Before you identify your own vocal type, it’s best if you understand what the options are. In the simplest terms, there are three types for female vocalists—Soprano, Mezzo-soprano, and Contralto (or Alto)—and four for males—Countertenor, Tenor, Baritone, and Bass.
The best way to discover what your voice type is might require you to either play an instrument yourself or to work with a musician. First, you have to find your lowest note by having someone play a singular note on a piano while you match it with your voice. Then, do the same thing, only on the higher end.
Once you jot down the highest and lowest notes you can reach with your voice (which also requires you or your partner to understand these notes and how to write them out), you’ll have a range. That range should put you clearly into one of the aforementioned groups. For a list of note ranges, check out City Academy, which goes into further detail for those who have a slightly deeper understanding of the scales of music.
