Hi Everett from what you are saying you may be a tenor but have a limited range. Your range is decided by the distance between the lowest note you can sing comfortably and the highest. Most people have between one and three octaves. Some exeptional folk can sing several octaves.

In classical music types of voice are described as follows

Soprano: C4 – C6
Mezzo-soprano: A3 – A5
Contralto: F3 – F5
Tenor: C3 – C5
Baritone: F2 – F4
Bass / Basso: E2 – E4


Most males have a tenor voice and those with lower pitched voices are bass. The important thing is to be comfortable with the key and not to try to sing outside your range as this can strain your voice and damage vocal cords. Sometimes a keychange of a semi or tone can make all the difference between handling the song comfortably and singing "sausages" (a term my pal Dave affectionately uses when a singer is unable to hit notes in a song because it is in the wrong key for the voice)
