How should diphthongs be sung for the best effect?

Singing diphthongs effectively involves transitioning smoothly and thoughtfully between the two vowel sounds that comprise them. Holding the first vowel slightly longer allows the singer to establish the primary sound and provide a clear foundation before moving to the second vowel. This approach ensures that both elements of the diphthong are articulated correctly, contributing to a more cohesive and harmonious sound.

The technique of smoothly transitioning allows for a more natural vocal flow, making the diphthong sound fluid rather than abrupt. This results in a more pleasing auditory experience for both the singer and the listener, as it showcases the singer's vocal control and technique. By balancing the emphasis in this way, the diphthong can be heard clearly while still retaining a sense of musicality and expression.
