A science project on the difference between noise and music is about the science of psychology more than it is about the science of acoustics. You will need to collect information about what kinds of sounds are considered noise and what kind of sounds are considered music. One way to approach this is to look at how different people perceive the elements of music -- things such as tone, scale and chords. A short bibliography of the participants can be correlated with the choices. Suggested points in the short biography are: age, gender, educational level, music style preference, ability to play an instrument and having resided in a foreign country. You can change these data parameters until you get clear results.
Play tones from different sources -- musical instruments, animal sounds, objects breaking and so on -- and ask people to judge them as "noise" or "music." If you have access to a synthesiser, use sampled sounds for the first test, then play a scale of melody with the sampled sounds and ask for an evaluation of these. Your basic hypothesis for the project is that the difference between noise and music is subjective. To show this on tone tests, you need to find a set of tones that approximately half of the participants think is noise, and the other half considers to be musical.
Songs don't usually use all the possible notes that are available. Most songs use only a carefully selected subset of the available notes. The notes selected often evoke types of music when played in sequence. Have people assign a name to scales such as Major, Minor, Phrygian, Blues, Bhairavi and Pentatonic. Most people will identify these as happy or normal, sad or Gypsy, Spanish or Flamenco, Blues or Jazz, Indian and Chinese. Do not suggest these classifications -- let participants choose a single word and try to relate choices to biographies. The fact that an ascending or descending sequence of notes can suggest a mood or culture shows how subjective music is.
A chord consists of several notes played together. Before the Twentieth century, most people thought any chord with more than three notes was "wrong" or "discordant." Even today, four-note chords are more acceptable in Jazz and Classical music than in more popular musical forms. Ask people to describe played chords. Include simple Major and Minor chords, traditional four-note chords such as the sixth chord, the dominant seven chord and the Major seven chord. Also include chords that most people find discordant -- such as chords that include the second or flattened fifth.
