The TPerc Labs is where we develop projects to further the education of our members and/or to enhance indoor percussion.  We always welcome individual or corporate collaboration on any of these initiatives.  If interested, please contact Jim Schoenduve at Team Percussion.  (415) 968 9046

The Quantified Percussionist

  Indoor Percussion is a physically demanding activity where members wear drums weighing up to 43 lbs while performing sophisticated musical scores to precise choreographed routines.  It requires a unique combination of strength, stamina, musicality and grace.  The 'Quantified Percussionist' employs sensors to measure and signal processing to analyze various aspects of the member experience. 

A. Physiological Measurements

The 'Quantified Percussionist' project measures and analyzes physiological characteristics of team members such as EEG, heart rate, heart rate variability, respiratory rates, galvanic skin response, EOG, steps, etc. 

B. Performance Metrics

Criteria such as hand speed, force, displacement are useful metrics to measure for indoor percussion.  More significantly, precise measurement of hand, limb and foot position can be measured using the Kinect for improvement of choreographic routines for the members.

This project will help our students learn about engineering while pursuing their passion for indoor percussion. 


The Silent Metronome

   Metronomes provide the basis for time for the ensemble during rehearsal.  For indoor percussion, the metronome tone must be very loud to be heard over the sound of the drums and the tones are distorted because rehearsals are conducted inside structures such as basketball gyms.  Furthermore, the tones interfere with the audio recordings of rehearsals.  The Team Percussion 'Silent Metronome' project transmits a much more precise tone to the members of the ensemble without a loud audio tone.  The result will be 'cleaner' renditions from Team Percussion.


Audio Signal Processing

      Using digital signal processing techniques, members can better understand the physics of music through visualization and provide for more consistent and accurate tuning of instruments. Team Percussion contributes to the music analysis community through various open source projects such as Freesound, Audacity, AcousticBrainz, etc. Adobe Audition is also utilized for audio analysis.


By utilizing DSP within the Team Percussion program, students get 'real world' experience using the latest technologies.  This is particularly relevant for those students interested in the pursuit of audio engineering as a career.
