Introduction. Summary of investigator's questionnaire results ; Statement of the problem ; Need for the study ; Purpose of the study ; Hypotheses ; Definitions ; Limitations of the study ; Assumptions pertinent to the study -- Review of related literature. Acoustical factors of vocal production and performance affecting choral sound ; Choral sound (Choral blend ; Choral balance ; Intensity ; Vibrato ; Tone color ; Vowel uniformity ; Choral intonation ; Rhythm/precision) ; Choral formations (Placement of individual singers ; An interview with Weston Noble ; An interview with John Williams ; An interview with Rodney Eichenberger ; Favoring a variety of formations ; Visual/style criteria) ; Sectional versus mixed formations (Sectional formations ; Mixed formations) ; Room acoustics -- Materials and procedures. Design of the study ; Selection of treatment choirs and directors ; Selection of the choral pieces ; Selection of the panel of judge ; Instruments of evaluation (Choral sound inventory ; Singer evaluation survey ; Director evaluation survey) ; The site for the experiment ; Pre-experiment preparation. Preparation for the choir (Establishment of the mixed formations ; Establishment of the sectional formations) ; Preparation for the judges/pilot test ; The experiment/collection of data -- Presentation and analysis of data. Data and analysis for dependent variables (Overall blend ; Instances of noticeable individual voices ; Overall balance of voice parts/intensity ; Intonation ; Rhythmic precision/ensemble/diction ; Interpretation/expressiveness/dynamic control ; Testing of hypotheses ; Testing null hypotheses 1 and 2 (Overall blend ; Instances of noticeable individual voices ; Overall balance of voice parts/intensity ; Intonation ; Rhythmic precision/ensemble/diction ; Interpretation/expressiveness/dynamic control) ; Testing null hypotheses 3 and 4 as interacting hypotheses ; Testing hypotheses 3 and 4 separately (Overall blend ; Instances for noticeable individual voices ; Overall balance of voice parts/intensity ; Intonation ; Rhythmic precision/ensemble/diction ; Interpretation/expressiveness/dynamic control) ; Results of the singer evaluation survey (Question 1 comments ; Question 2 comments ; Question 3 comments) ; Results of the director evaluation survey (Results of the DES for director 1 ; Results of the DES for director 2) -- Summary and conclusions. Purpose of the study ; Procedures ; The treatment choirs ; The choral pieces ; The panel of judges ; Instruments of evaluation ; The site for the experiment ; The experiment/collection of data ; Results. Analysis and discussion of the effect of independent variables on each dependent variable (Overall blend ; Instances of noticeable individual voices ; Overall blend of voice parts/intensity ; Intonation ; Rhythmic precision/ensemble/diction ; Interpretation/expressiveness/dynamic control) ; Results of hypotheses testing (Results of the test for null hypotheses 1 and 2 ; Results for testing null hypotheses 3 and 4 as interacting hypotheses) ; Results for null hypotheses 3 and 4 tested separately (Overall blend ; Instances of noticeable individual voices ; Overall balance of voice parts/intensity ; Intonation ; Rhythmic precision/ensemble/diction ; Interpretation/expressiveness/dynamic control) ; Summary of the results of the singer evaluation survey and the director evaluation survey ; Conclusions ; Discussion and implications ; Recommendations for further research -- Appendices.
