What is a key aspect of the right hand technique for playing the French horn?

A key aspect of the right hand technique for playing the French horn involves flattening the hand to support the horn's weight. This technique is essential for stability and comfort while playing. By flattening the hand and creating a more solid grip, the player can maintain better control over the instrument while also reducing fatigue during extended playing sessions. This approach allows the hand to naturally conform to the shape of the horn's bell, which helps to minimize unnecessary tension in the fingers and wrist.

In addition to weight support, properly positioning the hand can also aid in sound production and tonal control. The right hand is often placed inside the bell to help adjust the pitch and tone quality, and flattening the hand can facilitate easier manipulation of these subtle adjustments.

The other options may not adequately address the specific technique required for effective playing on the French horn, as they could lead to discomfort or ineffective sound production.
