Ayiciano Compadre have a drink on me!
True it's that both Haiti and DR share the bond of African roots in their own respective music and dances, yet the conclusion reached in the text reading you exposed to start this thread points to the initiation of merengue by an Haitian, as you quite clearly pointed out Konpa shares many aspects and some similarities to the merengue, but it's more closely similiar to the earlier style of merengue "Mangulina" as it was called and still is, if you have been to the Campos in the DR and had the chance to be present at one of the many Fiestas de Palos you'll quickly notice the heavy use of African drums and beats by the percussioners, the chants and dances are African in all aspects and they keep the traditions of the early African slaves when they danced in the ritual and celebrations, the fact that Dominicans keep dancing to Merengue unchanged for a looooooong period of time it's a testament to the pride of a nation dancing the joy and singing thanks to our maker and saints, just as Papa Candelo, Anaisa, San Miguel, Osha and many others are still present today as strong as they were yester is in fact prove that African values are still embedded in the fabric of the Dominican culture to stay for a long time.
Just as Bachata came to be danced and heard in the Discos and dance floors from it's dark origins in the Bar and bordellos, Merengue came from the mountains and plains into the hall and ballrooms of the Dominican aristocracy to stay, nobody invented it, nobody struck the first Merengue, it just happened to be because it was danced and delighted the souls of many Dominicans tired from the toiling in the land and eased the aristocracy from their waltz and ballroom dances, it was and still is Merengue plain and simple a monument to the humbled beginings of two people that now share and island divided by color and language, and yes also by their distinctive dance and music...
