The Robert Tucci RT-72 tuba mouthpiece is primarily designed for F and Eb tubas. It's considered to be a larger model mouthpiece for these instruments, so it works well for players that want to balance powerful brass sections or, want to use the F or Eb tuba as the primary instrument for brass quintet. The RT-72 has also been a very successful tuba mouthpiece for intermediate tubists who need to go larger than beginner models, but not too large!
