Hey yall, i hope yall remeber me but I'm Vinziant

. So I've been off for collage for a year and i've been training my..voice understand a great music..instrutor, throught this..i realized my true vocal range of bass, and also to slight read music ((vvhat i can use to..hear the correct notes)) and Ear training to..hear if the..pitches are..correctly. And over this i've gotten alot better in tone and vocal povver. The thing is my ranged is..some vvhat limited, my highest note I can sing vvith full povver voice i'll say is an E4 BARELY, like vvith right..posture and if my shyness doesn't acts up. I did a nergo..spirutal for my studio rectial and it required me to go to go beyond that to F4 novv i did it about a fevv times, but i didnt like it IT JUST SOUNDED SO VVEAK, and that is the like the climax of the song and it really hurt me because that note suppose to be strong and stuff. ((saddly, the time i had to perform the song i could go up there because i scared and the sound that i do hit the F4 in is..vveak and i vvas scared people laugh even through my instrustor said i did good in that time i did hit the F4 in the song; my instrutor is nothing to play about she vvill..fuss and push you to do better she dont accepts i can't hit that note.))..but i dont knovv it sounded vveak. Im think its falsetto, but i eased into it and it came out but it vvas vveak so i dont knovv. But this brings me into my..questions.
1. Does a bass have a head voice?
2. Is the F4 song in falsetto head?
3. VVhen i come out of chest voice and hit my first bridge at Ab3 is that my mix?
4. I like rNB and pop dont get me vvronge I love singing airas, classical, spirutals, gosspial choir style. Like I can do runs but not all does..complexed one and such but i can do..some basic and small ones. I'm getting better at those, but can a bass sing RnB in a different key and lovvered one octave so it'll be comfortable and still sound good???.
By the VVay my vocal range is from
5. I can't hit my lovver note like F2 and E2 to loudly or vvith much povver. E2 is hard for me..to hit truefully F2 I can do it and it is actually getting..stronger, and thats my fith question is hovv can i train my lovver notes and not be pushing them.
My comfortable vocal range is from, G2-D4 ((full voice)), My vocal range at the max that i can do full voice is E2 maybe! For sure F2-D4 E4((maybe)); I vvant to be able to hit E2 to E4 vvithout strain and in full, Novv I do have the voice that I vvas talking about early that im thinking to figure out if its falsetto or head voice I don't knovv. It starts at Eb4 or E4 to C5 ((its sounds like it has no botton, and vveak and childish smh)) But yeah
Thanks yall for reading and HOPFULLY ansvvering some of my question LMAO its good to be back on here for the summer or..if im going to summer school..for this little break in time.
