A heptatonic scale is a musical scale that has seven pitches, or tones, per octave. Examples include: Examples include: the diatonic scale ; including the major scale and its modes (notably the natural minor scale, or Aeolian mode)
In music theory a diatonic scale is a heptatonic (seven-note) scale that includes five whole steps (whole tones) and two half steps (semitones) in each octave, in which the two half steps are separated from each other by either two or three whole steps. In other words, the half steps are maximally separated from each other.
Melodies can be based on a diatonic scale and maintain its tonal characteristics but contain many accidentals, up to all twelve tones of the chromatic scale, such as the opening of Henry Purcell's "Thy Hand, Belinda" from Dido and Aeneas (1689) with figured bass), which features eleven of twelve pitches while chromatically descending by half steps, [1] the missing pitch being sung later.
The scale degrees of a heptatonic (7-note) scale can also be named using the terms tonic, supertonic, mediant, subdominant, dominant, submediant, subtonic. If the subtonic is a semitone away from the tonic, then it is usually called the leading-tone (or leading-note); otherwise the leading-tone refers to the raised subtonic.
One heptatonic, or seven-note, conception of the blues scale is as a diatonic scale (a major scale) with lowered third, fifth, and seventh degrees, [9] which is equivalent to the dorian ♭ 5 scale, the second mode of the harmonic major scale. Blues practice is derived from the "conjunction of 'African scales' and the diatonic western scales". [10]
For the ordinary diatonic scales described here, the T-s are tones and the s-s are semitones which are half, or approximately half the size of the tone.But in the more general regular diatonic tunings, the two steps can be of any relation within the range between T = 171.43 ¢ (for s = T at the high extreme) and T = 240 ¢ (for s = 0 at the low extreme) in musical cents (fifth, p5, between 685 ...
A variety of musical scales are used in traditional Japanese music. While the Chinese Shí-èr-lǜ has influenced Japanese music since the Heian period, in practice Japanese traditional music is often based on pentatonic (five tone) or heptatonic (seven tone) scales. [1] In some instances, harmonic minor is used, while the melodic minor is ...
English: Comparison of the intervals in the most commonly used moment of symmetry (MOS) scales (diatonic scale vs pentatonic scale) plotted on chromatic circle diagrams. Either MOS scale has intervals of two sizes each but they are different. Notably, the pentatonic scale omits the semitones above and below the tonic, as well as the tritone.
