TRES:
    Cuban three-toned guitar
CUATRO:
    a Venezuelan four-stringed instrument
GUAJIRO:
    (Cuban country) artists
SON:
    basically the blues of Cuban music
SAUDADE:
    While the closest--and woefully inadequate--English translation is "yearning," saudade is similar emotionally to the Spanish notion of duende, and to that mysterious guiding force at work in Mississippi and Texas blues. Magalhaes explains, "Saudade is a state in which a person allows himself to experience contradictory feelings or cultivate nonlinear thoughts about love, life and time. For Madredeus, saudade is the key and the reason we make music."
