Chromatic scaleThe chromatic scale (or twelve-tone scale) is a set of twelve pitches (more completely, pitch classes) used in tonal music, with notes separated by the interval of a semitone. Chromatic instruments, such as the piano, are made to produce the chromatic scale, while other instruments capable of continuously variable pitch, such as the trombone and violin, can also produce microtones, or notes between those available on a piano. Most music uses subsets of the chromatic scale such as diatonic scales.
Religious musicReligious music (also sacred music) is a type of music that is performed or composed for religious use or through religious influence. It may overlap with ritual music, which is music, sacred or not, performed or composed for or as ritual. Religious songs have been described as a source of strength, as well as a means of easing pain, improving one's mood, and assisting in the discovery of meaning in one's suffering. While style and genre vary broadly across traditions, religious groups still share a variety of musical practices and techniques.
HomophonyIn music, homophony (həˈmɒf(ə)niː,_hoʊ-;, Greek: ὁμόφωνος, homóphōnos, from ὁμός, homós, "same" and φωνή, phōnē, "sound, tone") is a texture in which a primary part is supported by one or more additional strands that provide the harmony. One melody predominates while the other parts play either single notes or an elaborate accompaniment. This differentiation of roles contrasts with equal-voice polyphony (in which similar lines move with rhythmic and melodic independence to form an even texture) and monophony (in which all parts move in unison or octaves).
DafDaf (دف) also known as Dâyere and Riq is a Middle Eastern (mainly Iranian) frame drum musical instrument, used in popular and classical music in South and Central Asia. It is also used in Afghanistan, Azerbaijan, Tajikistan, Iran, Uzbekistan, many regions of Georgia, Pakistan as well as in parts of India and Russian polar regions. It is also popular among Balkans, Bukharan Jews, Caucasians, Kurds, and Macedonians. Daf is the national musical instrument of Pakistan and is also depicted on the reverse and obverse of the Azerbaijani 1 qəpik coin and 1 manat banknote respectively, since 2006.
Music and mathematicsMusic theory analyzes the pitch, timing, and structure of music. It uses mathematics to study elements of music such as tempo, chord progression, form, and meter. The attempt to structure and communicate new ways of composing and hearing music has led to musical applications of set theory, abstract algebra and number theory. While music theory has no axiomatic foundation in modern mathematics, the basis of musical sound can be described mathematically (using acoustics) and exhibits "a remarkable array of number properties".
OudThe oud (عود, ʕuːd;) is a short-neck lute-type, pear-shaped, fretless stringed instrument (a chordophone in the Hornbostel–Sachs classification of instruments), usually with 11 strings grouped in six courses, but some models have five or seven courses, with 10 or 13 strings respectively. The oud is very similar to other types of lute, and to Western lutes since Western lutes were developed out of the Medieval Islamic Oud.
EthnomusicologyEthnomusicology is the study of music from the cultural and social aspects of the people who make it. It encompasses distinct theoretical and methodical approaches that emphasize cultural, social, material, cognitive, biological, and other dimensions or contexts of musical behavior, in addition to the sound component. Within musical ethnography it is the first-hand personal study of musicking as known as the act of taking part in a musical performance.
