Fluier The Fluier one of the most widespread Moldovan folk instruments consisting of a small wooden tube with a few holes. It is with this tube that the magical capacity of man to identify on the hostile forces the fire that unleashed, to tame the wild animals, to fight with the evil towards the triumph of the good is identified in the Moldavian folk tales.

The Fluier has a lot of variants of different sizes, with or without don with a varied number of holes or without them, such as tilinca or larger sizes such as horse. Another variant of the once widespread whistle was the twin whistle composed of two parallel tubes fixed to each other that could be played with double notes. The whistle remains a melodic instrument on a single voice that is also used as a solo instrument in the folk music orchestra.

The cause of the vibrations of the air column in the whistle is the change of movement and the formation of the air layer caused by the blow of the edge air column (the tongue of the whistle) by the vibration of the reed (bagpipes, taragot, drâmbă and baian). Consequently, the initial, simple, linear air flow is transformed into a turbine one and in the instrument tube some logitudinal waves are formed, which produce the sound effect of a certain frequency and which depend on the intensity of the blown air.
