At the place where the stopper ends, a whistle hole is cut into the bark, and one end of the hole is bent slightly inwards. Three to six finger holes are cut in the pipe. Wooden pipes are made of ash or linden wood. The bark is removed, and the instrument is hollowed out by burning, drilling or carving. The blowing hole, whistle hole and finger holes are made in the same way as for the
Tin whistle tonic note of the first register; this makes it harder to accidentally drop into the first register and helps to correct pitch. Recorders perform this by "pinching" open the dorsal thumb hole. Various other notes (relatively flat or sharp with respect to those of the major scale) can be accessed by "cross fingering" techniques, and all the notes (except the lowest of each octave/register) can be flattened by "half holing". Perhaps the most effective and most used cross fingering is that which produces a flattened form of the seventh note (B instead of B on a C whistle, for example,
