Chest voice

Hey!

So with my chest voice, it does not seem to go as high as other female singers... My limit is around a C4-E4 in chest voice. Whenever I go above it feels uncomfortable and I need to transition to a mix. Is this something I need to work on or is it just my own unique voice? 

I can relate! That E4-G4 range (for females) is what we can call "upper chest". There's definitely a "lift" in energy there. I do think it's important (for contemporary singing) that you work on those pitches (until they feel as strong and comfy as your speaking voice). A few tips:

The vowel really matters, so determine which vowel shape feels most comfortable.

Let the jaw drop, and don't "back off" from the volume (or you're likely to crack).

Try "speaking" or "calling" on pitch in that range. 

Try "twangy" sounds (like a country singer). 

Take it slow (get comfortable with the Eb4 for a while, then the E, and so on).

Consider singing some tenor songs that "live" in that range for a while, too: https://www.youtube.com/watch?v=OCGo4MWZH3M&t=1s

Here's a list of lower-voiced female singers to listen to as well: https://www.30daysinger.com/blog/how-to-choose-a-good-song-for-your-voice-considering-range-registration-and-style

I once had a female student whose voice consistently cracked above C4 (in chest voice), and we eventually got her singing G4s. It was slow work, but it's possible!

Thank you very much!

You're welcome! :)
