In just intonation, the frequencies of the scale notes are related to one another by simple numeric ratios, a common example of this being 1 / 1 , 9 / 8 , 5 / 4 , 4 / 3 , 3 / 2 , 5 / 3 , 15 / 8 , 2 / 1 to define the ratios for the seven notes in a C major scale, plus the return to the ...
In music theory, a major scale and a minor scale that have the same starting note are called parallel keys and are said to be in a parallel relationship. [1] [2] For example, G major and G minor have the same tonic (G) but have different modes, so G minor is the parallel minor of G major.
Though ancient Chinese, Indians, Egyptians and Mesopotamians are known to have studied the mathematical principles of sound, [2] the Pythagoreans (in particular Philolaus and Archytas) [3] of ancient Greece were the first researchers known to have investigated the expression of musical scales in terms of numerical ratios, [4] particularly the ratios of small integers.
See also List of symphonies in C major.) Many masses and settings of the Te Deum in the Classical era were in C major. Mozart and Haydn wrote most of their masses in C major. [3] Gounod (in a review of Sibelius' Third Symphony) said that "only God composes in C major". Six of his own masses are written in C. [4]
"The Pythagorean system would appear to be ideal because of the purity of the fifths, but some consider other intervals, particularly the major third, to be so badly out of tune that major chords [may be considered] a dissonance." [2] The Pythagorean scale is any scale which can be constructed from only pure perfect fifths (3:2) and octaves (2: ...

If a piece of music (or part of a piece of music) is in a major key, then the notes in the corresponding major scale are considered diatonic notes, while the notes outside the major scale are considered chromatic notes. Moreover, the key signature of the piece of music (or section) will generally reflect the accidentals in the corresponding ...
(a) Musical score of a C-major scale. (b) Chromagram obtained from the score. (c) Audio recording of the C-major scale played on a piano. (d) Chromagram obtained from the audio recording. In Western music, the term chroma feature or chromagram closely relates to twelve different pitch classes.
