The teacher is encouraged to be flexible and creative with them. Directors are encouraged to perform these in various combinations and sets. Feel free to be creative. For example, repeats could be added featuring various soloists and/or small groupings in contrast with the full group (as in a concerto.) Creativity could be promoted by allowing students to make suggestions pertaining to the formal organization of the material. In addition to decisions as to which pieces to perform directors are encouraged to involve students in making creative decisions such as which ones to put together, which phrases to repeat in various combinations and instrumental subsets and other appropriate aesthetic decisions. Each piece could function as a locus for branching into various content areas in connection with social studies, integrated curriculum and/or inquiry. Many of the melodies have very smooth and conjunct voice leading making them excellent for solfege/sight-reading training. These melodies are offered as a resource for the teacher to use in a variety of ways and possibilities are unlimited. Lyrics are readily available online.
