What distinguishes bow handling on cello and bass compared to violin and viola?

The distinction in bow handling between cello and bass compared to violin and viola is fundamentally tied to the structure and balance required for each instrument. On cello and bass, the pinky finger typically rests next to the middle and ring fingers on the bow. This positioning provides additional stability and control, enabling players to manage the greater weight of the bow and the larger string length effectively.

In contrast, the design of the bow grip on violin and viola allows for a slightly different finger arrangement, often promoting a more open and arched hand position. The heavier construction and size of the cello and bass necessitate this variation in finger placement to support the unique demands of these instruments.

The other choices do not accurately capture this fundamental aspect of bow handling. For instance, the notion that the pinky finger rests above the bow fails to account for the specific grip essential for larger instruments. Similarly, hand position indeed holds great relevance for cello and bass just as it does for the other string instruments, making the idea that hand position is not relevant incorrect. Lastly, while arched fingers are common in string playing, they are not strictly universal or defined for all circumstances, especially when contrasting hand positions on various instruments.
