In a 12-note approximately equally divided scale, any interval can be defined in terms of an appropriate number of semitones (e.g. a whole tone or major second is 2 semitones wide, a major third 4 semitones, and a perfect fifth 7 semitones). In music theory, a distinction is made [7] between a diatonic semitone, or minor second (an interval ...
In music theory, an interval is a difference in pitch between two sounds. [1] An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord.
Sacred harp music uses a different kind of scale and theory in practice. The music focuses on the solfege "fa, sol, la" on the music scale. Sacred Harp also employs a different notation involving "shape notes", or notes that are shaped to correspond to a certain solfege syllable on the music scale.
Minor tone (10:9) Play ⓘ. In Western music theory, a major second (sometimes also called whole tone or a whole step) is a second spanning two semitones (Play ⓘ).A second is a musical interval encompassing two adjacent staff positions (see Interval number for more details).
In standard Western classical music practice, all tone clusters are classifiable as secundal chords—that is, they are constructed from minor seconds (intervals of one semitone), major seconds (intervals of two semitones), or, in the case of certain pentatonic clusters, augmented seconds (intervals of three semitones).
In music theory, an eleventh is a compound interval consisting of an octave plus a fourth. A perfect eleventh spans 17 and the augmented eleventh 18 semitones, or 10 steps in a diatonic scale. Since there are only seven degrees in a diatonic scale, the eleventh degree is the same as the subdominant (IV). [1]
Diatonic and chromatic are terms in music theory that are used to characterize scales. The terms are also applied to musical instruments, intervals, chords, notes, musical styles, and kinds of harmony. They are very often used as a pair, especially when applied to contrasting features of the common practice music of the period 1600–1900. [a]
In classical music from Western culture, a diminished third (Play ⓘ) is the musical interval produced by narrowing a minor third by a chromatic semitone. [ 1 ] [ 4 ] For instance, the interval from A to C is a minor third, three semitones wide, and both the intervals from A ♯ to C, and from A to C ♭ are diminished thirds, two semitones wide.
