These are sounds which are not connected to melody or text but are sounds that underline the expression or style of a singer. Many effects are produced in the vocal tract. All singers are different. Consequently, every effect must be specifically designed to each singer, taking into account their anatomy, physiology, fitness, energy level, and temperament.
Before you start working with effects it is important that you can control the three overall principles, the chosen mode, and the sound colour.
Effects might be:
- Creak and creaking
- Intentional vocal breaks
- Air added to the voice
- Ornamentation technique (rapid run of notes)
