An audio feedback signal for a subject engaged in an exercise includes a reference note (of a musical scale) that provides a marker of the goal or target position of the exercise for the subject, and a sequence of real-time feedback notes that define progress towards the goal while the exercise is underway. By providing the reference note with the feedback note, the listener can instantly understand whether they have presently reached the goal. The progress is defined by having at least 3 distinct feedback notes mapped to respective sensed ranges of positions within the exercise, and this provides multiple opportunities for the exerciser to compare the feedback and reference notes, and provides cognitive feedback to the exerciser.
