I used to play the trumpet several years ago.  I am not very good anymore.  But, my brother and I used to play classical trumpet.
Fascinating, are they brass instruments?
Yes.  In fact, since the late 15th century, the primary construction has been brass.  Do you play?
I play the harp, I don't think I have the lung power for a trumpet.
Now, the harp is a beautiful instrument; it also has such a long history.  They've been around since 3500 BCE!  I love to hear the harp.  And when the trumpet is played with it, I love the sound.  
Yes, my daughter plays the cello, we could form a small band.
There is no doubt, our group would sound heavenly.  With the beautiful harp, the lead of the trumpet, and the low pitch of the cello, we could have quite an orchestra!
I wonder who the most famous trumpet player ever is?
Pops would probably be my favorite; although I don't know if he is the most famous.  Louie Armstrong was nicknamed Pops.  
I did not even realize he played the trumpet.
