I personally think that Marcos Machado as well as being a great performer in terms of the "classical double bass" and recognized around the world, is also a valuable and careful teacher of his instrument. Already in this exceptional first volume you will discover the most innovative techniques concerning the left hand not only to the strengthening and agility, but especially regarding concepts such as Pivot, Crab Technique, Permutations and so on who are the only ones able to make you able face a new instrumental repertoire much larger and technically complex as the bass transcriptions also in the original key taken from cello concerts, addiruttura, from the violin. A new way of conceiving the left hand technique that takes cues from the great master Francois Rabbath and that, thanks to these specific pure technical exercises and well oriented to the development of a "Higher Technical and Advanced" will bring scholars to consolidate and reinforce his left hand, in addition to better design a "New technology of the Thumb Position" advanced level. This first volume I recommend him highly to bass players and teachers who already know the advanced techniques of the old mold in order to broaden their knowledge and thus have a kind of "completion" of the most modern techniques on your bass. A new technical vision that dr. Marcos Machado that will allow everyone to considerably improve their agility of his left hand, its reinforcement and many other highly innovative exercises for the Thumb Position. Highly recommended for all serious students of the double bass.
