I will build, and then later on play the Flute for my group presentation. Our objective is to build an instrument, and then play it for our class. There are obstacles that we need to do such as calculation and such in order to do this. I researched the background of the Flute. To play the flute and produce sound, someone will have to blow through a hole at the end of the Flute and while blowing, there would be holes at the other end of the Flute where the persons fingers will be covering the holes and uncovering the holes based on what notes that they want to play, and to change the notes. The Flute is a basic pipe; it can have either one fixed end or two loose ends. It also has holes that are different lengths from the hole at the opposite end, which is where the person blows into.  When  i think about myself playing the Flute in order to change the sound, i will have to simply practice where at what time my fingers cover and uncover certain notes (the holes at the opposite end of the blow in hole).  Compared to waves,  the size of the flute, and where the holes are, determines the sound outcome. As the notes changes, the notes change as well

Energy from the air molecules transfer into the hole that is blown through, and they vibrate within the Flute, and as that happen, having the notes at the other end of the Flute either covered or uncovered, the Flute vibrations actually turns into sound. In order to change the pitch, the notes that are on the Flute are the holes. The hole that is farthest away from where it is to be blown into is the lowest note.  The hole closest to where we have to blow in the holes to produce sound makes the highest pitch. So to change the pitch, simply change the notes. I will just use my fingers in order to play this instrument. I will play my instrument based off of the songs notes.  If a note indicated that have to play note A, then ill have to use one of my fingers to cover up the A note. To build this instrument, I will have to have a PVC pipe for the flute structure itself, duck tape to have a fixed end flute by covering one side of the pipe, and a drill to drill holes where the notes will be.
