Published in 1784 Mozart s Sonata in A major for clavier solo with the famous Rondo Alla Turca finale is one of the most popular works in the entire piano literature.Now a newly resurfaced section of the autograph has prompted Bärenreiter to issue an up-to-date Urtext edition of this celebrated piece. The editor Mario Aschauer has set new editorial standards and offers the most innovative methodological approach of our time. His scholarly-critical performance edition is the only one to remain entirely true to the sources by presenting the musical text of the autograph and the original print separately.Both forms of the sonata are historicallylegitimate; the editor has not merged the sources to produce a new text. The section on performance practice provides valuable information on Mozart s claviers as well as on the refinement of touch articulation pedalling and ornamentation.Foreword with new insights into the work s publication history (Eng/Ger)Optimum page-turns and well-presented engravingCritical Commentary (Eng)Includes valuable information on performance practice
