A heptatonic scale is a musical scale that has seven pitches, or tones, per octave. Examples include: the diatonic scale; including the major scale and its modes (notably the natural minor scale, or Aeolian mode) the melodic minor scale, like the Aeolian mode but with raised 6th and 7th ascending. the harmonic minor scale, like the Aeolian mode ...
Diatonic scale. In music theory, a diatonic scale is any heptatonic 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, depending on their position in the scale. This pattern ensures that, in a diatonic ...
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]
The same community that may use one set of instruments tuned to a certain scale (i.e. pentatonic), can use a different scale for a different set of instruments, or song type (i.e. heptatonic). [2] [3] [4] In traditional African music, scales are practised and thought of as descending from top to bottom.
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.
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 ...
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 white-note major and minor pentatonic scales. Two pentatonic scales common to jazz are the major pentatonic scale and the minor pentatonic scale. They are both modes of one another. The major pentatonic scale begins with a major scale and omits the fourth and the seventh scale degrees.
