When you blow harder you increase what comes out of the harmonica, softer to decrease. Frequency can be increased by shifting to the right.

Reactive loads, switching power supplies, phase imbalance. Harmonics are bad for efficient transfer of energy.

See this thread: http://cr4.globalspec.com/thread/51441/Power-system-harmonics

(especially the comment # 2). Some of the links indicated in this comment may not work now but still there are plenty of information in other links.

electrical harmonics, is a property of an AC Electrical System..though it is an unwanted sine wave it cant be rid out...the more reactive loads you will have the greater your harmonics increases...a popular method of decreasing it is through application of capacitor individually or banked or by properly grounding your system.. harmonics than your usual loads..eg. frequency drives...

1. As per IEEE-519, harmonics are the sinusoidal component of periodic wave or frequencies which are integral multiple of fundamental frequency. Ex. A frequency component of 100 hz for 50hz fundamental is called 2 harmonic. Please refer above standard for answer to question.
