MUSIC THEORY - Intorduction

Sound
What is sound?
The medium for the transmission of music is sound.
A good understanding of music implies at least a basic understanding of the sounds from nature and how we became aware of it. Sound consist of vibrations of the air (these vibrations are responsible for a human behaviour and suddenly i dont want to jump in to astrology, will write about it later.). It will be very easy to understand the sound if we have a good view of air. Air is a gas, we cant see them cuz the molecules of air are not close to each other as they are solid.
A question pops up in my mind or you might have this doubt. Why don't the molecules in the air just fall down?.


An experipment says that movements of air molecules under a normal room temperature is as fast as a jet travelling at 1,600 KMPH, but we dont feel the collisions with our skin because of extreme lightness of the air molecules.


Now we can imagine why air molecules dont fall down.


The air is actually bouncing off each other so the air pressure is produced. So when a body vibrates, it causes waves of increased and decreased pressure in the air. These waves are the sound.
So we produce sound from vibrating an instrument. In my theory class my honorable Teacher Mr.Chandramohan said that "the sound waves have 4 main attributes which affect the way they are perceived.
1. Amplitude = size of the vibration(loudness)
2. Pitch = Frequency
3. Timber = Spectrum &
4. duration = Lenght"


All these can be sensed by human ear, and sorry i dont know how the human ear works. According to me, its very complicated to understand.


Okay now lets come to Music.


Music- Its a language and languages are invented by the people. There are rules, clean grammer, clarification of spellings and the relationship between words.
People composed music long before it took a written format. Some people still play by ear learning. (thats a good talent) but written music is very useful, the same reason that reading books are useful. Music is easier to study and share if it is written down.


To write music one must be very strong in its theory....


Staff:


The notation are written in Staves. (staff in singular) Stave are 5 parallel lines. the music notes are place on one of the lines or in the space between lines and the vertical bar line divides the staff into short sections called measures or bars. A double bar line used to mark the end of the largeer secion of music and heavy double bar line denotes the end of the piece.












The music of the staff is read from left to right.
