studying I set out to create a short score myself.

This shows the process of my creating the score.

This is the final score.

In this short score composition of mine, I aimed to capture the essence of watching a summer sunset on the beach, accompanied by the gentle caress of the sea breeze. The music unfolds with serene and melodic phrases, creating a sense of tranquillity and peacefulness.
