The appropriate time signature for the songs 'O Ilaw' and 'Tango Rhythm' is 2/4.
While these music can also be written in any other time signature, encoding the music under 2/4 time signatures creates more emphasis on the notes than any other time signatures.
Harana songs become similar to the rhythmic styles of Spanish Tango or Habanera because they were commonly performed using the same musical instrument - a guitar. Also, these songs are traditionally performed in public display of romance, with the boy singing for the girl he loves.
