On 1 April 1777 the oboist Giuseppe Ferlendis entered the service of the Salzburg court chapel. It was for Ferlendis that Mozart wrote his only oboe concerto. At the very latest it must have been finished by 22 September 1777, the day on which Mozart set out on his great journey to Mannheim and Paris, taking the score with him. In Mannheim he met the oboist Friedrich Ramm, to whom, oddly enough, he also gave this concerto as a present: “I made him a gift of the oboe concerto, which is being copied out in a room at Cannabich’s. Ramm is beside himself with delight; I played the concerto to him on the piano at Cannabich’s” (letter of 3 December 1777 to his father). Ramm performed the Oboe Concerto several times in Mannheim, always to good effect: “Then Herr Ramm, for the fifth time, played the oboe concerto I wrote for Ferlendis, which is making a great sensation here. It is now Ramm’s cheval de bataille” (letter of 14 February 1778). Apparently the score remained among Mozart’s possessions upon his return, for years later, writing on 15 February 1783 from Munich, he asked his father to forward it to him: “Please send me at once the little book with the oboe concerto I wrote for Ramm, or rather for Ferlendis. Prince Esterházy’s oboist [Anton Mayer] wants to give me three ducats for it.” A short while later, on 12 March, he repeated his request with a note of urgency: “I entreat you most earnestly to send me the oboe concerto I gave to Ramm – as soon as you possibly can.” Finally, Mozart acknowledged receipt of the “little book” (i. e. the score) on 29 March. Since then it has vanished without a trace.
