Pitch stone typically has a density around 2.3 - 2.8 g/cm³, depending on the specific composition and porosity of the sample.
There are three kinds of dizi.Bangdi - short dizi, with relatively high pitch.Qudi - medium sized dizi, with a lower pitch. It is normally 40 cm (about 15.75 in.) or more in length.Large dizi - long dizi, which have a seventh finger hole. The large dizi was invented just in recent decades
