ano ang pinagkaiba ng kundiman at harana at the venn diagram
Harana
During a serenade, one can pretty much sing any love song he likes, even English ones, and still get away calling it a harana. But if you are going for a truly authentic harana experience like they did in old Philippines, you have to use a particluar set of songs specifically written for the endeavor. These songs were written by some of the better-known composers in the last 75 years such as Santiago Suarez, Constancio de Guzman and Antonio Molina, to name a few.
Kundiman
One of the main reasons kundiman is mistaken for a harana is because haranistas would oftentimes sing kundiman songs during a harana. See how easy it is to get confused? But make no mistake, harana and kundiman are stylistically different.
Whereas harana is in 2/4/ time, kundiman is in 3/4. The formula is verse 1 on minor key (e.g. C Minor) followed by verse 2 on parallel major key (C Major) midway through. This is intractable. Stray from this formula, and you no longer have a kundiman.
As mentioned, the language is also in archaic Tagalog but the theme subject is different from harana. Kundiman songs have a fatalistic woe-is-me streak to it. He is always heartbroken, very poor with nothing to offer other than his undying love, and willing to suffer, even die, to prove his love. In fact, the word kundiman is said to be the contraction of the phrase “kung hindi man” (if not, or if not meant to be).
