I'm a male singer, experimenting with my voice with srutis. I noticed when I recorded myself that my voice sounds nice when I sing in 4 F, but sounds bad when I sing in 3 E, which is actually a lower sruti. How common is this, also is bad for my throat to sing high srutis despite having a tenor voice?

(I sound okay-ish in the common male srutis(csharp-d sharp), but my voice seems to sound most pleasant in F, atleast to my ears)
