The most common version of Thiyyattu involves four phases of presentation: a) Kalamezhuthu (sketching the kalam—picture—of Ayyappa using natural pigments), b) Kottum Pattum (rendition of invocatory songs of Ayyappa and a stylised narration of the story of his birth), c) Koothu gesture-laden dance enacting the build-up story to the delivery of the lord) and d) Velichchappaadu (the slow-paced to frenzied dance of the oracle who eventually erases the kalam—the image of the lord sketched on the sanctified floor).
The lord invariably holds his weapons like the sword and the bow-and-arrow, and, in more elaborate versions is sketched mounted on the tiger or the horse.
The songs—accompanied by the beats of 'para', a smaller version of the chenda, and the cymbals called ilathalam—praising the lord bear a mix of quaint old Malayalam and Tamil with a streak of endemic tunes, some of which can be traced to classical ragas of the Sopanam style of Kerala music besides that belonging to the Carnatic idiom.
The stylised rendition of the birth of Ayyappa, called Thottam, also sticks to the same mix of languages, but is devoid of music.
Facial emotions are nil, dance movements are minimal and hand gestures would look the less refined versions of Koodiyattam and Kathakali.
The Velichchappadu (oracle), wielding a small sword, is bare-chested but for the garland and, canonically, with a flowy hair; the face either bearded or clean-shaven.
The Thiyyadi Nambiar families, despite their existence in central Kerala, enjoy the popularity of their art more in the upstate Malabar belt.
Some experts/historians trace this pattern to the community's possible southward flee from their original north Malabar homes during the controversial temple destruction spree of the 18th-century Mysore king Tippu Sultan.
