The term "timbal" or "timbales" (pl.) has been used in Cuba for two quite different types of drum. "Timbales" is the Spanish word for timpani (kettledrums), an instrument that was imported into Cuba in the 19th century and used by wind orchestras known as orquestas típicas. These were the same general type of drum used in military bands, perhaps slung either side of a horse, and in classical orchestras. These were, and are, played with mallets (sticks with large, soft, round heads). The timpani were replaced by pailas criollas, which were originally designed to be used by street bands. Pailas are always hit with straight batons (thicker than standard drumsticks, and not shaped: they are of uniform thickness along the length) that have no additional head. Hits are made on the top and on the metal sides. In a modern band the timbalero may also have a trap set to switch to for certain numbers.
