Backun's Q Series is a professional clarinet line developed to bring many of the maker's higher-level acoustical and mechanical concepts to advanced and professional players. In A, the model is well suited to orchestral, chamber, and recital work where a player wants a refined, centered response and a serious counterpart to a Bb clarinet.

The Q Series A clarinet is intended for advanced and professional clarinetists, particularly orchestral players building or refining a matched working pair.

Common Questions About the Backun Q Series
Where does the Q Series fit within Backun's clarinet lineup?
The Q Series is positioned as a professional instrument that incorporates higher-level Backun design features while remaining below the maker's custom-level models.
What does the left-hand Eb key add?
The left-hand Eb key provides an alternate left-pinky option for the Eb and Ab key function. It can simplify passages in which the right-hand pinky is already committed to another key.
Why are two barrels useful with an A clarinet?
Two barrels give the player additional options for managing pitch, response, and resistance as performance conditions and ensemble requirements change.
