Are there 12 notes in an octave?
In the western musical scale, there are 12 notes in every octave. These notes are evenly distributed (geometrically), so the next note above A, which is B flat, has frequency 440 × β where β is the twelfth root of two, or approximately 1.0595. The next note above B flat, which is B, has frequency 440 × β 2.
Why is there 12 notes in an octave?
The idea behind twelve is to build up a collection of notes using just one ratio. The advantage to doing so is that it allows a uniformity that makes modulating between keys possible.

The Austrian-born composer Arnold Schoenberg is credited with the invention of this technique, although other composers (e.g., the American composer Charles Ives and the Austrian Josef Hauer) anticipated Schoenberg’s invention by writing music that in a few respects was similar technically to his 12-tone music.
Why is it called octave?
The word “octave” comes from a Latin root meaning “eight”. It seems an odd name for a frequency that is two times, not eight times, higher. The octave was named by musicians who were more interested in how octaves are divided into scales, than in how their frequencies are related.
How many tones is 1 octave?
The octave An octave is thus formed by 5 tones and 2 diatonic semitones (see Figure 1 at the beginning of the course). Since a tone itself consists of a chromatic semitone and a diatonic semitone, the octave is thus formed of 12 semitones, of which 5 chromatic semitones and 7 diatonic semitones.
