Tuba is the largest and smallest in brass instrument. The sound is produced by vibration or buzzing from the lips in a large hollow mouthpiece. It is one of the most recent additions to the modern symphony orchestra. It is characterized by its large size and deep sound. They are used in both symphony orchestras and military bands. In the tuba lessons, through special exercises, the student strengthens his lungs, since the instrument requires force in the blast. At the same time, with the strengthening, the duration of the blast is achieved, as a result of which the student can gradually perform even more demanding pieces of music.
