The easiest way to identify your range is with the assistance of a tuned instrument that you can play while you sing, like a piano or keyboard. If you do not have access to the physical instrument, download a piano app, such as Virtual Piano, on your smartphone, tablet, or other device as a substitute. Using an online piano on your laptop or device will give you access to a full simulated keyboard. It will also make it much easier to figure out which notes are your highest and lowest because the app will actually indicate the correct scientific pitch notation for a key as you play it. Start by figuring out what the bottom end of your natural range is by locating the lowest note that you can sing comfortably without your voice croaking or cracking. You should also not have to “breathe” the note; that is, its tone quality should match that of the rest of your chest voice and not have a breathy or scratchy sound.  Instead of trying to pull your lowest note out of thin air, start by singing a higher note on a consistent vowel sound (like “ah” or “ee” or “oo”) and work your way down the scale into your lowest registers. If you’re a woman, start with an easy C4 (middle C on the piano), and work your way down the keys, matching each note until you hit your lowest. If you’re a man, play a C3 on the piano, and go down one key at a time from there. The goal is to find the lowest note you can still sing comfortably, so do not count notes that you cannot sustain. Once you know how far down your voice can reach comfortably, try to go a bit lower, key by key and note by note. Breathy notes that you can sustain count here, but croaky notes that you cannot hold do not. For some singers their normal and breathy lowest notes may coincide. For others, they might not. Once you have found your lowest normal-voiced note and the lowest one you can reach, write them down. Do so by identifying the piano key that corresponds to the note and then figuring out its correct scientific pitch notation. For example, if the lowest note you can hit as you descend the scale is the second-to-last E on the keyboard, then you’d write down E2.
