I started singing when I bought a guitar (a year ago). Since that, I noticed I can't sing properly almost all songs I play.
I've searched a bit and found out some texts about vocal range. My range now is from F2 to D4 and falsetto up to C5.
When I checked a table of common vocal range by types, it seems like I have a baritone range but without the high notes.
Recorded 3 audios to try show you what happen (all recorded during night):
Low register: Hurt - Johnny Cash
Medium to high register: Space Oddity - David Bowie (falsetto only for the highest note)
High register: All of me - John Legend (a lot of falsetto. Tried full voice in the end. Did not work)
Should I focus on my bottom range or should I try high notes? In other words, am I a untrained bass or a untrained baritone?
If I should try high, what am I doing wrong while trying sing high?
