larynx during phonation at various pitch and dynamic levels? A complete physiological action chart h needed.
Problem 36. How does the force of the expiratory blast of sub-glottic air (breath) affect the raising of the larynx in low and high pitched vocal tone production? What muscular action controls the stability of the larynx during phonation?
Problem 3J* Can an accurate mechanical working model of the larynx be constructed, showing all the parts of the living larynx in their exact inter-relationships? Cadaveric dissection studies and acoustical measurements of each tonal product of the larynx would be helpful.
Problem 38. How may reeducational training techniques be applied to the correction of irregularities in the vocal vibrato such as a too rapid vibrato? too slow vibrato? too wide (more than a semitone)? too narrow? too strong? too weak?
Problem 39. Can teaching and testing procedures be devised that would measure the efficacy of mental imagery and tonal anticipation in controlling the accuracy of pitch attack on single notes and in phrases; and in interval jumps at various dynamic levels?
Problem 40. Can off-pitch singing (i.e., sharping and flatting at various levels) during single note attacks and interval jumps be related to sub-glottal breath pressure and the control of respiration? How can standardized teaching techniques for correcting such faults be developed? Problem 41. Can testing procedures be devised for compiling objective evidence of the efficacy of mouth position in improving phonation? Also for testing the influence of lips, tongue position, palatal height, and level of larynx on phonation?
Problem 42. How can the effect of teaching the "open throat" concept in singing be tested objectively under conditions of direct control and indirect control (as in yawning)?
Problem 43. How does the muscular tonus of the body affect phonation in normal health? During conditions of bodily fatigue? After rest or a refreshing sleep? Before and after a meal? During various emotional states such as stage fright, joyous enthusiasm, dejection, etc.? In various conditions of bodily health and activity?
Problem 44. Can the muscles of phonation be exercised independently of the singing act? Develop a system of simple graded exercises for silently or audibly warming-up the laryngeal and respiratory muscles before singing.
Problem 45. Can a list of simple but musically palatable songs be prepared to serve as warming-up exercise material in teaching singing? The use of slow, sustained tones within a moderate middle range of the voice |
