Double bassists either stand or sit to playing the instrument. When standing, the double bass‘ height is set (by adjusting the endpin) so that the player may easily place the right hand close to the bridge, either with the bow (arco) or plucking (pizzicato). While personal opinions vary, often the endpin is set by aligning the first finger in either first or half position with the player’s eye level. While sitting, a stool (measured by the player’s pants inseam length) is used. Traditionally, standing has been preferred by soloists although many now choose to play sitting down. Proponents of playing while sitting on a stool argue that it is easier to perform high-register passages, because they can steady the instrument between the knees.
