The study was an action research to assist bandsmen of the College of Technology (COLTEK), University of Education, Winneba (UEW) in Ghana, within a short period of time, to perform at the University's Congregation ceremony. A preliminary diagnostic test conducted revealed among the challenges encountered by the bandsmen as inability to read musical staff notation, and then limited knowledge of keys and their scales. Observations, auditioning and personal interactions were employed as data collection instruments while solfege, varied rehearsal techniques and phrase by phrase approaches were used as the main interventions. Hinged on the theory of expectation, the paper concludes that with the appropriate rehearsal techniques, a band can be prepared within a short time to gain proficiency for public performances in spite of its infantile nature and the less knowledge in theory among the bandsmen. It is recommended that the interventions are employed by tutors and trainers of new bands to deal with fundamental instrumental playing techniques for public performances.
