When space between the mouth hole and the first hole for notes is ten fingers, the vaṁśī is called mahānanda (great delight) and sammohinī (the bewitcher). If the space is twelve fingers, the vaṁśi is called ākarṣiṇī (the attractor). If the space is fourteen fingers, the vaṁśī is called ānandinī (bliss-giver).
Purport
Kṛṣṇa has a longer vaṁśī, which is called mahānandā, or sammohinī. When it is still longer it is called ākarṣiṇī. When it is even longer it is called ānandinī. The ānandinī flute is very pleasing to the cowherd boys and is technically named vaṁśulī. These flutes were sometimes bedecked with jewels. Sometimes they were made of marble and sometimes of hollow bamboo. When the flute is made of jewels it is called sammohinī. When made of gold, it is called ākarṣiṇī.
