Salidumay is not a folk dance but is a folk song. It is syllabic and the lines do not end in rhyme but in assonace. It is a lullaby chant among the natives of the Cordillera mountains, specifically the Kalinga tribe.
Consonance is when the sound of a consonant is repeated, either within one line or in the same place over a few lines. It could be considered a half rhyme, and usually alliteration is also consonance, but specifically at the start of a line. Basically it is assonace, but with consonants instead of vowels.
