The northern vicitrā ("colourful") vīṇā is structurally a hybrid of the bīṇ-sitār type: it has a wide neck (about 10 cm) which is flat on top and rounded in section beneath (about 3 cm deep), and pegs for the sympathetic strings set in the proximal side. The neck terminates on the right in an integrated, wood-covered resonator, which in some cases is smaller and pear-shaped, in others larger and similar to that of the sitar. The instrument rests on two large bottle-gourds which are screwed into the back of the neck. The main strings are tuned in descending 4ths and 5ths; the slider (baṭṭā) is a glass egg)
