- it is exact and demands exact acoustics. A piece of music is a chart, a graph which indicates frequencies, intensities, volume changes, melody and harmony all at once with the most exact control of time.
- it is rhythmically based on the subdivision of time into fractions which must be done instantaneously, not worked out on paper.
- most of the terms are Italian, German or French and the notation is certainly not English, but a highly developed kind of shorthand that uses symbols to represent ideas. The semantics of music is a universal language.
- music reflects the environment and times of its creation, often even the country and/or racial feelings.
- it requires fantastic coordination of fingers, hands, arms, legs, cheek and facial muscles in addition to control of diaphragmatic, back, stomach and chest muscles which respond to the sound the ear hearts and the mind interprets.
- music takes technically difficult techniques and uses them to create emotions and feelings.
