The number of methods and étude collections existing for violoncello is huge. But what to do when no teacher is on the spot to explain why a certain passage of the concerto simply would not work out? The renowned cellist Maria Kliegel pioneers a whole new way: her experience and knowledge have been summed up to constitute the 'quintessence'. In the book, she explains in great detail technical problems, stating examples from the repertoire. On the DVD she demonstrates the correct technique, giving tips on how to master famous passages from the concert literature and on effective practising. A must for the advanced instrumentalist who looks for answers to special questions or who has always wanted to know how to overcome such technical hurdles.
