Dear 30dayssinger, 

First of all, my compliments on your many high-quality videos.

I just have one stylistic question:

In your videos you often refer to using a good warm voice and not imitating breathy vocalists. 

I would like to use my voice the way Billie eilish, Alice Kristiansen use it. (Very soft and sensitive).

Is their use of the voice wrong then, or have I misunderstood?

Thanks in advance for any help.

Greetings, Thibault

Great question! Breathy singing is fine for stylistic effect, and in moderation. It becomes problematic when a singer uses a breathy tone exclusively, or when they're physically unable to sing with stronger cord closure (when the song requires it).
