We are a group of singers.  We call ourselves a choir.  A gospel choir. Me, my mom, my dad and a few other people.
Nice! What kind of music do you guys sing?
We sing gospel music. 
Where do you sing? 
We sing as guests at a lot of churches.  Gospel music falls under the christian music umbrella.
Oh okay. I've heard gospel music before! I think it requires a lot of singing skill. Do you know if it's popular in any countries? 
Gospel music and Gospel choirs are popular world-wide.  Gospel music goes way back to origins in the 17th century. 
Wow! What else can you tell me? that's a long time.
Gospel music has a very distinct sound.  Strong harmony and dominant vocals are very noticeable. Our choir uses this a lot.
