Preparation
The key may be established by having the students sing scales or chord patterns. Students may sing random intervals or patterns such as 1-3-5-3-1, 1-4-6-4-1, etc. Directors only may sing with the choir during the warm-up to establish keyality. Directors may not illustrate by singing intervals directly referenced from the exercise.
When discussing the exercise, the director may point out potentially problematic intervals. They may not rehearse these with the choir.
Singers of the same voice part are permitted to discuss and sing with their neighbors during the prep time. This practice of “neighboring” is limited to 2 or 3 students. The “neighboring” groups may not join together and prepare as a section. In addition, students may practice the example up to 4 in a group with only 1 on a voice part.
