The present study investigates the prosody/pragmatics interface in TBLT by extending the traditional morphological focus-on-form to a focus on intonational forms, with Spanish declaratives and imperatives. Twenty-eight intermediate L2 Spanish learners were assigned to one of two conditions that differed in the type of focus-on-form present during the pre- and posttask phases of a focused, task-based intervention: focus on grammar (FOG) or focus on grammar + intonation (FOG + I). All participants were administered an oral discourse completion task in a pre- and a posttest that elicited Spanish imperatives and declaratives to measure gains. Results show that participants, regardless of condition, did not distinguish imperatives from declaratives using intonation in the pretest. However, participants in the FOG + I condition modified their pitch range and pitch accents in the posttest to signal a difference between imperatives and declaratives, though their use was different from the input provided by a native speaker instructor.
