MINI HARPSlide2
Objective:
Our objective is to investigate how the concepts of wave and sound are applied in the making of one octave musical instrument
.Hypothesis: We hypothesize that the diameter, the thickness and the length of the strings can affect the musical fraction.
INTRODUCTIONSlide3
Variables:
Independent: The length of the strings.
Dependent: The range of sounds different length of every each strings produce.Controlled: The material of string, length of string, thickness of stringINTRODUCTIONSlide4
Wood
Nylon Badminton stringGlueRulerPen / Pencil Scissor
Plastic
MaterialsSlide5
Find the good wood
that strong enoughCut it into 12 pieces Connect all the wood so they became into one harp. (There are three harps)Collect 3 different strings (nylon, plastic, badminton’s racket string)
The processSlide6
Make 8 holes for each harp
Put the string one by one to the hole, each hole has one string
The harps will produce sound if we strum the harpsTo test whether each harp produces the right sound, we should listen it carefully.THE PROCESSSlide7
So the conclusion is the harp that contain of nylon string with the thickness diameter is more loudness that the other strings. The plastic strings is also more loudness than the badminton strings.
