IV Ca 2621h Transverse ceramic flute. Light-coloured body, unpainted, remains of engobe. Late Postclassic (ca. 1350-5121 AD). Origin High Valley of Mexico. Uhde Collection. The instrument has a short slit-shaped aeroduct (4.6 x 1.2 x 0.2 cm), a square section (1.2 x 0.3 cm) and a transverse tube with a handle hole. The applied element depicts the Aztec deity of music Xochipilli with his comb-shaped headdress, or the musician impersonated as a deity. In comparable flutes, the tube of the flute seems to represent a slit drum (teponaztli) on which the person depicted plays. A recording of this piece has already been made. The tone spectrum is A# +10 to C# +40 cents when the tube is closed and F -5 to G -10 cents when the tube is open. (Adje Both, 2004)
