_Harmony_ is simultaneous; _melody_ is successive; _harmony_ is the pleasing correspondence of two or more notes sounded at once, _melody_ the pleasing succession of a number of notes continuously following one another. A _melody_ may be wholly in one part; _harmony_ must be of two or more parts. Accordant notes of different pitch sounded simultaneously produce _harmony_; _unison_ is the simultaneous sounding of two or more notes of the same pitch. When the pitch is the same, there may be _unison_ between sounds of very different volume and quality, as a voice and a bell may sound in _unison_. Tones sounded at the interval of an octave are also said to be in _unison_, altho this is not literally exact; this usage arises from the fact that bass and tenor voices in attempting to sound the same note as the soprano and alto will in fact sound a note an octave below. _Music_ may denote the simplest _melody_ or the most complex and perfect _harmony_. A _symphony_ (apart from its technical orchestral sense) is any pleasing consonance of musical sounds, vocal or instrumental, as of many accordant voices or instruments.

_Memory_ is the faculty by which knowledge is retained or recalled; in a more general sense, _memory_ is a retention of knowledge within the grasp of the mind, while _remembrance_ is the having what is known consciously before the mind. _Remembrance_ may be voluntary or involuntary; a thing is brought to _remembrance_ or we call it to _remembrance_; the same is true of _memory_. _Recollection_ involves volition, the mind making a distinct effort to recall something, or fixing the attention actively upon it when recalled. _Reminiscence_ is a half-dreamy _memory_ of scenes or events long past; _retrospection_ is a distinct turning of the mind back upon the past, bringing long periods under survey. _Retrospection_ is to _reminiscence_ much what _recollection_ is to _remembrance_.
