A ditonic scale is a musical scale or mode with two 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. Ethnomusicologist Bruno Nettl noted that ditonic scales were common in many parts of the world but often limited to specific music types, such as children's songs, with the exception of some tribal societies.

Distribution

Russia

The Cheremis (Mari people) of Russia employ ditonic scales in children's songs, generally with the two notes a minor third apart. Nettl theorised that these ditonic songs may be a remnant of a more archaic form of music. [2]

Peru

The Shipibo people of Amazonian Peru used ditonic scales in approximately 2.5% of their music. The ditonic was found "almost exclusively in the complex ostinato songs." [3]

Vietnam

The ca dao folk poetry of Vietnam is sometimes sung in ditonic scales. [4]

North America

Several ditonic scales were noted about the Modoc and Klamath tribes of the North American West Coast, and are also found in the Great Plains in the rituals of the 1800s Ghost Dance religion. [5] The scale was also used in the music of the Shawnee. [6]

India

The ditonic scale type is recognised in Indian music, and termed the Dvisvara ("two tone"), but ditonic scales are not recognised as raga scales. [7]

Nigeria

The ditonic is among the scale types employed in traditional Nigerian music. [8]

Maori

In a study carried out in 1969, Mervyn McLean noted that among the Maori tribes he surveyed, ditonic scales comprised 17% of the scales used. [9]

<i>Raga</i> Melodic mode in Indian music

A raga or raag is a melodic framework for improvisation akin to a melodic mode in Indian classical music. The rāga is a unique and central feature of the classical Indian music tradition, and as a result has no direct translation to concepts in classical European music. Each rāga is an array of melodic structures with musical motifs, considered in the Indian tradition to have the ability to "colour the mind" and affect the emotions of the audience.

Indian classical music Classical music from the Indian subcontinent

Indian classical music is the classical music of the Indian subcontinent. It has two major traditions: the North Indian classical music known as Hindustani and the South Indian expression known as Carnatic. These traditions were not distinct until about the 15th century. During the period of Mughal rule of the Indian subcontinent, the traditions separated and evolved into distinct forms. Hindustani music emphasizes improvisation and exploration of all aspects of a raga, while Carnatic performances tend to be short composition-based. However, the two systems continue to have more common features than differences.

When speaking of the music of Syria, it is important to remember that there are certain musical traditions and practices that have been present in Syria longer than others. There have been musical influences introduced into Syria through multiple eras of conquest and influences from surrounding cultures in modern-day Syria. Lying near Egypt and Israel, and connected to southern Europe by the Mediterranean, Syria became host to many distinct cultural musics through trade and route. The music present in Syria is related greatly to poetry, influenced greatly by the Bedouin nomadic tribes, the maqam system in Arabic classical music, as well as influenced greatly by the geopolitical movement and conflict in the Middle East. Syrian music generally has a singer who is accompanied by three or four instruments. The texture is usually thin but can become denser depending on the use of each instrument. Music is tightly linked to poetry in Syria.

Pueblo music includes the music of the Hopi, Zuni, Taos Pueblo, San Ildefonso, Santo Domingo, and many other Puebloan peoples, and according to Bruno Nettl features one of the most complex Native American musical styles on the continent. Characteristics include common use of hexatonic and heptatonic scales, variety of form, melodic contour, and percussive accompaniment, melodic range averaging between an octave and a twelfth, with rhythmic complexity equal to the Plains Indians musical sub-area.

The Arapaho are a tribe of Native Americans from the western Great Plains, in the area of eastern Colorado and Wyoming. Traditional Arapaho music, described by Bruno Nettl, includes sacred and secular songs. Traditional music uses terraced descent type melodic motion, with songs consisting of two sections, each with a range of more than an octave and scales of four to six tones.

The filmi-ghazal is a genre of filmi music based on ghazal poetry in Hindustani (Hindi-Urdu), used in Indian films, especially the music of Bollywood. The filmi-ghazals retain the couplet format and rhyme scheme similar to that in ghazals. However, instead of vocal or instrumental passages as interludes, the filmi-ghazal usually uses precomposed musical pieces.

Alankara, also referred to as palta or alankaram, is a concept in Indian classical music and literally means "ornament, decoration". An alankara is any pattern of musical decoration a musician or vocalist creates within or across tones, based on ancient musical theories or driven by personal creative choices, in a progression of svaras. The term alankara is standard in Carnatic music, while the same concept is referred to as palta or alankara in Hindustani music.

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 scale, both common in modern Western music. Tetratonic scales are not common in modern art music, and are generally associated with prehistoric music.

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.

A tritonic scale is a musical scale or mode with three notes per octave. This is in contrast to a heptatonic (seven-note) scale such as the major scale and minor scale, or a dodecatonic scale, both common in modern Western music. Tritonic scales are not common in modern art music, and are generally associated with indigenous and prehistoric music.
