Music is a rhythmic sound with harmony and a structural pattern. With the development of theoretical and applied science, the conception of music is changes over time. Though, once music was considered only as an art and creativity, but now musician all over the world do not consider music only as an art and creativity.
Rather, music is considered as art and science.
Without a proper implementation of science, music can not turned into its original feature.
Why we can say music is a complex science.
Music is nothing but a study of physics of sound. Physics of music says that music is an applied form of physics. Music is a part of arts else.
The parts of physics that deals with music and composing of music is called musical acoustic or acoustic physics.
Science of musical acoustic physics gives an idea how musical instrument turns sound into nice music. Acoustics physics mainly focusses on the musical instrument and sound physics.
We can not say each sound as music. Each sound will not same interesting to us. A sound of wood chopping may not very interesting to us, even not same pleasure as a music.
You have ever heard about the term tone and tune. Both of two are not same in meaning. But both two are sound in normal sense. In terms of musical context, Tone and tune are different. Tone is not the elements of music. Tone can not create music. But tune can create music. Tone is transform into tune using musical instrument.
Besides of physics role in music, there have psychological and biological impacts on music. Scientists have proves very scientific way different types of music gives pleasure differently with increasing of endorphin level in body.
Music have a mathematical role. Mathematics of music science shows the mathematical role on music.
One of the most common biological role of music is scientifically creating dance. Do you know how music makes a people to dance. Music and dance are interrelated. Different types of musical pattern makes people to dance differently.
