The ancient Greek meaning of enharmonic is that the scale contains at least one very narrow interval. (The spacing of each pair notes between their bracketing fixed notes is usually either approximately or exactly the same, so when there is one narrow interval in one bracket there is almost always another one inside the other bracket.) [4] Modern musical vocabulary has re-used the word ...
A musical passage notated as flats. The same passage notated as sharps, requiring fewer canceling natural signs. Sets of notes that involve pitch relationships — scales, key signatures, or intervals, [1] for example — can also be referred to as enharmonic (e.g., the keys of C ♯ major and D ♭ major contain identical pitches and are therefore enharmonic).
Another way to express this is that the just fifth has a frequency ratio (compared to the tonic) of 3:2 or 1.5 to 1, whereas the seventh semitone (based on 12 equal logarithmic divisions of an octave) is the seventh power of the twelfth root of two or 1.4983... to 1, which is not quite the same (a difference of about 0.1%). Take the just fifth ...
The double harmonic major scale [1] is a musical scale with a flattened second and sixth degree. This scale is enharmonic to the Mayamalavagowla raga, Bhairav raga, Byzantine scale, Arabic scale (Hijaz Kar), [1] [2] and Gypsy major scale. [3] It can be likened to a gypsy scale because of the diminished step between the 1st and 2nd degrees.
C-sharp major, the enharmonic equivalent to D-flat major, has seven sharps, whereas D-flat major only has five flats; thus D-flat major is often used as the parallel major for C-sharp minor. (The same enharmonic situation occurs with the keys of A-flat major and G-sharp minor, and to some extent, with the keys of G-flat major and F-sharp minor).
[2] The Pythagorean scale is any scale which can be constructed from only pure perfect fifths (3:2) and octaves (2:1). [5] In Greek music it was used to tune tetrachords, which were composed into scales spanning an octave. [6] A distinction can be made between extended Pythagorean tuning and a 12-tone Pythagorean temperament.
Diminished seventh chords may also be rooted on scale degrees other than the leading-tone, either as secondary function chords temporarily borrowed from other keys, or as appoggiatura chords: a chord rooted on the raised second scale degree (D ♯ –F ♯ –A–C in the key of C) acts as an appoggiatura to the tonic (C major) chord, and one ...
Augmented fifth on C. In Western classical music, an augmented fifth (Play ⓘ) is an interval produced by widening a perfect fifth by a chromatic semitone. [1] [3] For instance, the interval from C to G is a perfect fifth, seven semitones wide, and both the intervals from C ♭ to G, and from C to G ♯ are augmented fifths, spanning eight semitones.
