Sing songs within your range, or comfort zone. Your range is the group of notes you can hit comfortably without cracking or missing notes.A large range covers both high and low notes, like Marvin Gaye's famous 3-octave range. A small range sticks to simple, easy notes, like Joe Strummer's infamous 3-note range. Any range can work in pop music, but only if you know yours and know how to stay in it. The better your singing technique, the better your range.
