Dear Sirs,

                                               re: Martinu “Sinfonia concertante”

                I am very glad you let me have the orchestra material; thank you so much for it. Enclosed you find the completed and signed Agreement. The Basler Kammerorchester will transfer the 35 Guineas to you by clearing.

                I should be grateful if you sent me a copy of the finally printed score, as soon as it is ready. My own has got all the mistakes that are still to be corrected before the final printing. Furthermore I should be obliged to you for a new set of the solo parts as well. In my set there is that bad mistake I poi nted out to you and which was to be corrected before printing.

                With best wishes for a happy New Year I remain

                yours very truly
