An octave is the interval between one musical pitch and another with double or half its frequency.For example, if one note has a frequency of 440 Hz, the note one octave above is at 880 Hz, and the note one octave below is at 220 Hz.
D [1] is a musical note a whole tone above C, and is known as Re within the fixed-Do solfege system. Its enharmonic equivalents are C (C-double sharp) and E (E-double flat). It is the third semitone of the solfège. When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of middle D (D 4) is ...

Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
Higher octaves use successively higher number and lower octaves use successively lower numbers. The lowest note on most pianos is A 0 , the highest is C 8 . For instance, the standard 440 Hz tuning pitch is named A 4 in scientific notation and instead named a′ in Helmholtz notation.
For example, the frequency one octave above 40 Hz is 80 Hz. The term is derived from the Western musical scale where an octave is a doubling in frequency. [note 1] Specification in terms of octaves is therefore common in audio electronics. Along with the decade, it is a unit used to describe frequency bands or frequency ratios. [1] [2]
A jump from the lowest semitone to the highest semitone in one octave doubles the frequency (for example, the fifth A is 440 Hz and the sixth A is 880 Hz). The frequency of a pitch is derived by multiplying (ascending) or dividing (descending) the frequency of the previous pitch by the twelfth root of two (approximately 1.059463).
For instance, three pure major thirds stack up to 125 / 64 , which at 1 159 cents is nearly a quarter tone away from the octave (1200 cents). So there is no way to have both the octave and the major third in just intonation for all the intervals in the same twelve-tone system.
