REASONS TO PURPOSEFULLY CHANGE OUR NATURAL VOCAL TONE?

There are reasons to purposefully change our natural, habitual vocal tone. Here are a few:

The tone we use strains or fatigues our overused speaking or singing voices.

We want a tone of voice that commands more authentic attention to the message, and gets a stronger emotional response.

We don't like the tone we hear in our recorded voice. 

We need to blend with others in a group.

We need to match a particular lead voice to which we are singing background or harmony vocals.

We want to transform our singing and/or speaking voice into a particular character for acting in plays, musicals or TV/movie scenes, for voice-over roles, for reading book passages out loud, for speaking to specific kinds of groups.

We want to sing a cover song and sound just like the original, such as Karaoke singing or simply experimenting with different vocal styles.
