Most anything that gives you a sense of pitch exhibits periodic oscillation, and anything that oscillates periodically will sound pitchy (within certain frequency ranges). The region marked as T in figure 1.2 is the period of oscillation (usually given in seconds), and 1/T is the frequency of the oscillation in cycles per second. So in the case of the “eee” sound, if the period T is measured as 6.6 milliseconds (a millisecond is one 1000th of a second), then the frequency of oscillation will be 1/0.0066 = 150 cycles per second, or 150 Hz (the unit of frequency named after physicist Heinrich Hertz, pronounced...
