This "Concerto in F major" was amongst the first purchases that I made whilst still a young Petty Officer on H.M.S. Victorious in January 1965. I practised it many, many times and finally was able to play more-or-less fault-free albeit only when proceeding at a super slow pace. On leaving the Royal Navy in 1968 I never played it again and it was banished to my ditty box.
In 1979, on taking up the recorder again, my ditty box was emptied of recorder music which was then properly filed. At the start of my second period of intense study of recorder music in 1981, I had the good fortune to hear and tape Michala Petri on NDR (North German Radio) playing this piece. Thereafter it was a great pleasure to listen to her at the same time reading the score. Her tempo amazed me and I became fully aware that I could never play it even at a tenth of the standard of hers. The distance bewteen world-class artists and rank-amateurs is astronomic.
As can be seen from the lists below, Sammartini's Concerto in F is an obvious standard work as all the major artists (Frans Brüggen, Hans-Martin Linde, Clas Pehrsson as well as Richard Harvey) have it in their repertoire and have recorded it.
"Concerto in F" has been recorded by:
Hans-Martin Linde on "Barocke Flötenkonzerte"
