I think that Soprano, Alto, Tenor and Bass uses the same ranges of notes but their tonal characteristics had given them distinct assignment in the musical scale. Generally, Soprano and Alto parts were given to ladies, Soprano taking the higher notes. Tenor and Bass parts were given to men, tenor taking the higher notes. Though there were overlaps in their voice ranges we could still map them like these: Soprano for the highest frequency voice spectrum, Alto taking the high-mid, Tenor taking the lower-mid and Bass for the lowest frequency voice spectrum. This is how I understand this but others may give some more light.
What amazes me is that the fundamental frequncies of all those instruments are not even reproduced by my tweeters, which only work above 2500 hz! Thank goodness for the harmonics and overtones or we'd be listening to speakers with a midrange and woofer only
