Numerous studies exist examining the link in solo singers between timbre and overtone spectra. The purpose of this study is to examine if similar results can be obtained by applying the same techniques to choral singing. The study is aimed at non-scientific readers and therefore introduces the subject with background to the relevant physics. In this study a number of recorded samples of choirs were taken from www.youtube.com and analyzed. The analysis included computation of long-term average spectra (LTAS) and singing power ratio‟s (SPR), which provided an indication of the relative energy in the higher overtone region of every choir. This was compared to a binary value judgment of the choirs. The results indicate that the SPR as applied to soloists cannot be directly applied to choirs. A link between SPR and a perceived “good” choral tone could exist but would have to be interpreted differently than in the case of soloists. It was also found that a possible link could exist between frequency peaks in LTAS and a choir‟s intonation.

There is a need for a systematic collection of ideas concerning blend in choral sound. Many authorities discuss blend, but their concepts of the term are very divergent. These divergent concepts lead to emphasis of various factors which are important to the development or achievement of blend in choral sound. This emphasis in turn leads to various methods of achieving blend. Authorities ascribe several definitions to the term blend, as it relates to choral tone. These definitions should be studied collectively in order that a clearer concept of the term blend in choral sound may be developed. In studying blend in choral sound, several factors are generally deemed important. No study has been made which leads to a consensus concerning the relative importance of these factors. Scientific studies have been made of these factors, but the results have not been compiled and presented in one source. Authorities employ various methods in working with the factors which affect blend in choral sound. No study has been made which includes these methods. It is hoped that this study will contribute to the collecting and organizing of ideas regarding blend, including its various definitions and its important factors. It is also hoped that this study will contribute to the understanding of these factors as they relate to the achievement of blend in choral sound. It is intended that this study will present this information in such a manner as to be of assistance to the musician in the field of choral music.
