The difference between range and tessitura becomes important when you choose songs, choose keys, and start singing with other people. My last blog was about range and finding your range. You can read it here.
Once you’ve found your range, the work becomes having every note in your range strong and consistent. The notes in your range should be easy to move from one to the other with even breath, support, and tone. Here’s where your tessitura comes in. The tessitura is basically the best notes in your range. Let’s say in your lower range, the last few notes aren’t very strong or the tone is not pleasing. You would not include those notes. Or in your higher range there isn’t consistently or accuracy in the highest notes. You would not include those notes. For most singers, the tessitura is in the middle, minus the highest and lowest notes. However if you are a trained singer with mastery of your voice, it is possible for your tessitura to include almost all the notes in your range.
Some things to keep in mind:
Hope this helps! Good Luck!
