perfect pitch/relative pitch

Does anyone know what Perfect pitch and Relative pitch is?

here you go, I did a search on it

The ability to identify any pitch heard or produce any pitch referred to by name.
Absolute pitch, or perfect pitch, is "the ability to attach labels to isolated auditory stimuli on the basis of pitch alone" without external reference.[1] Possessors of absolute pitch exhibit the ability in varying degrees. Generally, absolute pitch implies some or all of the following abilities:

Identify and name individual pitches played on various instruments
Name the key of a given piece of tonal music
Identify and name all the tones of a given chord or other tonal mass
Sing a given pitch without an external reference
Name the pitches of common everyday occurrences such as car horns
Individuals may possess both absolute pitch and relative pitch ability in varying degrees. Both relative and absolute pitch work together in actual musical listening and practice, although individuals exhibit preferred strategies in using each skill.[2]


The ability to recognize or produce a tone by mentally establishing a relationship between its pitch and that of a recently heard tone.
The term relative pitch may denote:

the distance of a musical note from a set point of reference, e.g. "three octaves above middle C"
a musician's ability to identify the intervals between given tones, regardless of their relation to concert pitch (A = 440 Hz)
the skill used by singers to correctly sing a melody, following musical notation, by pitching each note in the melody according to its distance from the previous note. Alternatively, the same skill which allows someone to hear a melody for the first time and name the notes relative to some known starting pitch.

Ok i think i understand. So perfect pitch is the ability to recognize any note and relative pitch is the ability to find a note from hearing a previos note? I have some of these abilities  , mostly relative pitch.
So whats concert pitch? i remember hearing that in my band class, i never got an explanaition of what it is (its strange that each instument had a different note name for a certain concert pitch), all i know is its the same pitch as a piano.

the pitch used to tune instruments for concert performances

I think perfect pitch is more than just note-naming.  There are many components, which are present in varying degrees in people with perfect pitch:
-identify 1 note, period. ("C" for example.)*
-identify 1 note in context.
-know if something's out of tune, period.
-know if something's out of tune in context
-identify 1 note at a time (includes any of the 12 possible notes).
-identify 1 note at a time in context.
-identify all notes in a small chord.
-identify key of a passage. *
-identify key of a whole piece.
-sing 1 note when told to, period. ("C" for example.)
-sing any note when told to. (known as active AP)
-identifying notes in a large chord.
-identify all notes in small chord in context
-being able to say how in tune something is, period
-being able to say how in tune something is in context.
-transcription (involves identifying notes in large chords in context)

I'm not saying anyone with AP can do all of these, but at least they can do the starred ones.  If they can only do those, though, their AP would be quite limited.
