Edge is a mode with the possibility of powerful volume, extending from medium loud (‘mf’ or ‘mezzo forte’) to very loud (‘ff’ or ‘fortissimo’). We divide the volumes in Edge into loud and medium. In a volume scale from 0-10, loud Edge represents volume 7-10 and medium Edge represents volume around 4/5-7. Edge is not possible below volume 4/5.
The volume can be varied more easily in the lower part of the voice than in the higher part, as you can usually sing Edge quieter in the lower part of the voice. In the beginning the higher the pitch, the louder the volume becomes for this mode. Later when you have obtained greater control over Edge, you can practise singing medium volume in Edge. In medium Edge, you will hear that the character often also becomes less Edgy/sharper.
