Twenty-one attractive posters printed on one side of 17.5" x 23" paper and laminated for long-term durability have been prepared for display in the classroom. These posters present, with simplicity, numerous essentials of good singing. In reality, they can save teachers valuable teaching time as they demonstrate principles with easily-understood clarity. They embody the key concepts of many of the lessons in the Teaching Choral Concepts instructional program. Carefully prepared with strong student appeal, they capsulize many key concepts and make an attractive addition to the appearance of the classroom. They can be rotated or left in place for long-term student exposure. Some schools even have them posted in outside hallways because they draw the interest of potential program participants as well as present choir members. With proper care, they will last for years. The posters are: The Breathing Mechanism; Controlled Breathing; Vocal Ranges; Change-of-Color Points; Audition Criteria; Objectives of Vocal Training; The Singing Mechanism; Open Throat; Personal Warmup; Good Singing Tone; Attacks and Releases; Dynamic Levels; Extending Vocal Ranges; Basic Musical Styles; Correct Phrasing; Intonation; Phonetic Alphabet; Balance and Blend; Lip Positions for Singing the Vowels; Tongue Positions for Singing the Vowels; and Singing Consonants.
