A slit drum or slit gong is a hollow percussion instrument. In spite of its often being called a drum, it is not a true drum because it lacks a drumhead, the membrane stretched across the top of a true drum. It is classed instead as an idiophone in which the entire instrument vibrates.
A slit drum is usually carved or constructed from bamboo or wood, in the form of a mostly closed hollow chamber with one or more slits in it. It is played by striking near the edge of the slit. In some designs, the slit is a single straight line; in others, the slit is used to create one or more "tongues", achieved by cutting three sides of a rectangular (or similar) shape and leaving the fourth side attached. Most slit drums have one slit, though two and three slits (often resembling an "H" and thereby forming two tongues) occur. Tongues of different areas or thicknesses will produce different pitches. Slit drums are used throughout Africa, Southeast Asia, and Oceania. In Africa, such drums are situated in strategic locations for optimal acoustic transmission (e.g., along a river or valley), in order to be used for long-distance communication. [1]
The ends of a slit drum are closed so that the shell becomes the resonating chamber for the sound vibrations created when the tongues are struck, usually with a stick or mallet. The resonating chamber increases the volume of the sound produced by the tongue and presents the sound through an open port. If the resonating chamber is the correct size for the pitch being produced by the tongue, which means it has the correct volume of airspace to complete one full sound wave for that particular pitch, the instrument will be more efficient and louder.
The people of Vanuatu create a similar instrument out of a large log. In most islands, the drum lies horizontally on the ground. [2] In the central islands, slit drums are erected vertically, and adorned with carvings on the outer surface, representing spirits. While traditional on one island only, this adorned type of drums have become one of the national emblems of Vanuatu as a whole.
The wooden fish works like a slit drum but is rarely classified with the other slit drums.
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.
Kulintang is a modern term for an ancient instrumental form of music composed on a row of small, horizontally laid gongs that function melodically, accompanied by larger, suspended gongs and drums. As part of the larger gong-chime culture of Southeast Asia, kulintang music ensembles have been playing for many centuries in regions of the Southern Philippines, Eastern Malaysia, Eastern Indonesia, Brunei and Timor, Kulintang evolved from a simple native signaling tradition, and developed into its present form with the incorporation of knobbed gongs from Sundanese people in Java Island, Indonesia. Its importance stems from its association with the indigenous cultures that inhabited these islands prior to the influences of Hinduism, Buddhism, Islam, Christianity or the West, making kulintang the most developed tradition of Southeast Asian archaic gong-chime ensembles.
Developed and used by cultures living in forested areas, drums served as an early form of long-distance communication, and were used during ceremonial and religious functions.
A lamellophone is a member of the family of musical instruments that makes its sound by a thin vibrating plate called a lamella or tongue, which is fixed at one end and has the other end free. When the musician depresses the free end of a plate with a finger or fingernail, and then allows the finger to slip off, the released plate vibrates. An instrument may have a single tongue or a series of multiple tongues.
The marímbula is a plucked box musical instrument of the Caribbean. In Cuba it is common in the changüí genre, as well as old styles of son. In Mexico, where it is known as marimbol is played in son jarocho; in the Dominican Republic, where it is known as marimba, it is played in merengue típico, and in Jamaica it is known as rumba box and played in mento.
Igbo music is the music of the Igbo people, who are indigenous to the southeastern part of Nigeria. The Igbo traditionally rely heavily on percussion instruments such as the drum and the gong, which are popular because of their innate ability to provide a diverse array of tempo, sound, and pitch. Igbo music is generally lively, upbeat, and spontaneous which creates a variety of sounds that enables the Igbo people to incorporate music into almost all the facets of their daily lives. Some very popular Igbo musical styles are Igbo highlife, Ogene, Igbo gospel.
The kagul is a type of Philippine bamboo scraper gong/slit drum of the Maguindanaon and Visayans with a jagged edge on one side, played with two beaters, one scraping the jagged edge and the other one making a beat. The Maguindanaon and the Banuwaen use it in the rice paddies to guard against voracious birds, using the sound it produces to scare them away. The Maguindanaon and the Bukidnon also used to use it for simple dance rhythms during social occasions. The rhythms were usually simplistic in nature, consisting of one rhythmic pattern sometimes combined with another. Use of the kagul in the former way is no longer practiced.
