My singing voice, on playback, is way too low for my tastes. It sounds almost male. Is it possible to ‘fix’ something like that? Since I use a guitar to write songs, someone suggested a capo but I don’t want to be restricted by something like that. I’m a songwriter, not a singer really, but I need to be able to record and not hate the playback so much that I give up on writing.
There are definitely things you can do to access higher pitches. Much will depend on the size of your voice as well as the health of it. A good singing teacher or voice coach will be able to give you techniques and exercises to practice higher. In the meantime, humming will be helpful. You can also play around with easy little squeaky sounds. Don’t let the larynx rise up or get tense. Just play with little noises the way kids do. You can also try some sliding sounds from low to high and back to low again — like sirens in emergency vehicles. Whistle a little and think of singing in the little place where you whistle. And DO look for a teacher or coach. You are likely more a singer than you think you are. Any place to hear your songs?
