Oladipo noted that a lot was learnt about acquiring knowledge as regards other people's culture and tradition, while classifying musical instruments in Africa into four typologies: the membranophones which are based on membranes (drums); the chordophones based on strings; the aerophones
that are dependent on blowing the air and Idiophone which makes music by striking and shaking nature.
The zoolophone is an idiophone--an instrument that produces sound through its own vibration rather than employing strings (chordophones), columns of air (aerophones
), or membranes (membranophones).
Litwiniec (sax, aerophones
, throat-singing and ethno instruments), Igor Gawlikowski (guitarist, composer and arranger) and Pawe?
It is interesting to reflect that in spite of its significant exposure on the Internet the qeej has not followed the trajectory of its fellow aerophones
, the Japanese bamboo flute shakuhachi and the Indigenous Australian didjeridu, on the voyage into the realms of the "world music" scene.
They are both lip-vibrated aerophones
. Frequently, each of these horns provides the inner voicing for the various ensembles and, on occasion, emerges as a leading and even solo voice.
To categorize instruments, I employ the modern classification system (Hornbostel and Sachs), which classifies all instruments into four main categories according to the way in which sound is produced: aerophones
, idiophones, membranophones and chordophones.
For this reason, the material included in it needs be organised according to systematic organologic international classification, by historic and literature resources, by autonomous communities and by the different instruments used (aerophones
, cordophones, instruments of the lute's family, and percussion).
Chapter Four is an overview of Kaulong solo instrumental music which is played exclusively on aerophones
, otherwise known as wind instruments: lawi (raft panpipes), laresup and lasevarut (bundle panpipes), and lapilue (end-blown flute)--instruments that are often played in a programmatic way (that is, to tell a story, or depict an event or a character) and that can act as speech surrogates to express what otherwise remains unspoken.
The author chose to organize the organology section by first addressing general, historical, and regional studies of Spanish instruments, followed with the organological divisions of aerophones
, chordophones, idiophones, and membranophones.
