The Tooka is a two person flute. The current version of the Tooka uses two identical sections of hollow flexible tube connected together with a plastic connector to form one continuous tube. At each end is a mouth-piece made from a connector, four buttons and a pressure sensor. The tube’s outside and inside diameters are 1.25” and 1”, respectively, providing a fairly high compliance. When assembled, the Tooka measures 86cm long.
