In acoustical analysis, a one-third octave band is defined as a frequency band whose upper band-edge frequency ( f 2 or f max ) is the lower band frequency ( f 1 or f min ) times the tenth root of ten, [4] or 1.2589 : The first of the one-third octave bands ends at a frequency 125.9% higher than the starting frequency for all of them, the base ...
A graph of the A-, B-, C- and D-weightings across the frequency range 10 Hz – 20 kHz Video illustrating A-weighting by analyzing a sine sweep (contains audio). A-weighting is a form of frequency weighting and the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level.

Thus the major third is considered not a third but a ditone, literally "two tones", and is (9:8) 2 = 81:64, rather than the independent and harmonic just 5:4 = 80:64 directly below. A whole tone is a secondary interval, being derived from two perfect fifths minus an octave, (3:2) 2 /2 = 9:8.
The Orff Approach of music education uses very rudimentary forms of everyday activity for the purpose of music creation by music students. The Orff Approach is a "child-centered way of learning" music education that treats music as a basic system like language and believes that just as every child can learn language without formal instruction so can every child learn music by a gentle and ...
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]
The principle of analysis has been variously criticized, especially by composers, such as Edgard Varèse's claim that, "to explain by means of [analysis] is to decompose, to mutilate the spirit of a work". [73] Schenkerian analysis is a method of musical analysis of tonal music based on the theories of Heinrich Schenker (1868–1935). The goal ...
These partials are customarily given names such as hum, prime, minor third (or tierce), fifth (or quint), octave (or nominal), upper octave, etc. The strike note of the bell, which is determined by three partials (the octave, upper fifth, and the upper octave), is generally close to the pitch of the prime in a well-tuned bell."
Analysis is an activity most often engaged in by musicologists and most often applied to western classical music, although music of non-western cultures and of unnotated oral traditions is also often analysed. An analysis can be conducted on a single piece of music, on a portion or element of a piece or on a collection of pieces.
