MUSIC: What note is one octave higher than a “C” note?

Is high C the name of note?
@Iwillwait

@GhostNuclear C5

@Iwillwait Except that is a note, not an octave.

@JamesBugman




There is actually an international standard here: called International Pitch Notation (IPN), it labels Middle C as C4. An octave above Middle C is C5, an octave below Middle C is C3, etc.

@Iwillwait Ooo.. right, thanks for clarifying. You are correct of course.

@Iwillwait this is correct

@Iwillwait You are assuming a particular starting C; I don't "see" that in the question.
