xylophone. Reading up and researching the xylophone I found that like other instruments you have to be careful building for it is simple mistakes that can ruin the melody. I found that in building a xylophone all of the keys are different sizes and each one plays a different note, this is somethingI thought to be very helpful for someone that doesn't play an instrument. I also found that it can be built from various materials, including wood, plastic bottles with different amounts of water and metal, this also made it easier to get the supplies. I also found that this instrument can play majority of the major notes needed to perform our song.
