In Phonetics , a trill is a Consonant al sound produced by vibrations between the articulator and the Place Of Articulation . Spanish <rr> as in ''perro'' is an Alveolar Trill , while the Portuguese <rr> is almost always Uvular . Trills are very different from Flaps . Whereas with a flap (or tap), a specific gesture is used to strike the active articulator against the passive one, in the case of a trill the articulator is held in place, where the airstream causes it to vibrate. Usually a trill vibrates for 2-3 ''periods'', but may be up to 5, or even more if Geminate . However, trills may also be produced with only a single period. While this might seem like a flap, the articulation is different; trills will vary in the number of periods, but flaps do not.

The coronal trill is most frequently Alveolar , but Dental and Postalveolar articulations and also occur.
