modulation
n 1: a musical passage moving from one key to another [synonym:
{transition}, {modulation}]
2: (electronics) the transmission of a signal by using it to
vary a carrier wave; changing the carrier's amplitude or
frequency or phase
3: rise and fall of the voice pitch [synonym: {intonation},
{modulation}, {pitch contour}]
4: a manner of speaking in which the loudness or pitch or tone
of the voice is modified [synonym: {modulation}, {inflection}]

Modulation \Mod`u*la"tion\, n. [L. modulatio: cf. F.
modulation.]
1. The act of modulating, or the state of being modulated;
as, the modulation of the voice.
[1913 Webster]

2. Sound modulated; melody. [R.] --Thomson.
[1913 Webster]

3. (Mus.) A change of key, whether transient, or until the
music becomes established in the new key; a shifting of
the tonality of a piece, so that the harmonies all center
upon a new keynote or tonic; the art of transition out of
the original key into one nearly related, and so on, it
may be, by successive changes, into a key quite remote.
There are also sudden and unprepared modulations.
[1913 Webster]

4. (Electronics) The alteration of hte amplitude, intensity,
frequency, or phase (of the carrier wave of a radio
signal) at intervals, so as to represent information to be
transmitted.
[WordNet 1.5]