The agung is a set of two wide-rimmed, vertically suspended gongs used by the Maguindanao, Maranao, Sama-Bajau and Tausug people of the Philippines as a supportive instrument in kulintang ensembles. The agung is also ubiquitous among other groups found in Palawan, Panay, Mindoro, Mindanao, Sabah, Sulawesi, Sarawak and Kalimantan as an integral part of the agung orchestra.
The babandil is a single, narrow-rimmed Philippine gong used primarily as the “timekeeper” of the Maguindanao kulintang ensemble.
The gandingan is a Philippine set of four large, hanging gongs used by the Maguindanao as part of their kulintang ensemble. When integrated into the ensemble, it functions as a secondary melodic instrument after the main melodic instrument, the kulintang. When played solo, the gandingan allows fellow Maguindanao to communicate with each other, allowing them to send messages or warnings via long distances. This ability to imitate tones of the Maguindanao language using this instrument has given the gandingan connotation: the “talking gongs.”
Struck idiophones is one of the categories of idiophones that are found in the Hornbostel-Sachs system of musical instrument classification.
The music of the ancient Mayan courts is described throughout native and Spanish 16th-century texts and is depicted in the art of the Classic Period. The Maya played instruments such as trumpets, flutes, whistles, and drums, and used music to accompany funerals, celebrations, and other rituals. Although no written music has survived, archaeologists have excavated musical instruments and painted and carved depictions of the ancient Maya that show how music was a complex element of societal and religious structure. Most of the music itself disappeared after the dissolution of the Maya courts following the Spanish Conquest. Some Mayan music has prevailed, however, and has been fused with Spanish influences.
A teponaztli is a type of slit drum used in central Mexico by the Aztecs and related cultures.
An Ikoro is a musical instrument created and used by the Igbo of Nigeria. It is a slit drum that is beaten with a stick or sticks and can be used in some parts of Igbo land for communicating, similar to a talking drum. Ikoro cannot be played by anyone. It is so special that any time its sound is heard people will gather at the village square. As soon as it sounds, people around assume that any of the following has happened: murder, land has been defiled, an outbreak of war, a calamity has befallen the community, etc. Any time the ikoro is heard, people gather at the village square to hear the latest developments. Ikoro also brings a sense of urgency.
Ogene is a style of Igbo music consisting of, and taking its name from, the ogene instrument, which is a large metal bell. The Ogene instrument has historically been made by the Igbo people of Nigeria. It is one of the most important metal instruments of the people.
Philippine traditional musical instruments are commonly grouped into four categories: aerophones, chordophones, membranophones, and idiophones.
A steel tongue drum, tank drum, or hank drum is a round steel slit/tongue drum in the idiophone family originally fashioned from a propane cylinder.
Bamboo's natural hollow form makes it an obvious choice for many musical instruments. In South and South East Asia, traditional uses of bamboo the instrument include various types of woodwind instruments, such as flutes, and devices like xylophones and organs, which require resonating sections. In some traditional instruments bamboo is the primary material, while others combine bamboo with other materials such as wood and leather.
The ọjà is an integral part of the rich cultural heritage of the Igbo people and continues to play a significant role in their musical traditions. The Igbo people, who are indigenous to Nigeria, are renowned for the utilization of the ọjà (flute) traditional musical instrument in cultural activities or events. It is made from bamboo or metal and is played by blowing air into one end while covering and uncovering holes along the body to create different notes. The ọjà, which is skillfully carved from wood, produces a beautiful sound when played during songs. In traditional Igbo music, the ọjà is often performed in conjunction with a number of other instruments such as the ekwe, udu, igba (drum), ogene (bell), ichaka/0sha (rattle), okwa (gong), etc. These instruments complement each other to create a unique and distinct sound that characterizes the musical traditions of the Igbo people. The seamless integration of these instruments in musical performances highlights the strong musical heritage and cultural identity of the Igbo people.
