In music theory, the term mode or modus is used in a number of distinct senses, depending on context.
In music theory, the minor scale is three scale patterns – the natural minor scale, the harmonic minor scale, and the melodic minor scale – mirroring the major scale, with its harmonic and melodic forms
In music theory, a scale is any set of musical notes ordered by fundamental frequency or pitch. A scale ordered by increasing pitch is an ascending scale, and a scale ordered by decreasing pitch is a descending scale.
In music theory, an interval is a difference in pitch between two sounds. 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.
A jazz scale is any musical scale used in jazz. Many "jazz scales" are common scales drawn from Western European classical music, including the diatonic, whole-tone, octatonic, and the modes of the ascending melodic minor. All of these scales were commonly used by late nineteenth and early twentieth-century composers such as Rimsky-Korsakov, Debussy, Ravel and Stravinsky, often in ways that directly anticipate jazz practice. Some jazz scales, such as the bebop scales, add additional chromatic passing tones to the familiar diatonic scales.
In music, modulation is the change from one tonality to another. This may or may not be accompanied by a change in key signature. Modulations articulate or create the structure or form of many pieces, as well as add interest. Treatment of a chord as the tonic for less than a phrase is considered tonicization.
Modulation is the essential part of the art. Without it there is little music, for a piece derives its true beauty not from the large number of fixed modes which it embraces but rather from the subtle fabric of its modulation.
A semitone, also called a half step or a half tone, is the smallest musical interval commonly used in Western tonal music, and it is considered the most dissonant when sounded harmonically. It is defined as the interval between two adjacent notes in a 12-tone scale. For example, C is adjacent to C♯; the interval between them is a semitone.
In music theory, an augmented sixth chord contains the interval of an augmented sixth, usually above its bass tone. This chord has its origins in the Renaissance, was further developed in the Baroque, and became a distinctive part of the musical style of the Classical and Romantic periods.
Chromaticism is a compositional technique interspersing the primary diatonic pitches and chords with other pitches of the chromatic scale. In simple terms, within each octave, diatonic music uses only seven different notes, rather than the twelve available on a standard piano keyboard. Music is chromatic when it uses more than just these seven notes.
A quarter tone is a pitch halfway between the usual notes of a chromatic scale or an interval about half as wide as a semitone, which itself is half a whole tone. Quarter tones divide the octave by 50 cents each, and have 24 different pitches.
In music, the Phrygian dominant scale is the fifth mode of the harmonic minor scale, the fifth being the dominant. Also called the altered Phrygian scale, dominant flat 2 flat 6, or Freygish scale. It resembles the Phrygian mode but with a major third, rather than a minor third.
In Western music, the adjectives major and minor may describe an interval, chord, scale, or key. A composition, movement, section, or phrase may also be referred to by its key, including whether that key is major or minor.
In music theory, the harmonic major scale is a musical scale found in some music from the common practice era and now used occasionally, most often in jazz. In George Russell's Lydian Chromatic Concept it is the fifth mode (V) of the Lydian Diminished scale. It corresponds to the Raga Sarasangi in Indian Carnatic music.
The double harmonic major scale is a musical scale with a flattened second and sixth degree. This is also known as Mayamalavagowla, Bhairav Raga, Byzantine scale, Arabic, and Gypsy major. It can be likened to a gypsy scale because of the diminished step between the 1st and 2nd degrees. Arabic scale may also refer to any Arabic mode, the simplest of which, however, to Westerners, resembles the double harmonic major scale.
The Hungarian minor scale, double harmonic minor scale, or Gypsy minor scale is a type of combined musical scale. It is the fourth mode of the double harmonic scale. It is the same as the harmonic minor scale, except that it has a raised fourth scale degree to introduce an additional gap, or augmented second. It is a symmetrical scale with a slightly ambiguous tonal centre, due to the many half steps.
The Algerian Scale is a scale frequently used in Algerian, Berber, and North African music. The frequent use of 1.5 steps in the scale contributes to a sound commonly associated with Moorish music.
In music, the major Neapolitan scale and the minor Neapolitan scale are two musical scales. Both scales are minor, in that they both contain the note a minor third above the root. The major and minor Neapolitan scales are instead differentiated by the quality of their sixth.
In music, the Romanian minor scale or Ukrainian Dorian scale or altered Dorian scale is a musical scale or the fourth mode of the harmonic minor scale. It is "similar to the dorian mode, but with a tritone and variable sixth and seventh degrees". It is related to both the Freygish and Misheberak scales and is used in Jewish music, "predominant in klezmer bulgarish and doina (doyne)." "When the Ukrainian Dorian scale functions in the synagogue, it is a mode known as the Mi sheberach or Av horachamon. Arab and Greek scholars give other names to the scale: Nikriz (نكريز) and Aulos, respectively."
The jazz minor scale or ascending melodic minor scale is a derivative of the melodic minor scale, except only the ascending form of the scale is used. As the name implies, it is primarily used in jazz. It may be derived from the major scale with a minor third, making it a synthetic scale, and features a dominant seventh chord on the fifth degree (V) like the harmonic minor scale. It can also be derived from the diatonic Dorian mode with a major seventh.
The Hungarian major scale is an ancohemitonic, heptatonic scale with the following interval structure in semitones: 3, 1, 2, 1, 2, 1, 2, giving it the notes C D♯ E F♯ G A B♭ in the key of C. As such the scale is a subset of the octatonic scale, alternating semitones and whole tones. It is, "used extensively in Hungarian gypsy music [sic]," as well as in classical music by composers including Franz Liszt and Zoltán Kodály ," as well as in Thea Musgrave's Horn Concerto (1971). As a chord scale, Hungarian Major is both a dominant and a diminished scale, with a fully diminished seventh chord composed of C, D#, F#, and A, and a dominant seventh chord composed of C, E, G, and Bb. This is an enharmonic mode of Bb Harmonic Major, along with G Harmonic Minor and E Hungarian Minor. The root note of D Aeolian Dominant is raised a semitone to D#, and the root note of B Phrygian Dominant lowered a semitone to Bb. There is also a ♮6 & ♮2 with the Bb Super Lydian Augmented scale, lowering the C# & G# to C♮ & G♮.
