Descripci Poulenc completed the Sonata for Clarinet and Piano in 1962, having contemplated the project for at least five years. After his sudden death, the notational ambiguities remained unresolved, and accordingly contaminated the text of the first edition which was published later that year.The revised edition of 1973 attempted to grapple with textual problems. Although they made a numberof useful suggestions, the scope of amendments did not extend to improving the notational style of the predecessor. The objective of Millan Sachania in this revised edition 2000 is to reassess Poulenc痴 intentions, and remedy errors in the previous edition. The original copy has been re-inspected and is hoped that original indications have been restored.
