A tetratonic scale is a musical scale or mode with four notes per octave. This is in contrast to a heptatonic (seven-note) scale such as the major scale and minor scale, or a dodecatonic (chromatic 12-note) scale, both common in modern Western music. Tetratonic scales are not common in modern art music, and are generally associated with prehistoric music. [2] [3]
Tetratonic scales were common among the Plains Indians, though less common than the pentatonic scale. [4] Amongst the Arapaho, Blackfoot, Crow, Omaha, Kiowa, Pawnee, and Sioux, as well as some Plateau tribes, especially the Flathead, the tetratonic and pentatonic scales used are anhemitonic (that is, they do not include semitones). [5] Tetratonic scales have also been noted among the music of the Creek Indians, [6] and in the Great Basin region among the Washo, Ute, Paiute, and Shoshone. [7] In the Southwest, the Navajo people also largely used the pentatonic and tetratonic, occasionally also tritonic scales. [8]
Tetratonic music was known among the Inuit, including the Greenlandic peoples. [9]
A 1969 study by ethnomusicologist Mervyn McLean noted that tetratonic scales were the second-most common type among the Maori tribes surveyed, accounting for 31% of scales used. The most common were tritonic (3-note) scales at 47%, while the third-most was ditonic (two-note) scales at 17%. [10]
Tetratonic music was noted as common in Polynesia and Melanesia. [11] On Guadalcanal in particular, anhemitonic pentatonic and tetratonic scales are the predominant types, although the minor second does nevertheless occasionally appear as a melodic interval. The most often used melodic intervals, however, are the major second, minor third, perfect fourth, perfect fifth, and octave. [12]
The main instrument in the Lobi area of Ghana is the xylophone, some of which are tuned to a tetratonic scale. [13] In eastern Uganda, the Gwere use for their six-string harp (called tongoli) a tetratonic scale in which all the intervals are nearly equal, which to Western ears sounds like a chain of minor thirds. [14]
In South Africa, the San use a tetratonic scale approaching 5 equal temperament, but lacking the second step. [15]
Tetratonic, as well as tritonic scales, were commonly used by the tribal peoples of India, such as the Juang and Bhuyan of Orissa state. [16]
The music of the Volga-Finnic Cheremis (Mari people) of central Russia was primarily pentatonic, but used tetratonic scales 20% of the time. [17]
The second-earliest scales of Scandinavian, German, English, and Scottish folk music are believed to have been pentatonic, themselves developed from an earlier tetratonic scale. [18] [ failed verification ] Tetratonic scales, along with pentatonic scales, account for 54% of songs in the traditional joik repertoire of the European Arctic Sami people, where the singing range extends to a tenth or eleventh. [19]
The predominant style of traditional music from the Peloponnese region of Greece is a mixture of Christian, Albanian, and Vlach. It employs tetratonic, pentachordal, and pentatonic scales, around the notes of which microtonal ornamentation (stolidia/psevtikes) occurs. [20]
A rare example of an art-music composition based entirely on a tetratonic scale is the early minimalist work Reed Phase (1966), by Steve Reich, which is based entirely on a single five-note cell, or "basic unit", repeated continually throughout the entire work. Because the note A occurs twice in this pattern, there are only four pitches in all. [21]
In music, a glissando is a glide from one pitch to another. It is an Italianized musical term derived from the French glisser, "to glide". In some contexts, it is distinguished from the continuous portamento. Some colloquial equivalents are slide, sweep, bend, smear, rip, lip, plop, or falling hail.
Staccato is a form of musical articulation. In modern notation, it signifies a note of shortened duration, separated from the note that may follow by silence. It has been described by theorists and has appeared in music since at least 1676.
Dorian mode or Doric mode can refer to three very different but interrelated subjects: one of the Ancient Greek harmoniai ; one of the medieval musical modes; or—most commonly—one of the modern modal diatonic scales, corresponding to the piano keyboard's white notes from D to D, or any transposition of itself.
The Aeolian mode is a musical mode or, in modern usage, a diatonic scale also called the natural minor scale. On the white piano keys, it is the scale that starts with A. Its ascending interval form consists of a key note, whole step, half step, whole step, whole step, half step, whole step, whole step. That means that, in A aeolian, you would play A, move up a whole step to B, move up a half step to C, then up a whole step to D, a whole step to E, a half step to F, a whole step to G, and a final whole step to a high A.
The Locrian mode is the seventh mode of the major scale. It is either a musical mode or simply a diatonic scale. On the piano, it is the scale that starts with B and only uses the white keys from there. Its ascending form consists of the key note, then: half step, whole step, whole step, half step, whole step, whole step, whole step.
A pentachord in music theory may be either of two things. In pitch-class set theory, a pentachord is defined as any five pitch classes, regarded as an unordered collection. In other contexts, a pentachord may be any consecutive five-note section of a diatonic scale. A pentad is a five-note chord.
The year 1648 in music involved some significant events.
Ionian mode is a musical mode or, in modern usage, a diatonic scale also called the major scale.
The first decade of the 16th century marked the creation of some significant compositions. These were to become some of the most famous compositions of the century.
Portato, also mezzo-staccato, French notes portées, in music denotes a smooth, pulsing articulation and is often notated by adding dots under slur markings.
Solos for a German Flute a Hoboy or Violin with a Thorough Bass for the Harpsichord or Bass Violin Compos'd by Mr. Handel was published by John Walsh in 1732. It contains a set of twelve sonatas, for various instruments, composed by George Frideric Handel. The 63 page publication includes the sonatas that are generally known as Handel's Opus 1.

A monotonic scale is a musical scale consisting of only one note in the octave. Having a deliberate fixed note, the monotonic is still a musical form rather than a total absence of melody. The monotonic stands in contrast to more common musical scales, such as the pentatonic and modern, common Western heptatonic and chromatic scales.
The Grupo renovación was an Argentine composers' association founded in 1929 to promote modern music.
