Spanish Tinge
The phrase Spanish tinge is a reference to an Afro-Latin rhythmic touch that spices up the more conventional 4/4 rhythms commonly used in jazz and pop music. The phrase is a quotation from Jelly Roll Morton. In his Library of Congress recordings, after referencing the influence of his own French Creole culture in his music, he noted the Spanish (read Cuban) presence:
Now in one of my earliest tunes, "New Orleans Blues", you can notice the Spanish tinge. In fact, if you can't manage to put tinges of Spanish in your tunes, you will never be able to get the right seasoning, I call it, for jazz.
What Morton described as a "Spanish" influence did not refer to Spanish culture. What he called "Spanish" were the tresillo and habanera rhythms of the Cuban contradanza ("habanera"). Morton demonstrated the "tinge" to Alan Lomax in the 1938 Library of Congress recordings. What is known in Latin music as the habanera rhythm (also known as the congo,tango-congo, and tango.), and tresillo, are in fact, two of the most basic duple-pulse cells found in sub-Saharan African music traditions. They were brought to Cuba and elsewhere in the New World via the Atlantic slave trade.
