Hornbostel–Sachs in the context of "Flute"

The lyre (/ˈlaɪər/) (from Greek λύρα and Latin lyra) is a stringed musical instrument that is classified by Hornbostel–Sachs as a member of the lute family of instruments. In organology, a lyre is considered a yoke lute, since it is a lute in which the strings are attached to a yoke that lies in the same plane as the sound table, and consists of two arms and a crossbar.

The lyre has its origins in ancient history. Lyres were used in several ancient cultures surrounding the Mediterranean Sea. The earliest known examples of the lyre have been recovered at archeological sites that date to c. 2700 BCE in Mesopotamia. The oldest lyres from the Fertile Crescent are known as the eastern lyres and are distinguished from other ancient lyres by their flat base. They have been found at archaeological sites in Egypt, Syria, Anatolia, and the Levant. In a discussion of the Nubian lyre, Carl Engel notes that modern Egyptians call it qytarah barbarîyeh, reflecting its association with the Barbaras (Berbers)—linked to the brbrta of ancient Egyptian references to Punt, a region identified with present-day Somalia, where the shareero lyre remains in use.

Yoke lutes, commonly called lyres, are a class of string instruments, subfamily of lutes, indicated with the codes 321.21 and 321.22 in the Hornbostel–Sachs classification.

A lute (/ljuːt/ or /luːt/) is any plucked string instrument with a neck and a deep round back enclosing a hollow cavity, usually with a sound hole or opening in the body. It may be either fretted or unfretted.

More specifically, the term "lute" commonly refers to an instrument from the family of European lutes, which were themselves influenced by short-necked lutes in Gandhara (modern-day Pakistan) which became the predecessor of the Islamic, the Sino-Japanese and the European lute families. The term also refers generally to any necked string instrument having the strings running in a plane parallel to the sound table (in the Hornbostel–Sachs system).

The drum is a member of the percussion group of musical instruments. In the Hornbostel–Sachs classification system, it is a membranophone. Drums consist of at least one membrane, called a drumhead or drum skin, that is stretched over a shell and struck, either directly with the player's hands, or with a percussion mallet, to produce sound. There is usually a resonant head on the underside of the drum. Other techniques have been used to cause drums to make sound, such as the thumb roll. Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years.

Drums may be played individually, with the player using a single drum, and some drums such as the djembe are almost always played in this way. Others are normally played in a set of two or more, all played by one player, such as bongo drums and timpani. A number of different drums together with cymbals form the basic modern drum kit. Many drums are played together with other instruments.

The triangle, or musical triangle, is a musical instrument in the percussion family, classified as an idiophone in the Hornbostel-Sachs classification system. Triangles are made from a variety of metals including aluminum, beryllium copper, brass, bronze, iron, and steel. The metal is bent into a triangular shape with one open end. The instrument is usually held by a loop of some form of thread or wire at the top curve to enable the triangle to vibrate, and it is struck with a metal rod called a "beater". The triangle theoretically has indefinite pitch, and produces a plurality of overtones when struck with an appropriate beater.

Curt Sachs (German: [zaks]; 29 June 1881 – 5 February 1959) was a German musicologist. He was one of the founders of modern organology (the study of musical instruments). Among his contributions was the Hornbostel–Sachs system, which he created with Erich von Hornbostel.

The oud (/uːd/ OOD; Arabic: عُود, romanized: ʿūd, pronounced [ʕuːd]) is a Middle Eastern 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 similar to other types of lute, and to Western lutes which developed out of the Medieval Islamic oud. Similar instruments have been used in the Middle East, some predating Islam, such as the barbat from Persia. Different versions of the oud are used in Arabia, Turkey, and other Middle Eastern and Balkan regions. The oud, as a fundamental difference with the western lute, has no frets and a smaller neck. It is the direct successor of the Persian barbat lute. The oldest surviving oud is thought to be in Brussels, at the Museum of Musical Instruments.
