1. A system for monitoring a user selected kinetic activity at user selected points on the body and generating immediate biofeedback information to the user, comprising:

  • means for emplacing transducers at the user selected points on the body,a signal processing circuit for processing of inputs from said transducers, said circuit having a signal measurement value step scale of 2 to 10 consecutive steps, preferably 3 to 5 steps, each successive step having a corresponding audio tone, each successive tone being 1/3 to 1/1 octave higher in pitch than the preceding tone,an audio tone generator circuit for generating said audio tones,means for calibrating said step scale to the range of kinetic activity value to be recognized,at least one motion sensing transducer, said motion sensing transducer having a connection to said signal processing circuit, said processing of inputs further comprising comparing the result to said step scale value during a cycle of said kinetic activity, the occurrence of a said result equaling a step value causing the generation of said corresponding audio tone,means for maintaining the highest pitch of any said audio tone occurring within said cycle of said kinetic activity for at least 0.1 seconds.
