Bartek Marusik showed 100 guitar enthusiasts in 3 days, using 20 T.Burtos, during 9 lessons what a five line staff can be used for. We give our word that the participants of this workshop tortured themselves with musical knowledge for 3 days out of their own free will. This campaign, held in order to show the usefulness of intervals, scales and harmony, was not only voluntary, but its popularity exceeded our organizational possibilities. It was held in the T.Burton – Electro-Harmonix – Garrison – Taylor tent during the 2006 Woodstock Festival as part of the Academy of Fine Arts.
