'''''Pitch Shifting'' alters the pitch of your playing.'''
There are two basic kinds: '''chromatic''' (or stepwise) and '''harmony''' (or ''intelligent'', or sometimes called a ''harmonizer''). '''Chromatic simply shifts the pitch by some set amount''', usually specified in terms of a chromatic interval (m2, M2, m3, M3, etc.), but often also allowing a continuous range of values in between the intervals.
'''A Harmony (or ''Intelligent'') pitch shifter shifts the frequency by an interval of an ''unspecified'' quality (2nd, 3rd, 4th, etc.). It detects the pitch of the note being played and uses the corresponding interval in the scale selected'''. For instance, if you use the scale of C Major with a shift of a 3rd and play a C note, the shifter would output an E, a M3 above C. However, if you played an A, it would output a C which is only a m3 above A. Advanced intelligent shifters allow various scales beyond all the Major and Natural Minor scales, such as Harmonic Minor (and some even allow you to program your own custom scales, including using tunings outside of equal temperament).
