I sometimes sing to a piece of classical music and sometimes it reaches high notes at the high limit of my voice.
I used to be able to sing all the way from very low in the contra to very high in the 2nd and 3rd octaves.
Now that my estrogen and progesterone is higher it is more restricted. My ability to sing high notes was lost but even more so was my ability to sing in the bass clef. Now my bass clef notes are restricted to F in the small octave at the low limit. As I got older I was able to get to higher notes.
In fact now I can sing up to like F in the 3rd octave at the very highest maybe F sharp.
The thing is that my singing from F in the 2nd octave upwards is very squeaky, almost like the flute or recorder when you first play it.
Higher female hormone should mean soprano notes are easier and thus less squeaky. However they just kept getting more squeaky as my female hormones rised which is strange. Not only that but I have been singing more often in the soprano range than I did before my drastic rise in female hormones.
Could my vocal cords be getting more and more stressed out and thus predisposing me to laryngitis and causing my squeaky soprano notes?
