A few months ago i was asked to perform the Cello solo of the Vivaldi Concerto in D minor (Opus 3. NO.11) on bass with orchestra because no capable cellist was available. After the performance i was asked to perform it again in October. Since its a cello solo, i am playing everything an octave higher. The hard part is not all the "runs" or how high the notes are, The hard part is making the bass sound like a cello. I understand that the bass is not a cello and therefore cannot exactly sound like one, but i still have that desire to acchieve a similar sound. Any Advice with strings setup or teqnique...
