A behavioral skills training package, including verbal instruction, modeling, rehearsal, and feedback, was used to teach children correct posture, defined as keeping feet on the floor, legs parallel to each other, and the back and neck perpendicular to the floor, during flute lessons. Three typically developing girls aged 8 to 9 years participated. All three students' posture improved from 0% during baseline to nearly 100% after training for all sessions, generalization probes, and after a 1- to 2-month follow-up. The training package was proven effective in the acquisition, generalization, and maintenance of correct posture for flute playing. (Contains 1 figure.)
