How to Choose the Right Clarinet Mouthpiece Reading Low C Bass Clarinet Fingering Charts 5 minutes

A Low C Bass Clarinet extends the range of a standard Low Eb Bass Clarinet down to written low C. This requires additional left pinky, right pinky and right thumb keys, changing how you approach low register fingerings and coordination.

Low Eb vs Low C Bass Clarinets: What Changes?

Because a Low C Bass Clarinet extends below the range of a standard Low Eb Bass Clarinet, it includes additional left pinky, right pinky and right thumb keys, along with alternate fingering options, for these extended low notes.

Left Pinky Keys on a Low C Bass Clarinet

The left pinky is where players first feel a difference between a Low Eb and Low C Bass Clarinet. Some Low Eb Bass Clarinets feature the Ab/G# (Eb/D#) key, but the Low D is exclusive to Low C Bass Clarinets.

Left Pinky Technique Tips

  • Use the left pinky keys to help your right pinky avoid hopping or sliding from one key to the next
  • Keep your left pinky relaxed and avoid sharp movements

When using the left pinky keys, think of them as tools to reduce unnecessary movement in the right hand. In many passages, the left pinky can take over certain notes so the right pinky does not need to hop or slide awkwardly between keys. Efficient, minimal motion will help maintain smooth transitions in the low register.

Right Pinky Keys on a Low C Bass Clarinet

Mastering the right pinky keys is essential for clean movement between Low Eb or D and other low extension notes. The added Low D key is especially helpful in many real-world musical situations.

Right Pinky Technique Tips

  • Use the right pinky keys to help your left pinky avoid hopping or sliding from one key to the next
  • Hover your right pinky close to the key surface
  • Learn all alternate versions of each low extension note

The right pinky keys serve a similar purpose to the left pinky keys: they allow you to redistribute the workload between hands so the left pinky does not need to jump between keys during fast passages. It is also important to learn all alternate fingerings for the low extension notes, as different musical contexts may call for different combinations of right and left pinky usage.

Right Thumb Keys on a Low C Bass Clarinet

If you’re new to Low C Bass Clarinets, the right thumb is the most significant distinction. On Backun Alpha Low C and Q Series Bass Clarinets, this mechanism is designed to make the lowest notes more reachable, including roller-enhanced Low Eb, C#, and C thumb keys for smoother motion and fewer thumb gymnastics with no pinching.

Why Rollers Matter

Rollers help you slide between adjacent keys, reduce friction and keep the thumb stable and efficient in faster passages.

Right Thumb Technique Tips

  • Keep your thumb anchored and avoid pulling your hand off the instrument to "hunt" for Low C or C#
  • Combine thumb drills with pinky drills, as real music frequently uses both

The right thumb controls the lowest extension notes and should remain anchored and stable. Avoid pulling your hand away from the instrument to search for the Low C or C# keys, as this can interrupt technique and stability. Instead, develop familiarity with the thumb keys so they can be reached naturally.
