In this log entry, I use a virtual base guitar as an example to show how multiple keypoints in combination can be used to control a single instrument.

The movements of the RIGHT_WRIST keypoint control the trigger of a base guitar sound, while the position of the LEFT_WRIST keypoint defines which note is played. Additionally, as an extension of the way a real base guitar is played, the position of the RIGHT_WRIST keypoint allows to override the note defined by LEFT_WRIST, so that the fundamental note of the scale is easily accessible.
