Basic property of sound: Timbre - Pitch - Duration - Intensity
Music has a total Seven basic tones or notes as: C D E F G A B --------- These tones or notes are all Unaltered - Which mean there is No Accidentals apply to the tones or notes "Sharp or Flat".
Beside these seven basic unaltered tones or notes. There are Five Pairs of tones or notes which use accidentals such as Sharp or Flat.
When you apply accidental "s" for example: a sharp to an unaltered tone or note, it will increase "Raise" the pitch of the tone or note by an Half-step.
But when you appy a flat to an unaltered tone or note, it will decrease "lower" the pitch of a tone or note by an Half-step. There are some rules which you must accept such as:
There is an Half step between B & C and between E & F. Other wise there is a Whole-step between others.
Time and Sound are the Basic material of Music.
We are going to learn the properties of Sound, and be introduced to some of the basic terminology used to the study of Sound.
Sound is generated by vibration of a body such as a guitar string or any objects can be made to vibrate will produce sound.
Sound is transmitted to our ears by vibrational disturbance called Sound Wave.
Sounds impress us as being relatively "High or Low". This is called Pitch. One of property of Sound.
The pitch of the sound is determined by the Frequency of the vibration of the sound source.
Pitch is a technical term which express the "Highness or Lowness" of a sound. So we can say this: Frequency of a vibration of any object determine the Pitch of a sound.
The Faster the vibrating body is caused to vibrated, the Higher the Pitch. Vice versa, the Slower the vibrating body is caused, the Lower the Pitch.
High and Low are subjective description of the Pitch or Frequency of a sound.
The Loudness and Softness of a sound is called Intensity.
Sound waves not only transmitted Pitch, but it also transmit Intensity to our's ears.
Intensity is determined by the amount of Energy transmitted from the source to the ears, this is measured by term called "Amplitude".
Amplitude is a measurement of Intensity.
Our's ears can distinguishing the difference in Pitch - Intensity, but also distinguish the difference in the Quality of sound, which is called "Timbre".
So property of sound which enable us to tell the difference between difference instruments is called Timbre. For example you can tell if it is a piano or guitar sounds.
Timbre, Pitch, Intensity are trnasmitted to the ears through Sound-Waves. Since Time & Sound are the Basic materials of Music. The four property of sound is called Duration.
The term Ryhthm id applied to all aspects of time in music including Duration. Music utilize sounds ranging from very Short to very Long.
All aspects of Duration are part of the Basic element of music called Rhythm. Rhythm is a primary matter of Time.
Amplitude is a measurement of Intensity.
