Pitch, Scale, Melody, Major and Minor
         Pitch
The highness and lowness of sound is determined by the speed of vibration a moving object makes. The pitch of an instrument or voice is determined by how many times per second it's music making object (reed, string or whatever) vibrates back and forth. The faster the vibration the higher the pitch. The slower the vibration the lower the pitch

 The human ear has a normal hearing range of between 16 and  20,000 vibrations per second. Some high fidelity systems have a range above the ability to hear by the human ear, but the upper harmonic tones enrich the fundamental tones that do lie within the ears range. Animals can hear tones above the normal human range of hearing. Certain dog whistles are pitched in this high area so that they can be heard by a dog but not by a human being

Some high instruments (fast vibrations) are the flute and piccolo. Some low instruments (slow vibrations) are the cello and bassoon. Human voices are categorized as follows:

  • Soprano
  • Alto
  • Tenor
  • Bass

 

         Scale
A collection of pitches available for making music. A scale is a series of pitches from which melodies and harmonies are based. The two most commonly used scales in Western music are called major and minor. Major refers to the greater or larger interval found between the first degree of the major scale, (the tonic), and the scales third degree. Minor refers to the lesser or smaller interval found between the first and third degree of the minor scale. Because of the size and arrangement of the intervals in major or minor scales they have very different characteristics of spirit and mood. Major can be the cheerful or bright scale, where as minor can be serious, sad and sometimes the more romantic scale. But there are many exceptions to this rule. Pieces such as the Largo from Dvorįk “New World Symphony” is a beautiful melancholy melody written with the major scale. The happy melody of Greensleeves is actually written with a minor scale.

 

         Melody
A succession of musical pitches played or sung to a certain rhythm. Melody can also be thought of as the direction and shape of a musical "line" given by a pattern of pitches. Most melodies are derived from scales and melodies  are considered the most expressive element in music, (rhythm the most physical). This is perhaps due to the fact that the first instrument was the human voice and there as many varieties of melodies as there are human emotions.
