From an aural tuning done on 2/10/2014 after a 6-10 cent pitch raise. An example of tuning based on the impact tone rather than the decaying tone. Middle strings were tuned, then a strip mute inserted, beginning from B2, then proceeding up to D5 and back down by whole steps. Then a final unison pass for that section moving by half steps. Recorded with an iPhone and Voice Memo app.
