Frequency and Pitch
Frequency if the measure of how many cycles a wave complete per second.
Frequency (f) is measures in Hertz
Period (T) in the inverse of infrequency is is measured in seconds
Frequency = Cycles/Second Perdiod = Seconds/Cycle
f = 1/T T = 1/f
The perception is frequency is know as pitch.
Intervals
An octave is doubling of the frequency.
ie 440 Hz is an A
the next A after 440 Hz is 880 Hz
In westen music the octave is divided into 12 semi-tones
