Purpose
The apito de samba ("samba whistle") is used during performances ofTypes of apitos
Samba band leaders can choose to either play a single-tone apito – common referee whistle – or a tri-tone apito. Apitos were traditionally made of wood, but now most are made of metal. The whistle is a chamber that has a small ball or dowel rod inside. When one blows air through the mouthpiece, the small ball or dowel rod moves around the chamber and hits its sides.Sound characteristics
Since, the apito de samba has a small ball or dowel rod that hits the sides of the whistle's chamber, this instrument creates a loud and shrill sound, which is useful in a samba school because the sound can be heard over the playing of the band. However one can manipulate the sound of the whistle by changing the speed at which one is blowing air through the instrument and by changing one's embouchure. Audio example of variations in apito de samba can be found online. Sound of a wood samba whistle can be also heard online (1:46 – 2:08).Single-tone vs tri-tone apitos
Band leaders using single-tone apitos can choose to hold the instrument between their teeth and create signals with both the whistle and their hands to conduct. Band leaders with tri-tone apitos hold the instrument with one hand and can use the other hand to conduct. Tri-tone apitos have three holes – one on the top, one on the left, and one on the right. One can manipulate the pitch being played by covering either or both of the holes on the sides of the instrument using a thumb and/or index finger. Covering none of the holes creates the highest pitch, while covering either of the two side holes creates the middle pitch, and covering both side holes creates the apito’s lowest pitchReferences
