This may seem like something frivolous and esoteric, but it really does make a difference to the quality of sound, and to the synchronization at the end of a phrase.
I find that it’s not enough to ask your group to sing through the singable consonants at the end of a word – for example, the ‘ng’ at the end of the word ‘song’. In order for the richness of the sound to continue, the singable consonants must be preceded by a rethinking, and an intensification of the target vowel.
So the word ‘song’ would actually look something like this……
Not that there would be an accent on the target vowel intensification – just a mental recreation of the vowel as it attaches to the singable consonant or consonants.
Last night my chorus seemed to find it helpful to imagine a vowel-filled bulb attached to the final singable consonant.
Regardless of what imagery is used, the actual rethinking of the vowel before the final singable consonant is what is important.
