Because the bass clarinet is so long, it has a wide note range. Meaning that it can play really low notes as low as a tuba can play, and really high notes as a flute can play. Thanks to the wide range the bass clarinet can play, it can play some really important parts in music. In a musical piece, there is a balance to how loud an instrument plays, and it is based on high and pitched it is. If it is high pitched, like a flute, it is the softest as higher pitches are easier to hear. If it is low pitched, like the bass clarinet, it plays the loudest as it may be harder to hear. This can be called the Triangle of Sound with the lower voices in the bottom and the higher voices are to the top. This makes the lower voices the foundation of the entire band. The lower instruments like the tuba or the trombone do not have a wide range of notes as the bass clarinet does. So they are limited to what they can play and how they can, but the bass clarinet is not. It can play the slow harmony in a dark piece, or it can play a fast upbeat melody in joyous piece. From songs about spring time to songs about death, the bass clarinet can play it all.
The bass clarinet is the most important and most beautiful instrument in a band. It is unique shape that gives its beauty and the amazing playing abilities that can do on it. With its abilities to play just about anything and its role as the foundation of the band, it has a unique position in what part it plays.
