In the standard equal-tempered scale in use in nearly all modern Western music, each octave is divided into 12 semitone intervals, where each semitone interval is taken to represent a fixed percentage increase in frequency.An increase in pitch of one octave corresponds to a doubling in frequency (ignoring some subtle psychoacoustic effects near the limits of perception). If we say that each semitone corresponds to an increase of a factor k in frequency, then from the fact that twelve semitones equal one octave we obtain:k12 = 2.Hence, k = 21/12 which is approximately 1.05946. That is, an increase in pitch of one semitone is equivalent to an increase in frequency of about 5.946%.
Octave Maus was born in 1856.
It is someone who's vocal range can cover a range of octaves, I think it is usually at least 2... Hope this helps :)
Perfect Fifth. In a D Major Scale, the tones are D E F# G A B C# D so if you count up from D with D as number one the fifth tone is the A. In this case you could also refer to it as a Major Fifth.
It's when between to notes, them included, of a scale, you can count 8 notes. Example: - on C major C1 and C2 (or any other Cn and Cn+1) have an interval of an eighht - also called an octave. C D E F G A B C 1 2 3 4 5 6 7 8 - on E major E F# G# A B C# D# E 1 2 3 4 5 6 7 8

An interval of eight notes is known as an octave.
octave is the name of a particular interval size
An octave is not a fifth. A fifth is any interval of exactly 7 half-steps. An octave is any interval of exactly 12 half-steps.

perfect fourth
Within an octave there are four perfect intervals: perfect unison (P1), perfect fourth (P4), perfect fifth (P5), and perfect octave (P8).
