如何擴闊音域?

singing scales is the most basic and effective way to widen your singing range. i used to sing only soprano, but after practicing singing scales for a good while, and a lot of singing in and outside choir, my range was widen to from high soprano to alto. singing scales could be really boring i know, so if you don't want to sing scales, i think you can choose to singing songs that are in your range, but in a higher key. or you can try singing songs of different ranges and practice with singing them. it is a much more interesting way to widen your range.
just one reminder, don't force to sing too much outside your range. if you force singing outside your range, it will hurt your vocal cord a lot. and as you should know as a singer, hurting your vocal chord does no good for singing at all.

唱多些SCALES會有少少幫助
