What you hear in a recording cannot be reproduced in a ''real'' musical scenario like a concert for friends, family or unknowns. Remember:Nobody claps intentions... "I meant to play it like Segovia but.. damn! It did not work". This piece is magical and it needs deep understanding of each musical phrase. Leave nothing to chance. Practice time is ''the music lab'', the place where you, the wizard, mix the ingredients. Take all the time in the world and play slow enough not to allow mistakes to enter your practice. It is not mandatory to make mistakes!
