Have you ever thought of putting the harmony parts on a split track to help students singing the harmony parts? Many of the music book series that are available to teachers in regular music classes supply this as a guide and teaching aid for students. Not all students are used to singing harmony and this would be such a time saving tool when working with students who have little music training as I have frequently encountered. We are not allowed to audition students before they are placed in our musical theatre class. We audition for parts at the beginnig of the semester. Students come to us with a variety of musical backgrounds from many years performing to the very first time music student. A split track requires turning off one speaker to make the other part more prominent. This would make my life SOOOO much easier with the novice singers. Thanks! I really do find the MTI Show Kits to be the best available (just thought I would ask for a little time saver which could make things easier for the Music Director!).
