The years 1927 and 1928 were important for Henriette Bosmans when she wrote two compositions that pleased her very much, a String quartet and a Concertino for piano and orchestra, still considered as one of her most successful compositions. It was performed many times by her with great success.
‘It is a technical clever work, fresh and we witnessed a great skill in the treatment of orchestral colour’, wrote Herman Rutters in his review in the daily newspaper ‘Algemeen Handelsblad’.
She was a formidable pianist and liked playing the music of Bach and Mozart, but the German romantic music had her preference. Noted was her performance of the Burlesque of Richard Strauss. More then twenty times she appeared at the Concertgebouw in Amsterdam, under well-known conductors as Willem Mengelberg, Karl Muck, Ernest Ansermet, Pierre Monteux, Eduard van Beinum and Willem van Otterloo who tragically died in a car accident on Dandenong Road near Malvern in Melbourne in the 1950’s.
Between 1919-1926 Henriette composed much for the cello, the instrument of her father, but also the instrument of her two intimate friends Frieda Belifante and Marix Loevensohn.
