The floyara (Floyarka) is a more perfected form of the sopilka. It is characterized as an open ended notched flute. The floyara is a pipe of approximately a metre in length. One end is sharpened and the breath is broken against one of the sides of the tube at the playing end. Six holes in groups of three are burnt out in the centre of the instrument. It was often played at funerals in the Carpathian mountains. The floyarka is a smaller version of the floyara and is similar to the sopilka and frilka. The floyara is approximately 60 cm (24 in) long. The mouthpiece is sharpened into a cone-like edge and the instrument produces a sound similar to that of the flute. Shepherds were also able to accompany themselves with glutteral humming which produced an ostinato tone or drone. The floyarka is often called a frilka or sometimes zubivka in central Ukraine.
The name is rather a contaminant from a Greek-Romanian filliation (more spread is the Slavic sopilka).
