Udukku as we saw already, is a percussion instrument and used for Ayyappan Pattu or Ayyappan Vilakku in Kerala. Ayyappan Pattu is a ritual performed by the devotees of Lord Ayyappa. It is also known as Sastham Pattu or Udukku Pattu. It is normally done before embarking on a journey to the Sabarimala Temple during the Mandalam Season.
The Ayyappan Pattu starts with Ganapathi Talam a rhythmic beat. The songs rendered depict stories from the life of Lord Ayyappa. Temporary temple of Lord Ayyappa, similar to the Sabarimala Temple is created with extensive decorations. There are specific troups who perform the Ayyappan Pattu. The players sing songs in tune with the beats of Udukku.
