Frequency or pitch
- *Pitch is a musical term with a meaning which is very close to the
meaning of the scientific term frequency*
- *The scientific term frequency is slightly more specific than the
normal use of the word frequency, which means simply "how often something
happens".*
- *It means the number of times an event occurs in a period of time.*
- *Hertz (abbreviated to Hz), is the scientific unit for the number of
times an event happens in one second.*
- *For example, an electric current which alternates its direction 50
times each second is referred to as 50Hz*
- *A computer with a clock tick 90 million times a second is called a
90MHz machine ("M" being short for the prefix "Mega" meaning a million)*
- *H. R. Hertz was a physicist in the 19th Century (1857-1894)*
- *A note (in my definition) has one, and only one, pitch.*
- *The pitch or frequency can be stated in a number of different ways:*
- *The scientific way, e.g. "512Hz".*
*This method is absolutely precise and accurate*
*There is no possibility of error or inaccuracy*
**
- As a musical description, e.g. "Treble C" or, " c' ", or "The third
space on the treble-clef", or "C above middle C"
*This method is not precise and not accurate*
*There is scope for misunderstanding*
*If the instruction is understood, the exact pitch is imprecise and will
depend on the tuning of the instrument*
