Music Math: Playing Notes with Equations
Music and math have a lot in common. In this project, you will explore the mathematical relation between music notes and equations to create beautiful music. You will use a monochord, a single string with one fixed bridge and a movable fret, to measure the frequency of the notes. You will then use mathematical equations to calculate the length of the string for each note.
The hypothesis is that different lengths of a 60cm string, where the fret is placed, will produce speculated notes and will fit in a mathematical equation.
Method & Materials
You will use a monochord, a single string with one fixed bridge and a movable fret, to measure the frequency of the notes. You will then use mathematical equations to calculate the length of the string for each note.
You will need a monochord, a single string with one fixed bridge and a movable fret, a CBL, a microphone, a calculator, the program SOUND and FREQ, and an intellitouch tuner.
The results of this project showed that music and math have a lot in common. It was found that the string length for each note, in any given octave, fits in a geometric sequence. It was also found that two notes that are one octave apart, the string lengths are in a ratio of 1:1/2. The note sol, in all the octaves is 2/3 of the length of the string.
Why do this project?
This science project is interesting and unique because it shows the mathematical relation between music notes and equations.
Experiment variations to consider include using different musical instruments and exploring different mathematical equations.
